The Machinist - Christian Bale

"The producers of the film claim that Christian Bale dropped from about 173 pounds in weight down to about 110 pounds in weight to make this film. They also claim that Bale actually wanted to drop down to 100 pounds, but that they would not let him go below 120 out of fear that his health could be in too much danger if he did. His diet consisted of one can of tuna and an apple per day. His 63-pound weight loss is said to be a record for any actor for a movie role."
