Home Alone is a 1990 American comedy blockbuster film written and produced by John Hughes and distributed by 20th Century Fox. It was followed by two theatrical sequels and two made-for-television films.
The film follows Kevin McCallister (Macaulay Culkin), an eight-year-old boy whose wish of his family to disappear comes true when they accidentally leave him at home when they go on a vacation to Paris for Christmas.
While initially relishing time by himself, he is later greeted by two burglars, Harry and Marv, who are played by Joe Pesci and Daniel Stern, respectively. Kevin eventually manages to outwit them with a series of booby traps.
The McCallister family prepares to spend Christmas with Peter and Frank's brother, Rob, in Paris, France. They gather at Peter and his wife Kate's home in Chicago the night before their flight. 8-year-old Kevin, Peter and Kate's youngest son, finds himself the subject of ridicule by his cousins and siblings.
As the family rushes around the McCallister home, packing their things, a questionable police officer stands in the foyer, attempting to find an adult to speak with Kevin complains to his parents about his uncle Frank and he is instructed to pack his suitcase. However, his siblings refuse to help him.
Kevin goes to his older brother, Buzz, to ask him if he can sleep in his room for the night because he knows his little cousin Fuller will wet the bed they will be sharing. Disappointed for even asking, Buzz replied “I wouldn't let you sleep in my room, if you were growing on my ass!” Later Buzz tells him and their cousin Rod McCallister that their next-door neighbor, Old Man Marley is the "South Bend Shovel Slayer," who is rumored to have murdered his family and half of the people on the block in 1958. Buzz tells them that he salts the neighborhood sidewalks with the remains of his victims, which then turn to bodies, then mummies. This frightens Kevin.
A Little Nero's Pizza man arrives at the home and waits alongside the questionable police officer. Frank comes and takes the pizza, but leaves the responsibility of paying for it to his brother and does not stay around to speak with the questionable officer. Peter briefly speaks with the officer, who inquires about the security of their home and he is taken by Buzz to go eat pizza and Kevin rushes to the kitchen to get his favorite pizza.
During dinner, Buzz is seen shoving an entire plain cheese pizza (Kevin's favorite) in his mouth. Kevin looks for his favorite pizza and when he does not see any, he asks if anyone ordered some. Buzz responds that they did but somebody has to barf it all up because it was all eaten. This annoys Kevin and he sees Fuller smirking at him when he drinks a can of Pepsi. Knowing Fuller was deliberately doing this to urinate on him while sleeping, Kevin is angered further. Buzz then begins to feign throwing up and Kevin runs over and tackles him, pushing Buzz back, accidentally spilling milk on the airline tickets and passports. This results in a huge scene in the kitchen which causes wet plane tickets/passports, all the pizza to be ruined, Uncle Frank to spill Pepsi on his pants, and Fuller pinned between a chair and the wall. An infuriated Kate breaks up the fight between Buzz and Kevin and firmly asks Kevin what his problem is. He replies that it is Buzz's fault because he ate the whole plain cheese pizza on purpose, then begins ranting on how he hates toppings. Kevin is interrupted by Uncle Frank who shouts, "Look what you did, you little jerk!". This silences the entire family, angrily staring at Kevin. Kate orders him upstairs with one of Kevin's siblings insulting Kevin, pays the pizza boy, and briefly speaks with the questionable officer of their vacation. While she resumes to take Kevin upstairs, he tells her the home "is in good hands" and leaves. Kate leads Kevin to the third-floor bedroom of the house as a punishment, where Kevin wishes his family would disappear after Kevin angrily tells Kate that everybody in this family hates him and wishes that he would never sees his family again and Kate firmly tells Kevin to say it again as it would might happen.
During the night, high winds pick up, causing a tree branch to fall over and land on an electrical wire, resulting in a power outage. The family sleeps in and desperately rushes to pack their stuff to catch the vans that will take them to the airport. Mitch Murphy, a neighbor, is mistaken for Kevin in a head count, and the family hastily depart to the airport.
Kevin wakes up to find the house empty as the family's flight takes off. Upon realizing he is home alone, he is overjoyed to find that his wish came true and begins doing whatever he wants, such as jumping on his parents' bed and getting into Buzz's belongings, including his BB gun. He then eats junk food as he watches Angels with Filthy Souls, a film that he was prohibited from watching the night before by Uncle Frank; however, the film's shooting scene ultimately startles him, and he calls for his mother.
During the flight, Kate finally realizes that they have left Kevin behind. Meanwhile, Kevin sleds down the stairs in his home and out the front door. After her realization, Kate is comforted by the family, who offer nothing that soothes her guilty conscience. Kate realizes what kind of terrible mother is she.
The "Wet Bandits" Marv and Harry — the latter happening to be the supposed police officer — observe the neighborhood, planning robberies around the security information Harry has gathered about each home.
