- "Kevin! You spent $967 on room service?!""
- ―Peter to Kevin
Peter McCallister is the father to Kevin, Buzz, Megan, Linnie and Jeff McCallister. He is very protective of his kids. In the novelization for the film Home Alone, he is a successful businessman. His brothers are Frank and Rob McCallister. Peter is the husband of Kate McCallister.
In Home Alone, Peter is wondering how he is supposed to shave in France. In France, he tries to call their neighbors, including the Murphys, asking about Kevin and his whereabouts, and then tells his brother, Frank, that he could not find anyone; they had all gone shopping, and that no one was home for the Christmas holidays. Later, after the family gets home on Christmas Day, after hearing that Kevin had gone shopping and got some milk, eggs and fabric softener, Peter remarks, "What else did you do while we were away?" Kevin replies that he just hung around. Peter then finds Harry's gold tooth and wonders what it is.
Home Alone 2: Lost In New YorkEdit
In Home Alone 2, Peter is looking for the batteries for a camcorder, finds them and then accidentally resets the clock. At the Christmas pageant, when Buzz pulls a trick on Kevin using the candlesticks, Peter, along with Kate, Leslie, the conductor and the piano lady, is not laughing.
Later, when Kevin tries to walk out of the family meeting, Peter threatens to send him to the third floor (like the previous film); however, he goes by himself.
Then, after the bill from Kevin's original stay at the Plaza Hotel comes, Buzz reads it, then after saying "Merry Christmas indeed", calls out "Oh, Dad!"
Peter comes in, and then two seconds later, yells "Kevin! You spent $967 on room service?!"
