Do you do much of your action filming, or do you let your stunt double take your punches?
I let him fall. That's what he's paid to do. I jump off things with my wire on. It's kind of nice to throw Hayden around and do that stuff. But in the end, he's paid to go in there and get banged around. Plus, they choreographed all this stuff so tightly that we would shoot stuff with Doug and then they had a whole unit that just did stunts... I had a fight with Jamie that's actually not in the film that it was me, Jamie, and these two Chinese kids dressed as Jamie. So when I would swing at one, the other one would come from another direction, and I had to do a lot of spinning, turning, moving out of the way. And they would crisscross like he was "jumping" while he was fighting me. And it was pretty fun to do but it was crazy... They hired this one French kid who came in to be me. He was a breakdancer, a street dancer... Jamie sets him on fire, and he has to go into like an airplane spin, do a flip, turn up, and start fighting again. It was all badass. And it's kind of cool when people do that stuff for you.

Have you had much reaction from Star Wars fans at all about working with Hayden again?
Star Wars fans? I haven't looked into that. No, [but] some people wrote some really harsh things about Hayden over the years, especially Star Wars fans or people who hate George [Lucas] in another kind of way cause he made three more Star Wars films that didn't kind of go along with what they thought Star Wars should have been. Some harsh things have been written about him. So yeah, a couple of times I read things like hopefully when they get together this time Jackson will die a better death than he did last time. Or he'll teach Hayden some new tricks — some harsh stuff. Hayden's a good kid. I enjoyed working with him. I'm always amazed at the amount of growth that he's shown from the first time he showed up till now. And we have a level of comfort with each other that kind of works on set. It's nice.

Did you keep the Taser you use in Jumper?
Oh, yeah. I have it at home.

Does it actually work?
Well no, there's no electricity that comes out of it. No, it's not like a real Taser. No, but the blades pop up and out of it. I got that one.