Kevin sleeps whilst How the Grinch Stole Christmas plays on the television. Harry and Marv attempt to break in, but Kevin hears them and turns on a light, causing them to flee as he hides under his parents bed.
Once the family is in Paris, Kate calls the police in Chicago, has Peter book a return flight, and has Frank's wife and her sister-in-law, Leslie call everyone in Kate's address book.
Deciding he is no longer afraid, Kevin comes out of hiding and goes outside, declaring that he is not afraid anymore. However, he encounters Old Man Marley and screams in fear before running back inside.
Kate reaches the Village Police Department on the phone and requests them to send someone to check on Kevin and tell him that the family will be returning home. However, the department misunderstands her inquiry at first and finally sends an officer, who knocks on the door, but Kevin is too afraid to answer the door. The officer judges that there is nobody home and the house is secure.
Kate and Peter attempt to book a return flight back to Chicago, but find that everything is booked. She decides to stay at the airport to be on standby in case a seat opens up as the rest of the family goes to Rob's.
After showering, Kevin uses his father's grooming products, including his aftershave, causing Kevin to scream from the burning sensation. He then goes to Buzz's room and attempts to climb the shelf to reach his "life savings," but causes all of the shelving to fall.
Kevin notices the Wet Bandits' van in the Murphy driveway and notes that he thought the Murphy family had gone to Florida. As the burglars raid the Murphy home, they hear a message on their phone from Peter indicating that the McCallisters are not home.
Kevin goes to a drugstore to buy a toothbrush and asks if it is approved by the American Dental Association. As the store's staff attempts to confirm, Old Man Marley enters, causing Kevin to flee the store, unintentionally shoplifting the toothbrush. A police officer chases Kevin, but loses sight of him at an ice-skating rink. Kevin walks home, dismayed that he has become a criminal.
After Marv leaves the water running in the Murphy home – much to Harry's disapproval – they argue and almost run over Kevin in their van. Kevin finally recognizes Harry and starts to run as the suspicious burglars follow him. He reaches a church and loses the bandits by posing as part of the church's Nativity scene display. He then runs home, declaring he will be ready when the burglars return.
Later that night, the burglars arrive outside the McCallister home, but Kevin has constructed an elaborate silhouette display, making Marv and Harry think there are people there.
In Paris, the McCallister family watches It's a Wonderful Life as Frank brings out shrimp, ignoring his sister-in-law and Rob's wife Georgette, who says the shrimp was going to be eaten later. Peter tries calling someone on the phone to assist in reaching Kevin. Kevin's sister, Megan, expresses her worry about Kevin to Buzz, but he insists that their brother will be completely fine.
Kevin orders a cheese pizza for himself and directs the pizza boy to the back door as he plays and pauses Angels with Filthy Souls, convincing that the character in the film is speaking with him and, eventually, shooting at him, making the pizza boy flee the property.
In the morning, as Kevin readies himself for the day, he lipsynchs to the Drifters' version of "White Christmas" and once again screams from his father's aftershave as Buzz's tarantula roams free after escaping as a result of Kevin accidentally breaking the shelving.
Kevin goes to the grocery store, where he encounters an inquisitive cashier. As he walks home, the grocery bags break. He then returns home and does laundry.
Harry sends Marv to check the house. Kevin, noticing Marv's presence, turns on Angels with Filthy Souls and enhances the film's sound of gunfire with firecrackers in a pot. This scares Marv away from the home; Marv then reports the events of Angels with Filthy Souls to Harry, thinking they actually happened inside the home.
Kate eventually reaches Scranton, but there is no flight to Chicago available. Desperate to return home, she is overheard by Gus Polinski, the "Polka King of the Midwest" and his band, the Kenosha Kickers, who are driving to Milwaukee after their flight was canceled. He offers to allow her to ride with them in a van, dropping her off in Chicago along the way. Kate accepts the offer and rides with the polka band.
On Christmas Eve, the burglars sleep in their van outside the home until they observe Kevin cutting down a tree and realize that he has been deceiving them. As Kevin decorates the tree, he sees Harry's reflection in an ornament and feigns calling for his father. He opens a window and overhears Marv and Harry planning their break-in to the McCallister home at 9:00.
Kate rides with the band as they play "Deck the Halls" in the van, Gus offering to let her play his clarinet.
After going to a fake Santa Claus and requesting he ask the real Santa to bring his family back instead of presents, Kevin goes to the church, where he sees a local choir perform and encounters Old Man Marley, coming to discover that he is actually a very friendly and kind man and that none of the rumors about him are true. Kevin learns that Marley has been estranged from his son for quite some time, thus separating him from his granddaughter, who is singing with the choir. Kevin urges Marley to make amends with his son for Christmas and Marley agrees.
