You have to show the negative to show the positivity that comes from it.

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.

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

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

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

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.

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.
