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.

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 consciously decided not to be a 'London' actor. Those gangster movies made a lot of East End actors think they were movie stars. And I was very aware that they were going to go out of fashion.

I was brought up in a house full of women; the first time I realised no one was interrupting me was when I was on stage - that's probably the subconscious reason I became an actor.

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?"

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.

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.
