Christian Bale in The Machinist
Christian Bale’s weight loss for his role in The Machinist is one of Hollywood’s most famous incidents where actors put themselves in danger for their job. For this psychological thriller, the actor had to lose no less than 60 pounds in order to fit the character of an insomniac.
What’s even more crazy is that he had to gain back all this weight and more within six weeks, in order to fit his next role as Bruce Wayne in Batman Begins
