15. Peter Weller
Every cult film fan loves Peter Weller. He starred in the hugely popular The Adventures Of Buckaroo Banzai Across The 8th Dimension, which led to him being selected by David Cronenberg to play William S. Burroughs in his adaptation of Naked Lunch. Yes - the guy played the Beat Generation's most controversial author - it doesn't get much more countercultural than that. But there is, of course, one role for which Weller will always be remembered. It's just sad that, cult fans aside, most people recall the character rather than the actor; Weller was the man that brought RoboCop to life. He managed to make a prosthetically-covered robot in a dystopian future into a sympathetic and complex figure in what remains his most famous role. If things had been different, RoboCop would have been the springboard for Weller's career. He would have been excellent in many of the superhero films and thrillers of the 1990s, but his chance seemed to pass him by. Still, at least some of his roles are remembered beyond the realm of cult fandom.
