Generally, an indie film in the U.K. is put together much like in the states. We got a tax credit. You sell the domestic rights, which can be quite low, but it's enough to push you over the line. And you get a tax credit on top of that, and then you cobble it together with private equity or gap financing and things like that.

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.

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 couldn't tell you the ratio, but probably for every job you see me do, there would be 20 rejections.

I'd always much rather be second choice on anything because it makes you work harder.

It always seems that the generation below you is getting worse, which is why I had the worst character in the film Adulthood that said it. I don't remember speaking to my elders like that, because you never remember... actually our generation was quite bad because everyone else always seems worse.

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.
