8 actors who transformed their bodies for roles
From bulging muscles to skin and bones, the physical metamorphosis of Hollywood stars is an art all its own.
Jared Leto for 'Chapter 27'
Rock star and Academy Award-winning actor Jared Leto shocked fans when he put on 67 pounds for his role in the 2007 biopic "Chapter 27." The American star, who portrayed a deranged assassin, says he gorged and force-fed himself to induce his body to make the change. The results, however, placed an immense toll on his health.
"Really, it's a stupid thing to do," he told the UK Guardian. "I got gout, and my cholesterol went up so fast in such a short time that my doctors wanted to put me on Lipitor, which is for much, much older people."
Leto says he was able to shed the pounds by going back on tour with his band and sweating up the stage each night. "I was still kinda waddling around onstage for the first few dates, and eventually it came back off," he added. The actor can next be seen as the maniacal Joker in the superhero film "Suicide Squad."
