Movieline interviewed stuntman Garrett Warren, who is Mickey Rourke’s stunt double on Iron Man 2, he also did stunt work in Avatar, and he has a job on Tin Tin as well.

You can read the full interview over there, but here’s the really meaty stuff he let loose about ‘Iron Man 2’:

Iron Man 2 had a double-whip sequence, and I am a whip specialist. There’s not very many of us in Hollywood that do double-whips.Double-whip basically means that you have two whips in your hands. I had brought two whips with me that are made of kangaroo hide that are incredibly well made. You can perform all sorts of tricks and cracks with them.

In the movie, you won’t see those whips. They’ll digitally replace it with other types of whips. I don’t know if I’m at liberty to say what the whips will look like, but they’re going to be these super whips that have an awful lot of power. They can cut through cars, they can do an awful lot of damage. And when the movie comes out, you’ll see that he doesn’t do just whip-cracks and grabbing people. He lays waste to an awful lot of vehicles and street pieces and other things.

At one point, Whiplash had to get hit by a car, and Mickey did the lead up to the stunt, and I did the stunt where the car came in and hit me and took me to the fence. So yes, you’ll see a combination of Mickey and myself. And when it comes to the whip routine, I have to admit, Mickey Rourke did a really good job with the whips. However, the suit was very painful at times. It was this big metal piece that wasn’t very comfortable, so he didn’t always want to do the whip routines every take. So I’d go in and do the whip routines.

It covers the whole body in metal rods, but you are shirtless [underneath]. That was the part that was hard. When you move, it was metal digging into skin, cutting your shoulders, wrists and back and so forth.
