Being a famous actor requires a lot of work. Memorizing lines is only part of it. For an actor (or actress) to truly deliver in their role, a lot of time and effort has to go into it. Every character has his or her own emotional reactions, voice inflection, and of course look. However, while most movie and television sets have hair and make up crews to help transform the actors into their characters, occasionally actors will take that transformation to another level. Some of these transformations involve very extreme body changes that take lots of time and commitment on the behalf of the actor.
Academy Award winning actor and talented musician Jared Leto has undergone multiple make overs for his film roles, some more dramatic than others. In 2000, he dropped nearly thirty pounds for his role in Requiem for a Dream. Seven years later, the slim actor put on 67 pounds to play John Lennon’s murderer, Mark David Chapman in the film Chapter 27. More recently, he again lost around 30 pounds to land his award-winning role as a transgender woman in Dallas Buyer’s Club.
In order to play a soldier in the movie Courage Under Fire, Matt Damon reportedly lost so much weight so fast (around 40 pounds in 100 days) that he had to take medication to correct it even months after filming ended. He has also gained weight for roles such as in The Informant, and muscle for Elysium.
It is reported that Eric Bana gained 30 pounds in a single month in order to play his character in Chopper, while his character of Hector in Troy required him to bulk up with muscle.
