You're in a very nice position as an actor when you're portraying a piece of history that actually happened and portraying characters that actually existed. There's so much more to draw on and your research as an actor becomes much easier than if it's some fiction that you're trying to create a world around and background and history.

There's very exciting directors who haven't made a feature yet. That's what's cool about the job - the ever-changing landscape of people you could potentially work with.

Because I used to play a lot of sport, I've always been in decent enough shape. When I used to get asked to do a bit of body work before a photo shoot I'd lie and say, 'Yeah, I'm going to the gym.' I literally never did anything.

I think you've really got to cling to what makes sense to you. Obviously, I'm not a serial murderer in my real life, so that's where you have to delve into and do all the research. But, you have to find something likable in the character.

I think you only watch stuff you've done once because I don't think it's that beneficial to you. I think it's important to sometimes be like, 'What's that thing I'm doing with my face? I didn't think I was doing that.'

I'm probably the worst person for 'Men's Health' to interview.

I guess I'm just lucky with my genes.
