I don't like doing things that are too easy.

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

I think that's important for all ages, to not be afraid of being an individual. I grew up on my own, as an only child, so early on I think I was quite capable of making decisions by myself and being an individual.

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."

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.

People can criticise me all day long. It just washes off me. You might as well be talking to a wall.
