I think that among my friends I'm known as being a hard worker; I think if you want to be an actor, there can't be any compromise. You have to work all day, every day. It's not a 9-5 job. There's always something to learn.

Determination becomes obsession and then it becomes all that matters.

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.

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 had a great drama teacher, and he sort of made out drama school as this incredibly difficult thing to get into: 6,000 people apply every year, and some of the schools only have 12 places. It's a phenomenally difficult thing to get into. And that excited me - I wanted that challenge.

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!
