Going over to Lesvos in Greece and meeting some of these poor refugees who have just made the treacherous sea crossing opened my eyes in a way I can't even being to describe. It's put a fire in my belly to really try to do something, the little I can do.

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.

I suppose to a certain degree. London's my favorite place on the planet and the reason for that is its fantastic diversity.

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 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've spent a lot of my teenage years working on sets. I've missed out on more than just playing rugby, but I think I've managed to keep my feet on the ground and keep my friends around me.

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.
