The Math in the Movies Web page (http://world.std.com/~reinhold/mathmovies.html) provides an annotated list of films in which mathematics plays some sort of role. The choices range from the calculus lessons of Stand and Deliver to the mystifying numerology of the 1998 thriller Pi.
Among the notable omissions are several movies featuring the comedy team of Bud Abbott and Lou Costello. Probably most famous for their “Who’s on first” baseball routine, Abbott and Costello made arithmetic shenanigans the basis of a number of their comic dialogs.
