Frank McCallister is Kevin's uncle and brother of Peter and Rob McCallister. He is married to Leslie and is the father of Fuller, Tracy, Sondra, Brooke, and Rod. He has a highly eccentric attitude towards others. He was seen in the first two Home Alone movies.
Home Alone
In the movie Frank drives down to Chicago from Ohio with his wife Leslie and children Rod, Sondra, Tracy, Brooke, and Fuller to stay at his brother Peter's house for the night and then the next day fly with his family and Peter's family to spend Christmas with his other brother Rob and his family in Paris.
In the beginning Uncle Frank doesn't allow his youngest nephew Kevin to watch the movie that the older kids get to watch. Kevin complains to his mother Kate about it and says "It's not even rated R. He's just being a jerk". However, Kate doesn't do anything about it.
When the pizza delivery guy delivers the pizza, Uncle Frank takes it from him and learns it's $122.50. Frank replies that the house belongs to his brother Peter and that he'll take care of it. In the kitchen when Peter informs Kate that the pizza is $122.50 Kate asks "For Pizza?"
Frank replies " Ten pizzas times twelve bucks". When Leslie asks Frank if he has the money, Frank says "Travelers' checks". Kate replies with "Forget it Frank. We have cash". When Kevin gets into an argument with his older brother Buzz over pizza, Frank accidently gets soda spilled on his pants and he accidently pushes his chair against his son Fuller, who is rescued by Leslie. Frank wipes the spilled soda off of his pants before he looks over at his nephew Kevin and says "Look what ya did, ya little jerk!" Kevin's mom sends Kevin up to the third floor for causing the incident.
During the night the power goes out, and the McCallisters wake up late and hurry to the airport. Frank is seen carrying Fuller and running to the gate. They make their flight and Frank asks the flight attendant for champagne and also asks if it was free, to which the flight attendant says that it is. On the flight when Frank looks at his champagne glass, he first taps it with a fork before remarking that it was real before suggesting that Leslie put them in her purse, to which Leslie disagrees. When Kate realizes that they've left Kevin home alone Frank calls it horrible and asks Kate if it makes her feel any better he forgot his reading glasses to which Kate, Leslie, and Peter all glare at Frank. When the plane lands Kate rushes to a telephone to call the Chicago Police and asks Frank to call everyone on the cell phone to which Frank does but doesn't get anyone. With no more flights going out to Chicago Kate decides to stay at the airport while Peter and the rest of their kids go with Frank and his family to Rob's apartment. That night at Rob's apartment Frank finds shrimp appetizers to which his sister-in-law Georgette tells him that they're for later but he ignores her and serves them to his many nieces and nephews.
