As a working-class actor, leaving school with no qualifications, being a printer and then becoming an actor and then working with people who to a certain extent had had a leg up. I never had that advantage. It's less an artistic need to express myself and more a need to prove myself.

I wanted to work with Bryan Singer because I like his films.

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.

I've got four kids to feed and a wife to provide for. It's a worry but a great responsibility as well and one I relish.

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.

I went swimming the other day and my wife was watching and she said: "You know, it's funny, it's when you've got no clothes on, no one recognises you." I said: "What are you saying? That I should do more love scenes?"

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.