His own spirits lifted by encouraging Marley, Kevin returns home to prepare a series of booby traps about the house before 9:00 pm. Harry and Marv torment Kevin at the back door and he shoots Harry in the crotch with Buzz's BB gun through the dog door. Marv sticks his head through the dog door and is shot in the forehead.
Harry goes around to the front door, but slips on the icy stairs. Marv does the same at the basement steps, sliding down on them to the door and struggles to stand up in the frozen ground. Harry again attempts going up the front steps, but falls again. Marv finally manages to stand and enters the basement. When he attempts to turn on a light bulb, he instead pulls an iron down the laundry chute and is hit in the head.
Harry once again attempts to climb up the stairs and is successful this time. He grabs the doorknob, which burns his hand, which he cools in a pile of snow. Marv struggles up the tar-covered basement steps — losing his shoes in the process — and falls down them after stepping on a nail.
Harry then attempts entering through the back door, but his head is burned by a blowtorch as he enters. He then cools his head in the snow. Meanwhile, Marv leaves the basement and slips again. Harry rushes through the kitchen door, knocking down the blowtorch, and angrily asks Kevin where he is. Marv rushes to a window.
Kevin torments Harry, who then walks into the glue-covered plastic wrap and has feathers blown onto him. The barefooted Marv enters through the window, stepping on glass ornaments. The burglars join back up again and slip on Micro Machines. They then try chasing Kevin up the stairs, but are hit by paint cans, which knock out Harry's gold tooth. Kevin calls the police, reporting a burglary in the Murphy home. The burglars chase him, while Harry trips over a wire, knocking him unconscious, and Marv manages to grab his leg on the attic steps. Kevin grabs Buzz's tarantula and put it on Marv's face, allowing him to escape. Marv screams and throws the tarantula on Harry as Kevin ziplines to a nearby treehouse. Marv, trying to hit the tarantula, then hits Harry with his crow bar.
After an angry outburst from Harry, the bandits pursue Kevin again as he reaches the treehouse. They try climbing over to the treehouse, but this is foiled by Kevin cutting the rope with a pair of hedge clippers, causing them to be swung into the side of the house.
Kevin then flees to the neighboring Murphy home's basement. However, the Wet Bandits ambush Kevin at the top of the basement steps. They discuss doing the same things to Kevin that did to them, Harry threatening to first bite Kevin's fingers off, but Marley intervenes and hits them with his snow shovel, thus saving Kevin, and returns Kevin home. Shortly after Kevin is returned home safely, Harry and Marv are arrested. Additionally, the police have now become aware of every house the Wet Bandits have targeted due to Marv's habit of leaving the household's water running as a "calling card." Kevin then places some cookies and milk on a table, having set up Christmas all by himself.
Kate speaks with Gus, guilty of leaving Kevin behind and thinking that she is a bad parent. Gus insists that she is not a bad parent compared to any of those in his band and he recounts a story of leaving one of his own children at a funeral parlor.
Kevin wakes up the next morning and calls for his mother, but is disappointed to find that he is still alone. Kate then arrives and the two reconcile before Peter and Kevin's siblings arrive, having caught the flight Kate did not want to wait for. Buzz becomes glad that Kevin didn't burn the house down. Kevin reveals to them that he had gotten groceries for Christmas, but more or less "just hung around" while his family was away.
Kevin does not disclose his encounter with Harry and Marv, though Peter finds Harry's gold tooth and wonders what it is.
Kevin goes over to the window and smiles upon discovering that Marley took his advice, and watches as he and his son reunite and reconcile. While hugging his granddaughter, Marley looks up, sees Kevin and, smiling, waves to him as a sign of thanking him, and Kevin waves back. Buzz interrupts Kevin's musings by calling out, "Kevin, what did you do to my room?!" causing Kevin to run off to another room.

Edited for Television Edit
Whenever it has aired on Disney Channel, Cartoon Network, NBC, AMC, FOX, ABC Family Airings, or Freeform, some scenes were edited like:
- When Kevin asks Buzz if he could sleep in his room to avoid sleeping with Fuller (who wets the bed when given a lot to drink), Buzz usually says "I wouldn't let you sleep in my room...if you were growing on my ass!", but in some instances, he will say "I wouldn't let you sleep in my room...if you were growing on my butt!".
- Kevin would then say, "Down here, you morons!" and "Down here, you idiots!" instead of "Down here, you big horse's ass!"
- In the scene where Kevin watches Angels With Filthy Souls, it would delete "filthy animal". He would then say, "Keep the change". It would then cut to Kevin who was yelling "Mom!"
- At the end, Buzz said, "Kevin, what in the world did you do to my room?!" instead of "Kevin, what did you do to my room?!"
