10 Times Actors Completely Transformed Their Bodies For Roles

6. Natalie Portman – ‘Black Swan’ 

Natalie Portman is gorgeous and has a great and slim figure, but she still had to drop extra 20 pounds for the role of an obsessed ballerina in the movie The Black Swan. Her rigorous diet consisted of basically carrots and almonds, and she rehearsed for eight hours each day. “There were some nights that I thought literally I was going to die,” said Portman. Luckily, her sacrifice was well worth it. In 2011, she went home with the Oscar for best actress.
