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.

One of the biggest things I used to struggle with was about things like going on holiday. Whereas all your friends can talk about something and plan something all year long, I know that I'm probably going to be away and I'm going to miss all of it. If a job comes up, you just can't be there.

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.

I would be the last person on earth to complain about what I do - I feel very fortunate and I know there are a million jobs in the world that are much, much harder - but it's not always an easy or glamorous thing to do, that's for sure.

I wanted to become an actor. I went to Guildhall School of Music and Drama, which is one of the main drama schools in London where you go when you are older. But I was doing the junior one when I was a kid. And some friends there had agents. I was fourteen and I was like, "I want an agent! It sounds awesome!" I had no idea what that was. I thought those guys looked like men in black. They were hanging around in suits all the time. So I luckily got a very good agent in London and started auditioning. And then when I was 16, I got my first film and I've been working ever since.

More often than not, if you've got a good director and a good script you can't really go wrong.

I don't think I've reached perfection by any stretch of the imagination, but maybe someday I'll become a perfectionist.
