I grew up in London, and that's where I spend most of my time. Unless I have a really good reason not to be, I'll always be in London.

Every year I look at the 'GQ' Best-Dressed List and have thought what an honour it must be to be included. I couldn't believe my eyes when I saw my own face in there.

I was lucky enough to get a very good agent at the age of 15, and got my first film when I was 16, so it's been rolling on since then.

I've had friends who have come away who've said, "I shouldn't have become such close friends with the director." You always want to get on with the director, but I personally prefer a relationship where you respect them - you get on really well with them, but they're boss, as it were. It's about trusting your director, for better or for worse. They're the one's seeing what's coming out on the monitors, so you have to try and trust what they say.

I love Leonardo DiCaprio. He just makes really great films with great directors. He has great relationships with directors but also has a great social awareness. I think he balances his work with his responsibilities to his world, the environment, things like that very well. I'm very impressed by him and I admire him a lot. And other actors like Joaquin Phoenix, I just look at him and marvel at his unexpectedness, just his work really.

I actually wanted to be a jazz musician first. My grandparents introduced me to Louis Armstrong. I loved Louis Armstrong so I took up the trumpet and just did that every day and practiced that.

I dreamt of being an actor ever since I was young.
