"There was a time [on 300] when three nights in a row people were taken to hospital during the fights. One time I was supposed to turn and hit a guy with my sword and I turned to whack him and he was gone, and then I looked down and he was lying there going [grabs arm], 'Arrgghh,' and he’s broken his arm. And the night before a guy got a spear in his eye. He almost lost his eye; he had to get stitches. It was insane."
