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.

I think in this world and this industry, if you let it, it does. And I feel that the people who don't have good friends and family around them are the ones who get a little funny. But I'm very lucky. I have good friends and good family and if I ever stepped out of line, my mom would take me down!

I've been very reluctant on the Twitter front. But I do Instagram now, so I'm slowly coming around. I'm quite a private person, so much of what I do for my job means that I have to be quite public so I'm just nervous about everything being public. I might turn around. Three years ago, I was against all social media but I actually really enjoy Instagram now. Who knows? I never say never!

I like being outdoors a lot, and I come from a small village that's fairly remote.

There's nothing nicer than coming back to your village, where people like my mum's friends take the mick out of me. I prefer that to the craziness of Hollywood.

I wouldn't want to see any animal in pain, no matter what.

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