Alan Rickman's portrayal of Hans Gruber in 'Die Hard' made for one memorable foe. In the first film of the series, Gruber leads a team of criminals to take over the Nakatomi Towers as if they're leading a vengeful terrorist attack, but it's all just a sophisticated set-up for a major heist. Who the hell uses a terrorist attack as a cover-up for a theft operation? Oh, right -- a really, really bad dude.
