I was obsessed with Batman as a kid. I did the film in part just to be near the Batmobile. But I also think [director] Christopher Nolan made a very fine, intelligent film.

I think audiences are a lot more intelligent than what we give them credit for and understand that an actor is playing a role and that doesn't mean he can't play different types of roles.

I'd love to work in America, some of my favourite films come from America.

If you behave like a celebrity, then people will treat you like a celebrity, and if you don't, they won't. There's not much to write about me in the tabloids.

In terms of trying to improve as an actor, for me it's always important to return to the stage. After doing a piece of theater for a prolonged period, I can think I must have surely improved in some way as an actor - you must be fitter than you were prior to doing it. For me, theater is very, very important in keeping things fresh and dangerous.

At the moment I'm doing this space movie, so I'm obsessed with physics and space travel. I know three months down the line it's gone. Then I'll be able to superficially say stuff about space.
