Christian Bale's Transformation for "The Machinist" (2004)
One of the most dramatic physical transformations in cinema history, Christian Bale lost 63 pounds (approximately 28.5 kg) for his role as Trevor Reznik. His weight dropped to an extremely dangerous 120 pounds through a strict diet of only coffee, an apple, and one can of tuna per day.
After filming The Machinist, Bale had just six months to regain mass and build muscle for his role as Bruce Wayne in Batman Begins (2005), where he successfully reached 220 pounds.
