I got sent the script [ Before I Go To Sleep] as usually happens and you have a little look. I know it's a bit of a cliché, but it was absolutely a page turner. I mean, I wanted to find out what happened next.

I think it serves the purpose of the film if the premise is that you're unsure of me because you've only ever really seen me play villains.

It's great to have the chance to play a character before he goes to the dark side, or the yellow side if you will. Normally, you don't get that opportunity. The narrative of a movie usually demands that you are that guy from the start.

Rowan Joffe is very specific. I mean, he wrote it as well and he has a very orderly writer's mind and the same applies to his directing.

In the film industry you never really know if all the various ingredients will come together - sometimes they do, and sometimes they don't. As an actor, you don't have much control over those things. It's a director's medium in that sense. All you can really do is minimise the risks of being involved in something that might not work and look for something that also suits you.

I loved making The Imitation Game and it's really gratifying to hear the audience's response to the character that I play.

I've played lots of villains in my time and I think the reason they've been so successful is that they're not two-dimensional. They're not black and white. That's the gig.
