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've always had a social awareness. My favorite channel on TV is BBC News 24. For a while, I had to have it on repeat in my house. I've always been interested in what's going on in the world.

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.

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.

Nothing's been changed overnight. It's like watching your cat grow: you see it every day, so you don't really see it change, you wake up one day and it's a bloody great thing. Your friends come round who you haven't seen for a couple months and they're like, "Oh my god, your cat's grown so much again." And I'm like, "Has it?" But when you're living it... I just find that my life has subtly changed bit by bit, so I don't ever really notice it too much.

I'm just trying to choose interesting, quirky projects or things with interesting directors or just movies that have a lot of people I like attached to them so I know I'm going to have a good time.

I had friends who ran off to become ski instructors or worked in cool bars, and I often envied them, but I know I'd quickly become bored with that kind of life. I always need to push myself.
