Actors Who Went Through Extreme Body Transformation For a Role

Jake Gyllenhaal, Nightcrawler

Jake Gyllenhaal dropped 30lbs for the movie, ‘Nightcrawler.’  “I made a lot of choices physically,” the actor, who ran 15 miles a day just going between his house and the set, said.In the film, Gyllenhaal plays Lou Bloom, a wild-eyed paparazzo who stalks the moonlit streets of Los Angeles in search of sordid and shocking news. Although no one would call him beefy, the star wanted to look as gaunt as his on-screen alter ego, which meant subsisting on a diet of kale salad and chewing gum while filming the role.
