I want to be challenged, I want to keep challenging myself - whether or not it's changing yourself physically or just pushing yourself to a certain extreme. I get bored quite easily so I like to keep my mind entertained by challenging myself.

When I do go to L.A., it is usually for a reason - to meet with a director or something - but I'm always so happy to go back to London.

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

Obviously, you never shoot the scenes of a film in order or only very rarely.

I love Leonardo DiCaprio. He just makes really great films with great directors. He has great relationships with directors but also has a great social awareness. I think he balances his work with his responsibilities to his world, the environment, things like that very well. I'm very impressed by him and I admire him a lot. And other actors like Joaquin Phoenix, I just look at him and marvel at his unexpectedness, just his work really.

I was lucky enough to get a very good agent at the age of 15, and got my first film when I was 16, so it's been rolling on since then.

I live alone so I always just eat out. When I'm in another relationship, then maybe we'll start cooking together.
