What about your hair and its real stylized look? Was that your idea or was that Doug's idea?
That was my idea. I had a little fight with the producer about it but he finally ended up being okay about it. For me, Roland is this kind of timeless guy. I think he's older than most people think he is but he's still very virile — and kind of indestructible in an interesting sort of way and very strong and dedicated to this war. Doug and I talked about it as a comic book sort of film in a way... [and] I think of characters in comics as being very distinctive in specific kinds of ways. And I think what makes Roland kind of stand out in a group of people [is that he stands] out as a leader. And he wears his hair kind of like a crown. He kind of runs the Paladins. There's a lot of stuff about him that may end up on the DVD and may not. He teaches at a university. He has a closet full of things, like that baton that you see. There's a whole big discussion about that machine being made that holds the rips open so that we can follow the Jumpers through them.

If this film is a blockbuster, would you concede Doug made all the right choices? And if it bombs, will you question why Doug did not put the background in for your character, thinking then that the audience needed that?
I don't know. Most films either make it on marketing or don't make it on marketing. If you market it right, people go and see it. I think there are enough elements there. Most kids don't care about that stuff. [Actors] care about it because we watch films in another kind of way, or we read scripts or we like information. The majority of kids haven't read the books. They might go out and read the books now and get the information that way... But the majority of kids that are going to see it just want to see these kids jump and see them taking stuff out of the bank and look at [Hayden's] nice apartment and go: "Wow! If I could do that, I would have this in my house. And I'd go here and I'd go there." And that's kind of cool. And then they like watching the fight sequences, which are kind of cool too. And maybe eventually somebody will want to know all that other stuff. But the hope is that they get to make all three [films]. I wouldn't blame Doug or anybody else for the success or failure of the material.

So there were loads of fantastic locations but if I look carefully, it doesn't look like you went to that many of them.
Did you look carefully? Because I can tell you, I didn't. I was in Toronto and I had another job, actually, so I had a stop date. So when I finished, my stunt double got to go... And he worked almost three times longer on this film than I did. He went to Tokyo and Rome, Tokyo again. He was back and forth a lot. He had a lot of frequent flyer miles.
