I actually collect old First and Second World War memorabilia.

If a horse doesn't want to do something, you're not going to make him do it. They're incredibly powerful animals.

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'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!

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.

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.

I'm not scared of animals, except for rats. I'll break down in tears if I see a rat!
