I sometimes think if I had gone to Oxford or Cambridge and looked like a handsome young guy who could be in an Evelyn Waugh novel or something, I'd be a massive movie star. But there's a longevity to what I do. It's more reliable. Someone isn't deciding that I'm the next big thing.

I wasn't one of the ones voted most likely to succeed when I was at drama school, but I persevered and concentrated on the acting rather than going to the right parties and getting the right agent. Eventually, after ten years, it paid off.

There's no great mystery to acting. It's a very simple thing to do but you have to work hard at it. It's about asking questions and using your imagination.

When you're the youngest and the only boy, you get spoilt but you get told you're spoilt so you don't get to enjoy it very much. I was the only man in the house because my parents divorced and my dad moved away when I was 13.

With a face like mine, I'm never going to play a character who conquers the universe, I'm going to play characters who are subject to forces bearing down on them. My career's based on how we are rather than how we wish we were - they get the good-looking boys in for that kind of role.

Mike Leigh taught me about making choices - as an actor, you choose between being honest and clever, and with Mike, it's always about being honest. I learned how to behave on a film set from Jim Broadbent. He was a great example of someone with a fantastic career who kept his feet on the ground.
