We’re not sure there will ever be a better Batman than Christian Bale, and a lot of that is thanks to his expertise in the martial art Keysi. While he did have a stunt double, his job was often made obsolete by Bale stepping in to do the fight sequences himself. He said of Keysi, which he learned for Batman Begins, "It's a very instinctive kind of martial art. It's not about choreography; it's very much about using your adrenaline and becoming an animal in your fighting style."
While Bale wasn't afraid to stand on top of Chicago's tallest building for a shot, he let his doubles, Buster Reeves and Jean-Pierre Goy, do the jump or take the wheel in the Batmobile and Bat-Pod. He said, “I'm quite happy to admit I'm not up to that level.”
