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.

The BFI recently did a study of the British films that have the most people of color in them in the last 10 years, and in the top 10, three of the films were my films. I've always been a glass-is-half-full person. I've always gone, "If people aren't going to do it, I'm going to do it".

When I wrote 'Kidulthood,' I didn't even know there was going to be a 'Kidulthood.' I just wanted to test myself to see if I could write a script.

I think one thing my mother always instilled in me was a sense of individuality. Being an only child, I never thought I had to rely on anyone. I was never afraid to be alone and I was never afraid to be my own person. So when all my friends were like, "Let's smoke weed," I was like, "I'm not doing it." It wasn't because I was trying to be a rebel or because I didn't like it or I was anti-drugs. I just didn't do it because I didn't want to do it, and if I didn't want to do it, I wasn't doing it. That was it.

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.

When people say to me: "Oh don't worry, if one door closes another one opens..." If one door closes for me, go through the window - I'm not interested in waiting around for people to give me opportunities. I try and make things happen and if I am given opportunities I take them and work harder.

I think most people, no matter their status now, have big screen TVs, because they're the standard TVs now. And so why would you go to the cinema?
