Gerard Butler says there were an “insane” number of injuries when filming his fan-favorite action hit 300 . The Zack Snyder film from 2006 — which marked Butler’s breakout role, playing the fearsome Spartan King Leonidas — was apparently quite war zone on set.

Gerard Butler recalls the difficulties of filming 300 and how many of his co-stars were being taken to the hospital due to injuries.

Gerard Butler injured himself directly before filming Den of Thieves 2: Pantera, making his on-screen pain all the more convincing. The 55-year-old Scottish actor reportedly filmed much of the high-octane heist sequel with one leg completely out of action.
