I grew up in Deptford in south London, and at that time I used to wear toppers, loon pants and tonic suits from shops like Take 6 and Topman. I was a bit of a soul boy, but I had a very eclectic taste in music - I was into James Brown and Bowie; and I was the only kid in the neighbourhood who would also be listening to Chopin.

I don't go to premieres. I don't go to parties. I don't covet the Oscar. I don't want any of that. I don't go out. I just have dinner at home every night with my kids. Being famous, that's a whole other career. And I haven't got any energy for it.

Your own barometer is all you have to go by, and often what makes a good director is knowing when not to say something. On occasions you can find yourself on a film set where the person who is wearing the director's hat is only trying to justify his position.

The thing a drama school can't give you is instinct. It can sharpen instinct but that can't be taught, and you have to have intuition. It's an essential ingredient.

By the way, the Harry Potter series is literature, in spite of what some people might say. The way J.K. Rowling worked that world out is quite something.

The great thing about having been in a lot of make-up, and stuff like that, is that when you're working with someone who's in it, and you've been there and done it, but you're not in it anymore, you feel so good.

I don't think Hollywood knows what to do with me. I would imagine that when it comes to romantic comedies, my name would be pretty low down on the list.
