Funny scene in a funny movie. A very young Macaulay Culkin is chatting with his Uncle Buck (John Candy) and quizzing him to see what he can find out above him. Both are so serious but Buck is happy to answer his nephews question and he does manage to ask him 11 of them.
Uncle Buck's Director and Writer, John Hughes, saw the potential of Macaulay and after the release of Uncle Buck, he wanted to create a new vehicle for him which happened to be Home Alone. So, if it wasn't for Macaulay being cast in Uncle Buck we wouldn't have two holiday successful films Home Alone and Home Alone 2: Lost in New York.
Also, we wouldn't know that someone could be named Macaulay.
