I'm sure part of the baggage that I bring having played a lot of villains is also pertinent to the movie [ Before I Go To Sleep], because I'm sure people look at me and think, "Oh, I'm not sure I trust him or not."

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.

Rowan Joffe was on top of everything. He knew exactly how he wanted everything to be, right down to the fact when I made those telephone calls, I didn't do it afterwards in a studio. I think that's how he operates. He likes it to be as real and as clear as possible.

And I think in your 40s, you land a little bit, physically and mentally, you arrive at a place where you feel you've learned some stuff. Having children at that point meant I had something very useful to do for the next 20 years.

I'm very organized and tidy in my home life and I generally do something myself rather than farm it out to somebody else. I don't have an assistant or anything because I think I can do it myself.
