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.

Interestingly, this character [Doctor Nash] is probably closer to me than somebody like the evil Sir Godfrey in Robin Hood or Lord Blackwood who wants to take over the world in Sherlock Holmes. This is a character that's English, he's based in London, and so it's closer to me than a lot of stuff I've been doing recently.

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.

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.

Part of me was fascinated by the idea that I would only get next week's episode a week in advance and wouldn't actually know where I was going with it, until the script landed on my mat. But, part of me wanted to know what was going to happen.

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.

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.
