How much would you change your body for a job? Some celebrities take their job as actors and actresses so seriously that they willingly undergo extreme physical transformations to play particular characters. It's not uncommon for a celeb to have to lose weight or bulk up for a movie role, but some go to the extreme and lose an unhealthy amount of weight. Here are 11 of the most dramatic celebrity weight losses for movie roles.

Matthew McConaughey has been causing quite the stir in recent months as he undergoes a 30-pound weight loss to play a man with AIDS in The Dallas Buyer's Club. "I should not look healthy by the time I'm doing this," he said. "It takes a while for your body to understand that it has to feed off of itself and that you’re not going to give it something else from the outside."

Mila Kunis lost 20 pounds for her role as a ballerina in Black Swan. At the time of filming, she weighed just 95 pounds. "I had no shape, no boobs, no ass... All you saw was bone," she said of her appearance.
