Movies that permanently damaged actors' bodies

Gerard Butler in Chasing Mavericks (2012)
Gerard Butler seems to specialize in making movies that could kill him, but he never imagined a wave would bring him the closest he'd get to death. Chasing Mavericks is a surfing film about a young man who's insistent on riding the most dangerous waves. It required a lot of real surfing for the cast, including Butler, who had limited experience but was excited to learn. In the end, Butler did most of the surfing himself, only using doubles for the biggest of waves.
