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."

You need to try to find a way to humanize your villains. Genuine villains, in real life, still have mothers and daughters and sisters, and they fall in love. They don't walk around with a big sign saying, "Bad guy," on their head. They think they're good guys. If you can play that, I think it makes it more interesting.

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.

I just invited close friends and family, the usual suspects whose opinion I value but who I know will enjoy the film [Before I Go To Sleep]. I don't know how difficult it is for them to suspend their disbelief because they obviously know me and what they're seeing is not me.

You sign for a sequel for everything these days, just in case, options. In the past, you avoided them like the plague because it meant somewhere down the road you couldn't take a job because you had to do a sequel. Now it's a feature of pretty much any feature you do.

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.

All these portrayals we see of knights fighting must be absolute rubbish because knights in armour could literally have only had two or three blows and then they'd have had to sit down to have a cup of tea.
