I'm used to being in front of camera and knowing what to think. But if you're asking me to be me, I get very self-conscious. My job isn't to be me. Being an actor, people think you can do a eulogy at a funeral, a speech at a wedding. I find all that very nerve-racking.

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 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 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've never played a gay character on screen, so that would be interesting. I've never played a gay character, and that would fascinate me because I'm not gay, so that would interest me.

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 come from a place where there's violence and inarticulacy. I worked in a pub from the age of 12 or 13. I used to see people smashing glasses over each other. I was never tough. I was scared of them.
