I think there's such a thing as a performance gene. If it's in your DNA it needs to come out. For me, it originally came out through music, then segued into acting and came out through there. I always needed to get up and perform.

From a very young age I had an ambition to be a musician, and to do that professionally. That's what I pursued until I was about 20, playing in bands that were taken pretty seriously at that stage.

All I've tried to do as an actor is follow the good writing. That's been my main drive. It's not always possible, so when you do come upon it, like when I came upon this, you realize pretty quickly this is something you need to be involved with.

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

I don't have a burning passion to live in America per se but I would certainly like to work there.

I guess because theater's so ephemeral and it's gone. You make this nightly contract with the audience and you redraw that contract for the next night, whereas film and television, it's forever. I suppose it's always about adopting personas, never about being yourself. I think they call it a "shy man's revenge."

I never make a distinction between doing a film in Hollywood or doing a film independently. It's just the story. It's always the story for me. The constants are that it should challenge me and I shouldn't repeat myself. And the story should always be a story worth telling.
