The negative about acting is that you have to spend a great deal of time away from your friends and loved ones, but it's not like working a 9-5 job and only having two or three weeks off a year. I may not have seen my girlfriend for two or three months, but then we can spend two or three months together solidly.

I think we can't feed the amount of people that are on this planet the way we are doing it.

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

Some people can very easily switch off and be guilt free, not that what I'm doing is about guilt, but they can completely disconnect and not care because it doesn't affect them. I've always really cared about what happens and felt a certain responsibility.

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 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 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.
