The late Roger Ebert once observed that there was no better way to hook an audience than to show a smart character being smart. Most of the time, that applies to the story's protagonist. But in the action classic Die Hard, it's the villain who shows the audience how smart he is. Hans Gruber -- played by Alan Rickman in the role that made him a star -- orchestrates a brilliant scheme to steal hundreds of millions of dollars from the Nakatomi Corporation on Christmas Eve, and comes within one off-duty New York cop of pulling it off flawlessly. He's an indispensable part of the film's magic, and one of the most memorable villainous performances of all time.
