Christian Bale
The actor is known for transforming his body to fit the character he is playing. This has meant both increasing and decreasing his weight. Doing this has gained him kudos for critics of his work. Most recently, he dropped a disturbing amount of body mass, to film The Machinist, and then retransformed into superhero Batman.
