Shia LaBeouf

Shia LaBeouf spent three seasons as the title character of the Disney Channel's Even Stevens (2000-2003), then made his mark on the big screen as the young star of Holes (2003, with Sigourney Weaver). LaBeouf then moved away from the family friendly roles that brought him fame (and a Daytime Emmy) to more adult roles in I, Robot (2004, starring Will Smith) and Constantine (2005, starring Keanu Reeves). To make sure audiences knew he had grown up, he played a potty-mouth in the coming-of-age drama A Guide to Recognizing Your Saints (2006, with Channing Tatum) and a naked drug addict in the star-studded feature Bobby (2006, about the day Robert F. Kennedy was assassinated). Star of Disturbia (2007, with Carrie-Anne Moss), Transformers (2007, with Megan Fox) and Eagle Eye (2008), LaBeouf also co-starred opposite Harrison Ford in the 2008 film Indiana Jones and the Kingdom of the Crystal Skull (with Karen Allen). He also starred in the 2009 sequel Tranformers: Revenge of the Fallen.

Extra credit: LaBeouf has a tattoo reading "1986-2004" -- the years from his birth until he turned 18 -- on the inside of his right wrist. He told the Associated Press in a 2007 interview, "I feel like you forget a lot of your childhood so I put the timeline on my wrist. I just don't want to forget the childhood I did have."
