38. 'Tron' (1982)
Jeff Bridges was the original movie hacker … wait, that can't be right, can it? As a former programmer-turned-renegade-arcade-owner in Disney's revolutionary sci-fi classic, he was the very picture of rumpled cool. In fact, when he winds up getting teleported into the video game itself – thanks to a sinister, sentient program that's begun to control it – he's still his jokey self. (It's kind of remarkable just how calm Bridges manages to remain after finding out he's trapped inside an actual video game.) One might even say that he brings the ideal amount of levity to this ridiculous and entertaining scenario. His sense of humor tempers the fact that everyone else in this movie is largely stone-faced, since most of them are not, y'know, human.
