10 Movie Actors Who Can't Escape Their Most Iconic Role

8. Thomas F. Wilson - Biff Tannen (Back To The Future)

Although the part of dim-witted bully Biff Tannen was his breakthrough role Wilson's career, he has been so blighted by inquisitive Back to the Future fans asking the same cycle of questions about the time-travel trilogy that he ingeniously resorted to carrying around copies of a pre-prepared answer sheet that he now hands out when the need arises. He even penned a song entitled "Biff's Question Song" that continues to feature in his stand-up comedy routine. Despite being the primary antagonist of the series, playing four separate incarnations of Biff and his ancestors across different time periods, he was a hit; a character that audiences loved to hate. While Biff remains ever-popular, Wilson has never acted in anything noteworthy following BTTF and mainly specialises in cartoon voice-overs.