- When Kevin tackled Buzz on spilled milk, Peter threw away Kevin's plane ticket.
- Even though Frank is acting like a jerk when he tells Peter, "you be positive, I'll be realistic", since their plane leaves in 45 minutes, he is actually right; it takes at least 30 minutes to get from Winnetka to O'Hare and they had fifteen people trying to make an international flight.
- Harry and Marv's van is a Grayish bluish van made by Dodge.
- When Kevin zip lined across his yard, it was clearly a stunt double.
- When Marv was walking through the snow, Daniel Stern was wearing rubber feet.
- Also, when Marv stepped on the ornaments, the ornaments were made out of glass candy.
- There is a cut scene were Rob and Georgette are welcoming the family with a poster, only for the clan to rush through the sign, ripping it.
- When it shows Kevin on a sleigh about to ride out the front door, it is obvious that the angle Kevin is at should make him crash into the wall.
- When Kevin speeds out the front door on the sleigh, there is no way he can get a lot of elevation since the stairs leading up to the front door are very small.
- Catherine O'Hara revealed in 2014 that Macaulay Culkin still calls her "Mom."
- The picture Kevin finds of Buzz's girlfriend was a picture of a boy made up to look like a girl because director Chris Columbus thought it would be too cruel to tease a girl in that manner. The boy that was used in the photo was the art director's son.
- The movie that Kevin watches on video tape is not a real film, but footage specially created. It was called Angels with Filthy Souls Along with other similar era references in the movie, this is a play upon the movie Angels with Dirty Faces (1938) starring James Cagney. Kevin uses it on the pizza boy and later Marv. Both times, Kevin was successful in scaring them away.
- John Candy improvised all of his lines.
- Marv's lines, "Why the hell are you dressed like a chicken," and, "Maybe he committed suicide," were improvised by Daniel Stern.
- During rehearsal for the scene where Harry attempts to bite off Kevin's finger, Joe Pesci actually bit Macaulay Culkin, leaving a small scar.
- Joe Pesci kept forgetting that he was filming a family movie during his character's on-screen outbursts, so director Chris Columbus advised him to say "fridge" instead.
- When Marv drops his shoe through the back door of Kevin's house while Kevin's washing dishes, he says a swear word "shit".
- When Aunt Leslie says "Fuller! Go easy on the Pepsi", it is quite clearly a close-mic voiceover recorded off set (most likely in post-production), as the rest of the dialogue has a completely different natural reverb to this line.
- When Kevin arrives home after speaking to Old Man Marley at the church, he runs right in the house without unlocking the front door - he left his house unlocked even though he knew that there were burglars in the area.
- Buzz tells Megan they live in the most boring neighborhood in America where nothing dangerous will ever happen. However earlier in the movie he seemed to really think old man Marley was a real serial killer living there.
- When Kevin is shooting at the toys that fall down the laundry chute, he is closing the wrong eye for aiming a rifle.
- When Kevin crosses himself before his macaroni and cheese dinner, he goes from right shoulder to left shoulder. Catholics go from left to right. Byzantine Catholics (and Orthodox) do go right to left but they do not use the open palms/four fingers.
- In the church, Old Man Marley's granddaughter is seen with red straight hair however, when Kevin looks out his window on Christmas day he sees Old Man Marley hugging his granddaughter, but now she has brown curly hair instead of the appearance in the church.
- The night Harry and Marv break in to the house Kevin sits down and blesses his macaroni and cheese dinner just before the stroke of nine. This draws obvious attention to his plate. Later just before Harry is covered with feathers you can see a completely different plate with three sections of food on it.
- Kevin has a pizza delivered to the house even though the phones are supposed to down. There is never any indication of if or when the phones were restored, but in the preceding scene, Kevin's father was trying to reach Kevin.
- When Harry grabs the heated doorknob with the "M" engraved on it, he grabs it with his knuckles at 9:00, facing left. After he puts his hand in the snow to cool it, he looks at it and sees the "M" upright on his hand.
- When Kevin goes across the street to his neighbors house entering through the flooded basement his clothes are soaked as he rushes up the stairs. In the next scene where he goes through the door to run into Harry and Marv his clothes are dry.
- Just before Marv and Harry step into the small pile of toy cars and slip up at the bottom of the stairs, Harry had been covered in feathers. In the next shot, there are no feathers on him at all, which mysteriously disappear.
- Towards the end of the movie, Kevin calls the police from his parents' bedroom. This should be impossible. The phones are out, which is why his parents could not reach him.
- Harry is seen wearing a wedding ring in the shot where Marv tries to kill the spider that is on Harry's chest. Later in the movie Harry is no longer wearing the wedding ring.
- The stained glass window in the church is different in the interior and exterior shots. Seen from outside, it has four panels, while inside it has seven.
