As a man - no longer a teenager that can play those really young roles, but as a man - I think I've only just got good in the last three or four years. I only watch my old films because, as someone who wasn't trained, that's how I look at my mistakes; I see something and I go, "Well, that's not good," and I learn from my mistakes. Same with the writing and same with the directing.

I'm a nice guy to anyone I meet, until they show me they don't deserve niceness. I'll turn very quickly. But I'm pretty pleasant overall.

When I write a project, it might be something that I want to do and then when I look at it, I'm actually like, "I kind of don't want to direct it." I don't know why, I still love it enough for it to be made and to support it, but I don't want to direct it. I just give it to other directors and they do a good job!

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.

I think now you see a lot more British films from the perspective of, I guess what would be considered "new" British people - people of color, Asian people. I think that's what's happening now, whereas 20 years ago it couldn't happen because it was still predominantly, "British film is about middle-class white families and what they do."

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

What I want to do is make things that I think people want to watch. I'm a film fan, so I think I'm in touch with other film fans and that they might want to watch stuff. The other reason I really don't care is because no matter what you do in life, no matter what you wear, or what you say, people are going to like it or they're not. And that is all. Everything, down to the socks I chose today - people are going to like them or they're not and there's nothing you can do about that.
