I think the British industry is set up to support British film, if we make films that enable them to support it. If you don't make a commercial film, distributors can't get behind it. If they don't get behind it, the film doesn't do well.

I don't feel that I'm a role model. I'm just me. If people want to look up to me then that's their business. I'm not perfect and I don't consider myself to be a role model. But to be honest, I'd much rather my kids look up to me than look up to some rock star who gets off jail more times than is even funny.

After Kidulthood, I was called in to a meeting and told that I didn't write women very well. I was very annoyed.

I don't think I'm egotistical, and I know what my limits are: I'm a black guy who's probably losing his hair. But I'm happy to play roles that I'm given, and I'm happy to play roles that I write.

You'll never see me in any of the tabloids because I've made a conscious effort to stay out of that. I'm not interested in fame. I'm interested in hard work and letting my work speak for what I do. I've been in high-profile shows but you don't see stories on me because I don't go out and court them.

Bullying isn't about size, it's about intimidation.

I can't always be making "British films". Why should we be making films about corsets and horses and girls learning to drive when Americans send over an event movie and make five or 10 million?
