When you think of actors who totally morph themselves for their different roles, it's easy to first think of famed Method actors like Robert De Niro and Daniel Day Lewis, but what about Matt Damon? In Damon's lengthy career, he's shed enough weight for roles to actually become sickly and emaciated, and bulked up to be street-fight-ready in this summer's Elysium. Whether he's well-coiffed and spray-tanned or accurately portraying a South African champion athlete, Damon convincingly commits to every role, changing his body, his physical training, his accent and even his complexion. Take a look back at Matt Damon's greatest physical transformations, from Elysium to Courage Under Fire.
