Damon plays ripped factory slave Max De Costa in this summer's Elysium. He approached his role in the dystopian sci-fi thriller by building more raw muscle, transforming his Behind the Candelabra frame to be ready to fight an army of droids. He also shaved his head and covered his body in tattoos that seem like they've always been there. Director Neill Blomkamp was so specific about how he wanted Matt Damon's body to look that he found a picture of a man with rock-hard abs, taped Damon's face to it and sent him to a trainer for four-hour-a-day workouts, as Damon explained to Variety. The result: Damon looking awesomely badass, a far stretch from any of his previous roles.
