He had to lose 63 pounds in order to portray the insomniac machinist
This method actor has been on our list a number of times. The press tour Christian Bale conducts in the character’s accent is no exception. He’s also very expert at disguising himself. Christian Bale lost 63 pounds to portray Trevor Reznick, a sleepless machinist. Rumor has it that the actor had intended to lose up to 100 pounds, but the producers forbade him from doing so.
A can of tuna, an apple, black coffee, and water was Christian Bale’s daily diet while undergoing this astonishing change.
