What would I like? Some very silly comedy where I don't have to think about anything, but it could be a lot of fun. And if it's not that, then I'll want to be involved in something where it's like, you're really dredged up to the neck in emotion, where it's as exciting as the premise of Battlestar.

Film and television as a medium has only very recently begun to be taught at the great drama schools in the UK. When I was at drama school in the UK, I was there for two and a half years, and we did one week of television and film. It's right before you leave. It's like, "We've taught you Anton Chekhov and William Shakespeare, you are likely to be in a washing-up soap-liquid commercial."

Anybody who has political ambition has an Achilles heel.

I was desperate to do more TV and film. Because I considered myself to be a theater creature. A theater animal. I was convinced that I was going to be onstage for the rest of my life. Because it's something I can really do. I thought I was pretty good at it, and it's kind of stupid, but I was concerned that people would go, "Oh yeah, he's very good onstage, I'm not sure he can do television."

I think it was in my second week that I auditioned for Battlestar. I was very "Oh gosh, I want to be in television, I want to be in something, but I don't know if I want to be in this."

I never talk about filming until I'm actually on the set and I've got the job, because otherwise - "Oh yeah, I'm going to be so busy," and then you're going to see me in McDonald's in two months.

Rather than, as an actor, I want the audience to like me, I'm going to smile beautifully and I've got everybody's sympathy - what about showing the moments when somebody is unbelievably petty? Or really selfish? The faults, the little things, those are the things that interested me about playing the character.