- When the characters are in the upstairs hallway, the walls change back and forth from being covered with a hunt club green wallpaper to being painted in a shade of green slightly different from the wallpaper. This is because some of the scenes were recreated on a sound stage at New Trier High School and they had to try and match the colors as best they could.
- Immediately after landing in Paris, Peter McCallister leaves a message on the Murphys' answering machine while Marv and Harry are burglarizing it. The phones are still supposed to be down, and since the Murphys live across the street from the McCallisters, their phone service should be down as well.
- Kevin purchases a large bottle of laundry detergent at the grocery store. While walking home, the two plastic grocery bags he is carrying burst spilling their contents. The bottle of detergent is not among the contents that spill.
- While setting traps in preparation for the burglars, Kevin douses all the stairs outside his house with water. They freeze in a short time, indicating it to be quite cold. However, later when we see Kevin running across the Murphy's driveway, not only are there visible liquid puddles, but he runs at a full sprint without so much as a slip.
- When Kevin is at the top of the stairs getting his sled ready one shot shows him throw his scarf over his right shoulder and it slips down his arm. In the next shot, from behind, the scarf is clearly thrown behind his shoulder.
- When Kevin and Buzz are first seen fighting over the pizza Kate rushes over to break it up, in the next shot when Peter is throwing away the napkins Buzz is seen running his hands through his hair and Kate is calmly speaking with Kevin, and in the next shot after Aunt Leslie asks Fuller if he's okay Kate is seen attempting to break up the fight again and yells at Kevin.
- When Peter calls the Murphy home while Harry and Marv are robbing it, Marv picks the entire phone off the table. At this point a receiver is visible on the phone. In the next shot of Marv, it is gone. If it was in fact supposed to fall off, the answering machine would have been cut off anyway.
- The Christmas ornaments Kevin places by the tree under the window change positions repeatedly.
- After the McCallisters realize they've overslept and are frantically running around the house, Heather goes up the same set of stairs twice.
- When the McCallisters take off for Paris Orly from Chicago O'Hare, they are on board a McDonnell-Douglas DC-10, a tri-jet. When they land in Paris, they are on board a Boeing 757, a twin jet. Given that flight appears to be non-stop, the fact that they took off in a plane with three engines and landed in a plane with two engines is an error.
- The blind spot mirrors on the burglars' van change positions and sometimes disappear between shots.
- When Kevin walks up to the church at night, there is a door clearly in the very center of the building. When Kevin is shown inside the church, there is a baptistery in the center where the door was on the outside.
- When Marv goes to look and see if anyone is home, Kevin is washing up and has his sleeves rolled up. He plays "Angels with Filthy Souls" and gets fire crackers out. He reaches into a drawer to get a lighter and we only see his arms where his sleeves are down. When you see a full view of him, his sleeves are rolled up again.
- Kate tells the pizza boy that her brother-in-law drove in from Ohio earlier that day with his family, yet later in the film only Kate and Peter's cars are seen in the garage. There is no other vehicle parked anywhere near the house.
- While Kevin is in the kitchen with the whole family. Buzz is clearly stuffing the last piece of Kevin's pizza in his mouth. In the next shot he is shown with half a piece of pizza in his hand and his mouth is not stuffed.
- After Harry touches the heated doorknob and Kevin flees from the door at 80:48-80:51 on the DVD, the charcoal lighter cord runs out of the foyer into the next room from which the camera is shooting. Later, when Harry and Marv are hit with paint cans at 84:18, the door and the red-hot charcoal lighter can be seen in the background, but its cord does not leave the foyer.
- When Kate is losing her temper with the desk agent in Scranton, her coat changes in how open or closed it is between shots.
- When Marv is trying to enter the basement, there's snow on each side of the entryway. When the camera angle changes to show him from inside the basement, the snow is gone.
- When Harry and Marv are in the van and Harry is listing the automatic light cues, when Harry lists #671, the McAllisters' house, we can see the lights turn on in their reflection on the van's windshield. However in the next shot, which is of the house, we can see the lights turn on again.
- When the cop starts to chase Kevin for stealing the toothbrush, they run past a woman in a red coat with a skate on her shoulder twice.
- When Harry and Marv follow Kevin in their van, they initially stop when they are slanted on the road. After the stop for when Kevin turns around to look at them, they are fixed perfectly against the curb.
- When Kevin first uses the BB gun to shoot the figurines down the laundry chute, he pumps the rifle forward and then back at 23:21 on the DVD. Later in the film when he prepares to shoot Harry and Marv through the dog door, he pumps the rifle back and then forward at 76:12.
