11. Mickey Rourke
Sex symbol from the eighties faded into oblivion in the nineties with drugs, party life and plastic surgery taking its toll. Then he was offered a role of a lifetime, to play an aging wrestler. With a story so similar to his own, and an opportunity to make a comeback he trained religiously and it payed off. He gained a lot weight, but that weight was pure muscle so immediately after his role in The Wrestler he was hired in Iron Man.
