I'm obsessive enough about getting fit, it's ridiculous. I'm 40 now, and I've got to stop doing it soon. I have to start getting fat and old!

There's a conscious decision to everything I do.

I'm not James Bond. There's your headline! It's very clear to me that he's the furthest from my character that it's possible to be. It's somebody I play.

It doesn't matter whether you have the happiest upbringing... the young Joe Scot had the most dysfunctional family there could be but it's still a family and it's a really good, strong family. But in spite of that he runs away from home. I relate to all of those things very directly. I hit 40 this year but I still think about being a teenager and hopefully I will for the rest of my life. They are important years.

In many films, as many different characters, I've killed many different people.

Obviously, when I came to do the movie I knew that I was going to have to take my clothes off so I might have worked a little bit harder to keep myself fit. But I think that's the irony of it - you see all these fit and healthy people, and I'm not making any comments on it, but everybody deep down is a f**k up somewhere.

I didn't want to do a zoo show. I didn't want to do a study of someone with mental illness. I just wanted to show someone who was trying to live their life.
