26 Movie Stars You Forgot Were on TV

It's so hard not to think of Robin Williams as Mrs. Doubtfire, isn't it? Before the late comedian starred as the infamous nanny in drag or in any other films like Good Will Hunting, Aladdin, and Jumanji, he charmed audiences as a quirky alien named Mork on the sitcom Mork & Mindy in the early '80s. Robin made a triumphant return to the small screen in 2013 opposite Sarah Michelle Gellar on the CBS series The Crazy Ones.
