The movie is so fun. I've done period pieces before but nothing with this twist. And the movie is just full of such wonderful people, such young actors - people like Matt Smith that I've been friends with for a while.

As a kid, I used to run around our garden waving a stick and pretending to be a million different people. That's why I became an actor, 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.

Being blinded by young love. I remember the feeling, when I first fell in love - you don't see the world the same way that other people see it. You don't see the same boundaries.

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.

Each character you play has its own set of characteristics, for want of a better word.

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.
