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.

My idea is just to do something different each time; the next thing I do has to be completely different to the thing I've done before - that's what I try and do, because you know, I'm an actor, not a film star.

I used to do a lot of comedy. I don't know what happened. I think it's my face.

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.

I have friends who are leading men, and they're only ever allowed to play leading men of a certain type. But as a character actor, there's a wider variety of projects available. On the big Hollywood films, all they care about is having their lead in place, so it's actually easier for someone like me to slip in. And I'm happy to do so.

I want to be respected as an actor. There's my ego. But I don't have a great need to be liked by an audience.

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.