- During most of the film, the pictures hung on the wall going up the main staircase are consistently fifteen in number, with Peter and Kate being the lower-most bottom-row photos, and Kevin being the one at the very top end, by itself. However, in a couple of scenes there are only 14 pictures - no Kevin up top; completely different (non-closeup) photos where Pete and Kate should be; and several other pictures are different too. (The scenes are: When Kevin is crazily running around celebrating his newfound freedom (22:23), and later when he is running upstairs screaming after seeing Old Man Marley in front of the house (32:07).)
- When the shopping bag bursts while Kevin is walking home from the store, the milk carton rolls a couple of times on the sidewalk. Realistically, a full carton of milk would just fall flat and not roll, due to the weight, making it appear that the carton was empty and not heavy, thus was able to roll a bit upon hitting the sidewalk.
- When Harry slips down the stairs while trying to go in through the front door, he drops his crowbar and doesn't pick it up, but in the next long shot the crowbar is no longer on the ground right next to the steps.
- When Kevin is watching TV in the kitchen, there is a gingerbread house next to the TV in shots directly facing the TV. But when the shots are from the side (on Kevin watching TV), the gingerbread house is not there.
- When Kevin accidentally steals a toothbrush from a drug store, the cop who chases him falls on the ice after getting hit by a hockey player. He lands on his back and his hat starts to fall off his head and his arms are pushing the hat back on his head, but when the cop looks up and sees that Kevin got away, he is lying on his stomach and his hat is off his head.
- When Kevin is rifling through Buzz's trunk, a box of Junior Mints moves around between shots.
- We see Kevin purchase and use a big bottle of laundry detergent. Yet at the end of the film, he tells his family that he bought "fabric softener".
- When the crime-boss in the "Angels with Filthy Souls" movie shoots Snakes with the sub-machine gun, it makes just a few brief thin-sounding bursts of rapid-fire. Yet when Kevin is playing back his "clipped/rearranged" version of the movie to scare away the pizza-delivery guy, the gunfire is much deeper-toned and lasts a lot longer, and the individual ammo-round-discharge sounds are slower and more spaced out.
- Right after Marv hits Harry with the crowbar, due to the tarantula being on his chest, the Michael Jordan poster can be seen in Buzz's room on the door all intact. However, Kevin had previously cut the poster out to make him look like a person at the party the previous night and had him going around on a train.
- Harry protects his burnt hand with a handkerchief when he climbs along the rope towards the tree house, but alternating shots show the tail of the handkerchief either sticking out or not.
- After Kevin steals the toothbrush, he slides between a hockey player's legs. The hockey stick was between the player's leg in the first shot, the next shot when Kevin slides through the player's legs the stick is off to the player's side.
- When Marv grabs Kevin by the leg as Kevin attempts to run up the stairs and into the attic. Kevin puts Buzz's tarantula on Marv's face in order to force Marv to let go of his leg. Kevin was carrying Buzz's rifle on his back and it hadn't occurred to him to whack Marv with it which could had knocked out Marv or hit him in the arm, which the pain would had forced Marv to let go.
- While Kevin is holding shears to cut the rope in the tree house, a few inches ahead of where he is to cut you can see something that looks like fishing line that is holding up the rope. This line is visible twice, as he appears with the cutters and again just as he is cutting the rope.
- When Kevin walks into Buzz's room looking for his family after being left alone, on the bottom right of the frame, you can see a crew member's leg.
- When the female police officer transfers Mrs. McCallister to Sgt. Balzak in the Crisis Center, a crew member's reflection is seen in the glass just above the stenciled word "center."
- When the police officer is chasing Kevin, the shadow of the camera is briefly visible on Kevin's back.
- When Kate phones the Chicago Police from France, she calls them on a payphone that is a BT model that would not be seen in France.
- When the whole family arrives in Paris (which is really the underground walkway under the O'Hare Airport Hilton, that connects the terminals at O'Hare, and looks like it may include parts of the old Terminal 4), Kate uses a public phone to call home. But this device could not be French, because all phones available in France in the 90s required telephone cards and we clearly hear an operator instructing Kate to insert coins.
- When the plane takes off from Chicago, it is morning. It takes about seven or eight hours to fly from Chicago to Paris, and Paris time is seven hours ahead of Chicago time. That would put them in Paris around one or two in the morning. Yet when the plane arrives in Paris, it is already broad daylight.
- As the family bids farewell to Mom at the Paris airport, tail colors of an Eastern Airlines jet are visible outside the gate window. Eastern was a domestic U.S. airline and would not have serviced Paris.
- When Kate calls the police from France, the woman answers the phone "Village police," but when the officer goes to the McCallister home, he clearly has a City of Chicago flag on the right shoulder of his jacket.
- American Airlines has never flown a morning flight between Chicago and Paris.
- The plane shown landing at the Scranton Airport is a McDonnell Douglas DC-10. The Scranton/Wilkes-Barre Airport has never had regular service from a DC-10 by any airline. The largest planes to land at Scranton are Boeing 737s and Airbus A320s. DC-10s are far too large to be accommodated by the airport for non-emergency situations.
