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.

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!

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've always been into dark colours.

I think I got into acting because I kind of had not much else to do! I guess I was kind of looking for something challenging. I heard about the London Theater scene and it was very different from the upbringing that I had and it felt like a challenge. And the whole sort of London Theater schools, I was told that 6,000 apply and there are like 30 accepted to each one. I was like, "Yeah. Let's see if we can do that!"

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!

Ralph Fiennes was a big hero of mine acting-wise growing up and while I was training. I just find him so watchable. He was playing this very intimidating character when we worked together and it certainly felt like he was in character off set as well! He was very cool. Before a scene, he'd be like, "Come on. Let's improvise. Let's just do stuff." But Jesus Christ. He's Ralph Fiennes!
