Would you jump off the Great Wall of China for 300 pounds a day? A stunt  person is a man or woman who does all the dangerous bits of acting work in films or on TV.

Actually, I fell forty-five feet into a pile of cardboard boxes! You can't use anything softer than that or you will be brought back into view of the cinema.
