I grew up in a very small town in Scotland, a little place called Crieff which is beautiful and it's at the foothills to the highlands. It's a very beautiful part of the world. It's a small, I suppose quite conservative place.

It's not my job to try and alter the director's style - he's in charge, and I'll always give him my trust.

I wanted to be an actor since I was nine years old.

There's something that happens where you go, if you're lucky, goodness me, from film to another film to another film. And you can sort of feel that if you step off that treadmill, it might all go horribly wrong and you might never be employed again, you know. And I suddenly thought that that's not necessarily the case. And I also thought we make drama as actors about people in the world and that if you are on that treadmill, you start making films about other films.

I never imagined it wouldn't work out for me. I had that absolute certainty in myself that has seen me through, I think, and my parents were absolutely behind me all the way.

What matters most with any regimen, whether it's to lose weight or stop drinking or smoking, is your willingness to seek help and your desire to say 'no more.

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.
