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.

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.

I'm not one of these actors who can make a bad script good. Some actors, a script can be terrible, and they can bring something to it and make it really special. I can't.

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

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'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.
