If you're suddenly doing something you don't want to do for four years, just so you've got something to fall back on, by the time you come out you don't have that 16-year-old drive any more and you'll spend your life doing something you never wanted to do in the first place.

I wanted to go and explore the world, I guess. And I suddenly thought well, I'll just do it.

I believe that unless it's a scene where I'm alone, then of course I could do what I want but I think good acting is about what happens between people, not on your face and my face.

It is always a nice feeling when you are challenged by a scene and you walk out of trailer and you go on set going I don't know. And then half an hour later you're walking back.

A tent, a roll mat, a little bit of food, a bit of petrol in your tank and a vague idea of where you're going and that's all you need.
