The further you get away from yourself, the more challenging it is. Not to be in your comfort zone is great fun.

I had the privilege of being able to choose, or at least have the opportunity to work at, being anything but an actor.

[on Martin Freeman playing Bilbo Baggins] It was great. I got to hang out with him, and I kept a straight face for a bit and then I started giggling because I know Martin, I don't know Bilbo. For Martin to be sitting there playing Bilbo is amazing. He's going to be amazing, he's going to be fantastic in this film.

I want to do it all. I want to climb mountains, go through jungles, fight wars in space, get the girl, shoot the bad-guy full of lead, have all the zippy one liners, bulge muscles out of a singlet, drip sweat and blood on screen, all of that.

I've always wanted to play a spy, because it is the ultimate acting exercise. You are never what you seem.

I have actual acting scars.

I've been very lucky at what's happened in my career to date, but playing something as far from me as possible is an ambition of mine - anything from a mutated baddy in a comic book action thriller, to a detective. If anything, I'd like Gary Oldman's career: he's the perfect example of it. I've love to have a really broad sweep of characters - to be able to do something edgy, surprising and unfashionable.
