I'd love to get fat on camera. Wouldn't that be great? I'll tell you what's almost as hard though, getting bulked up, getting that big. Here we are in LA and you see guys walking down the street and everyone looks like Arnold Schwarzenegger. That's really quite grim, if you haven't done it before.

I went to an all-boys school and hated feeling like one of the crowd.

The only mistake guys can make is to try too hard with their appearance. There's something very unmanly about it.

For work, I have to be living in cities, I really cherish the time when I get to be out in the countryside.

Each year we go to the Cannes film festival and I tend to have all my friends pile in the back of my car and we'll drive from London. The poor production company think they're only putting me up and suddenly they've got eight people sleeping on my hotel room floor.

You can be the best actor in the world, but if you don't have that one lucky moment, it kind of doesn't matter. There are a lot of amazing actors who will never get the chance to prove themselves because they won't have that one lucky moment.

The Railway Man was a particularly intense and immersive experience. I definitely got carried away. I lost about 35 pounds. I really was incredibly skinny and also quite unwell while we were filming. It wasn't very healthy. I don't recommend it. But then also doing the torture scenes, the water boarding stuff, there wasn't really any other way just to do it really.
