During the London press junket for The Dark Knight in the summer of 2008, Christian Bale was infamously accused of assaulting his mother and sister at the five-star Dorchester Hotel. Six months later, a recording of Bale's rant on the set of Terminator Salvation was leaked, and the star's anger began to define him. But beyond his notorious temper, Bale, an Academy Award-winning actor for his role in The Fighter, is known for his ability to physically transform himself for roles in American Psycho, The Machinist, and as one of Hollywood's most revered and bankable characters--Batman.
