What audiences may not know is that Tom actually did many of the stunts himself! In Mission: Impossible II, Tom slides down the edge of a mountain and dangles off a ledge with nothing but his bare hands to keep him from falling.
"I really wanted to give the audience a thrill," Tom says. "We spent four days doing that scene, and I was on the mountain with just a thin wire kind of holding me as we were doing it. It was really exciting."
