I'd imagine a great date would be to go skiing. Imagine going skiing. Go ski with someone, if they can ski.

[London is] one of the best cities in the world. There is just so much culture there and so much history and so much diversity. It's just a perfect place to grow up. I studied at the Guildhall every Saturday so I'd always be in town every weekend doing that. I was kind of a city boy really.

Have you seen Cowspiracy? It takes a lot more land to feed a meat eater than to feed a vegan or a vegetarian. It's something I'd love to get into but it's very hard to persuade people to stop things they've been doing for a long time. So maybe it needs to start with the next generation. Everyone needs to raise their children with a bit more responsibility.

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.

What is life unless you're having a good time? I don't really have a plan; I just try to dip my toes in different ponds.

It's really important to take time for yourself because if you don't know what it is like to be a real person and spend time with a sense of normality, how can you play normal people in films?
