Johnny Knoxville is well-known for doing the CRAZIEST stunts, especially when you look back at his "Jackass" days.
He is starring in a new film called "Action Point" which is set on a dodgy theme park which doesn't care much at all about safety standards. Although it sounds pretty epic, and we are already keen to watch it - Knoxville claims that he got hurt more during the film, than in any "Jackass" film ever. That's a pretty massive claim!
