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.

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.

It's a very fascinating thing for an actor to play somebody who is suffering, and you have to express the suffering, but in an inarticulate way and sometimes a dysfunctional way, through violence.

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

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.

The trick to acting is not to show off; it's to think the thoughts of the character. I was lucky because when I started acting, it was doing jobs above pubs. I learned to act in anonymity, so by the time people saw me, I knew what I was doing. I was crap for years, but no one saw me being crap. It's a trade you learn.
