I've always been into dark colours.

My first time acting for camera really was for Steven Spielberg in War Horse. I was trained in theater and I was actually working in theater at the time. I had a small role with the Royal Shakespeare Company, which is a huge prestigious theater company back in England. I honestly thought that was as good as it got.

It's weird when people are just staring at you because the thing is, people are not quite sure ... I get a lot of: "Are you off the TV?" It's funny. I don't and I don't get to the sort of clubs where people expect to see you.

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 most actors will tell you the same thing; when you're not working you put 100 percent into every audition.

Every time I get a role I think, 'I've actually fooled them again, I can't believe they keep falling for this!

'Great Expectations' is one of the greatest stories.