- The plane in the movie is a McDonnell-Douglas DC-10-10, which was flown by American Airlines, however it was only used for domestic flights due to its limited range of 3500 miles. There was a long range version used for intercontinental flights, the DC-10-30, but that one had three sets of rear landing gear. It is clearly visible during the takeoff scene that this one only has two sets of rear landing gear, so it is definitely a DC-10-10 which could have never made the trip from Chicago to Paris.
- When Marv picks up the answering machine while Peter is leaving a message the phone comes off the hook which would have affected the answering machine message being recorded.
- The Daisy BB gun shown on Buzz's wall is used as a pump-action; however, the real model is lever-action.
- Kevin manages to set up all of his traps in less than an hour. Several of those traps would take at least an hour to do by themselves. For example, the water on the porch and basement steps would not freeze into a thick layer of ice within an hour.
- Kevin's Daisy Red Ryder air rifle (notable by the distinctive shape of its trigger-guard and lever), has an additional pump-action mechanism which The Daisy Red Ryder has never had, and which would be unnecessary besides, due to the lever.
- When Kevin finally gets caught by the burglars at the neighbor's house, they pick him up and hang him from a door hook in the kitchen by his sweater. If this was a regular knitsweater, Kevin's body weight would cause the sweater to constrict into his neck and in effect strangle him. But it does not, revealing it to be that a brace is present or that it is a specially rigged sweater.
- Aside from Megan (Kevin's elder sister) and to a lesser extent Kate, the rest of the family does not seem to be concerned about Kevin's welfare while abroad.
- As Harry is driving down the driveway after a burglary he is wearing his black knit cap. Just after he hits the brakes to avoid hitting Kevin he pokes his head out to tell Kevin to be more careful and his cap is missing. However, he can clearly be seen removing his hat as he is winding the window down to speak with Kevin, which is why he is not wearing it in subsequent shots.
- On the phone with the French operator, Peter yells "I am looking for my son! Do you know where he is?" This seems a silly question since Peter should already know that Kevin is at the house, but in an earlier scene a police officer goes to the McAllister house and does not receive a response to repeated knocks and bell-ringings. It is likely that the police would have relayed this information back to the McAllisters and that this would explain Peter's frantic mood.
- When Kevin is having a flashback of his family tormenting him, we see Linnie turn around and go down the stairs. When this actually happens, we don't see her turn around at all. However, the other flashback visions were also not shown exactly as they had happened earlier in the film. They were all a little exaggerated as usually happens in a kid's mind.
- When Kevin is at the counter of the grocery store, the clerk scans a bag of toy soldiers and looks at Kevin. He says "It's for the kids". But when the clerk asks, "What about your brothers and sisters?" Kevin replies, "I'm an only child." While this seems that Kevin is stumbling over his lies, he is not. He is at the grocery store alone, buying "grown up" things like orange juice, milk, bread, toilet paper, and laundry detergent. He is also reading a tabloid and discussing the quality of microwave dinners just as an adult does. When the cashier scans the toy soldiers she looks at him questioningly. Kevin makes a joke saying they are "for the kids" referring to his own children. Obviously he does not have children, but his purchases and actions make him seem grown up.
- When Kevin calls 9-1-1 to report that robbers are in his house, he uses a phone that says "Pacific Bell," which isn't available in Chicago. They would not receive service from Pacific Bell, but Pacific Bell does sell phones which can be used anywhere with any service.
- There is no explanation about why Old Man Marley had a bloody rag on his hand while in the store or a Band-Aid on his hand when he and Kevin shake hands in the church. However, the novelization by Todd Strassman explains that when he was in the store, he accidentally cut his hand on the blade of his shovel. Even without the novelization's explanation, it is still likely that he had blisters on his hand caused by shoveling snow which burst, necessitating the bandage.
- The house loses power in the night from the falling tree branch. This causes them to oversleep. The power gets restored before they leave, obviously, because we see the parents' alarm clock showing 12:00. The timers for the lights would be affected, and the lights would not turn on at the same time that the burglars were expecting. However, Kate asks Peter on the plane if they set the timers on the lights. Peter says "I did." This indicates that they did in fact reset the timers.
- When the pizzas arrive, the guy says the cost will be $122.50. In the kitchen, however, Peter says "Ten pizzas times twelve bucks.", which would indicate the pizzas would cost $120.00. For the pizzas to cost $122.50, they would need to cost $12.25 each. However, the extra $2.50 was most likely added as a delivery charge, or an automatic gratuity considering the size of the order.
- In the beginning of the movie after Peter realizes he will not be able to shave in Paris without a power adapter, Kate tells him to grow a goatee. This would be impossible, since a goatee would still require shaving part of your beard. However, it seems like Kate is merely making a sarcastic joke while Kevin is bothering her.
