Christian Bale — The Body-Horror Method Actor

Bale lost 63 pounds for The Machinist (2004), then gained 100 pounds of muscle in six months for Batman Begins (2005). He then gained 43 pounds of fat for American Hustle (2013), got shredded again for Exodus, then gained 40 pounds to play Dick Cheney in Vice (2018). His body has been through more transformations than most people's wardrobes. Each role earned critical acclaim — The Machinist is a cult classic, the Dark Knight trilogy grossed $2.5 billion, and Vice earned him an Oscar nomination. His body is his most expensive special effect.
