Movies that permanently damaged actors' bodies

Anne Hathaway in Les Miserables (2012)
Who knew it was so dangerous to play a doomed singing prostitute? Anne Hathaway won Best Supporting Actress for Les Miserables in 2013. There was little danger of her breaking any limbs, since the depressing French musical isn't known for its big dance numbers. But Hathaway had to make great physical sacrifices anyway.
