I'm definitely a frustrated musician, though it's more in terms of wishing I was a better guitar player and songwriter. But I've never regretted becoming an actor instead. I think it's been a more pure form of self-expression for me. I luckily found something that I could aspire to be good at, whereas I never... I think I'd never quite reach that level of artist that I enjoy in the music world.

And, for any performer, to be able to go deep into character is fantastic. In film you only get to do that if you're the leading character. But in television you get 18 hours to really test the audience and take them to the edge of how far they will go with this character. I can step over this line and I love that.

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.

Having started out in theatre, I feel an impulse to do it as much as I can

I don't care if people perceive me as always selling out because I'm doing a studio picture. For me, the whole thing is you should be diverse in your choices; that's the beauty of being an actor, you should be able to do that.

My wife can see always how a part affects me personally because she has to live with it.

I started off in theater; I did exclusively theater for four or five years. In the last few years, television has come along but I can still make film. I feel very privileged that I can move between them.