- When Kevin makes the sign of the cross before eating his dinner, he makes it what would appear as wrong, touching his right shoulder first - however, some eastern Catholics, such as Byzantines, bless themselves in this manner.
- When the alarm clock turns off because of the power loss, we can clearly see that this Panasonic clock has a battery back-up feature, which means that even after the blackout, it should have still worked. However, a battery may not have been installed or may have been dead.
- Kate was unaware Kevin was missing until the family are in midflight on the plane. Given the family would have to go to the flight desk then security, Kate should have discovered Kevin was missing at the airport. But Peter threw away Kevin's ticket along with the paper towels (they were red, like the ticket) in the kitchen scene, so there are 10 kids and 10 tickets.
- Before Kevin's family goes to France, a repair man tells Kate the phone lines will take a few days to get fixed yet Kate manages to phone the police when the family arrive in Paris which should be impossible. The police Kate phones was probably located some distance from their home, and the phone lines there were not damaged.
- In a scene where a police officer arrives to pick up Kevin and bring him to his family, he kept knocking until he decided no one was home. In reality, a police officer would not assume anyone is home when Kevin was in the house as they would actually get him to come out of the house so that they could bring him to his family.
- When Kevin is sliding down the steps the toboggan is lined-up with the stairway, when he goes out the door, the toboggan is now lined-up with the doorway. He should have just crashed into the wall and not gone out the door.
- After Marv is hit with an iron, a wrinkle can be seen in the mark on his face revealing that the iron print was actually a plastic sticker. It can also be seen later when Kevin puts the tarantula on Marv's nose.
- When the McCallisters are leaving in the morning and the neighbor boy is speaking with the van driver, he is mouthing the driver's lines (the first time the driver speaks).
- The iron Marv pulls down has round holes, but the imprint it leaves on his face has rectangular ridges rather than round. Since the ridges on his face are caused by the holes in the iron, the shapes should match.
- When Marv slips at the bottom of the stairs near the basement door, the "ice" moves underneath, being a sheet of Plexiglas.
- As Kevin flies through the air outside the front door after he sleds down the stairs, you can see the rollers on the bottom of the toboggan.
- When Kevin cuts the rope in the treehouse, the rope clearly has far too much slack for even a single person, let alone Harry and Marv, to hang from it.
- Harry's stunt double can be seen when he first slips off Kevin's front steps. It is also the same stunt double in the behind shots as he holds onto the side railing while trying to climb the steps.
- Obvious stand-in for Harry as he walks towards the front door in the side-on shot. This person is much taller than Joe Pesci.
- While Jeff is zipping up his bag as Kevin tells him he never packed a suitcase, you can clearly see a newspaper protruding out.
- When Old Man Marley hits Marv with the shovel, it shows that Marv's body is a mannequin.
- When Kevin is shooting the toys by the rifle into the laundry chute, you can see that the third bullet doesn't hit the mark (the toy) but clearly passes above it (can be seen as a small dot of somewhat metallic color) and yet the toy falls down the chute.
- On the grocery store cashier's register monitor, no changes whatsoever occur during the transaction.
- When Marv is hit in the face with the iron, if you look closely before he falls down you can see that the iron hits him on the forehead, but when he sits up, the iron has left an imprint that covers his entire face.
- Obvious stunt double in the long shots of Kevin swinging across to the treehouse.
- Each time that Kevin leaves his home and returns, he only turns the knob to enter the home. Clearly, he never uses a key. When he knew that the burglars would be coming back at 9:00 pm, he leaves the church, arrives home and runs directly into the house indicating it was already unlocked.
- When Marv and Harry are arguing in the van, they realize they are about to hit Kevin and screech to a stop. But the distance they had to stop was not enough time to avoid hitting Kevin. Nor did the distance shown at first match the next scene.
- When Harry and Marv are climbing across the rope and Harry tells Marv to go back, we see them from behind, then when it cuts to the shot facing them front-on, Kevin can be seen in the background about to cut the rope. If you look closely this is not Kevin, it is his stand-in.
- When Marv is climbing the basement stairs, his bare foot comes down on a nail which then makes him fall off the stairs. However, the shadow of his foot appears next to the nail rather than over it.
- Near the end of the film, as Kevin looks out of the window to see Mr. Marley reunited with his son, a hand holding a camera is clearly visible.
- When Marley is shown hitting Harry and Marv with the shovel, it is a double swinging the shovel.
- In the film that Kevin is watching, "Angels with Filthy Souls", Johnny shoots Snakes with a Thompson machine gun. Snakes is standing in front of a door with a glass window. At the short range that Johnny shoots him, at least some of the bullets would have gone right through Snakes and broken the window.
