Arnold Schwarzenegger in The Last Stand represents a welcome return the action genre's finest sons. The inclusion of Jonny Knoxville struck fans as a bit odd, but what does it actually take to be Arnie's sidekick? The big man's let us know. 

"The important thing is that you click, that he is as enthusiastic about the mission," Schwarzenegger told MTV News. "He has a different approach to how he accomplishes the same goal as I have. I'm a very disciplined law-enforcement guy, and he's kind of a lunatic," he added, of Knoxville's character. "I've been dying to be on the force my whole life, but I'm a little too mercurial to be included," Knoxville added. "It was the greatest day of my life when I was asked to join the force."

But, you're asking desperately, what the hell do I have to do to be starring alongside the man in the film!? Well not to worry, you just have to fill this certain criteria, and you're in. "All you have to do is gain 50 pounds of muscles, gain a little bit in height and in your acting [abilities]," he advised. "Be able to do the stunts, throw yourself around, be able to fall off buildings, be able to be shot at, all these kinds of things."
