With a horror movie most of the actual jumps and scares are made in the edit. It's often not very scary on set and then you watch the film and suddenly it's very scary because the way the jump scares fit together building up the suspense in the audience because it's making them jump when they're least expecting it.

The work my mum does, a lot of it is re-housing homeless people, that's a real job. I play make-believe and dressing up for a living!

It was a movie [The Railway Man] that stayed with me a long time. It's still one of the things I'm most proud of. I got to know the man that I was playing and unfortunately he passed away just before the movie came out. It's one that meant a huge amount to me, and one that I'm particularly proud of.

When I was growing up, there was a man who gave me lessons and things. I'm very dyslexic so he used to give me extra reading and writing. And he always knew that I was interested in stuff but he never told me that he was in the Second World War himself. One day he gave me his helmet that he had worn through the North Africa Campaign. It was just before he died. So I've got his helmet. That was pretty special to me.

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!

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

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.
