26 Movie Stars You Forgot Were on TV

The Jennifer Garner we all know and love got her start as CIA agent Sydney Bristow on the ABC action drama Alias. She got to do fight scenes and wear a ton of killer wigs on the show, which ran from 2001 to 2006, and also starred a then-unknown Bradley Cooper. These days, Garner has gotten big-screen success from movies like 13 Going on 30, Pearl Harbor, and most recently, Dallas Buyers Club.
