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.

In the past, if I didn't work, I didn't eat but now I feel I can not work and I won't starve.

Because I had children relatively late - in my 40s rather than in my 20s - it wasn't anything I ever knew that I would do. It kind of happened to me: I met the right woman and we had children. It was a revelation because it suddenly makes me realize "Oh, I get it. Now I know what to do with the rest of my life."

I had this extraordinarily bizarre moment when, two Fridays ago, my missus gave birth to our second child at 11am and by the same time the following day I was sitting around a table with Ridley Scott, Russell Crowe and Leonardo DiCaprio in Rabat in Morocco, rehearsing a scene we were going to shoot the next day.

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 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.

The Secret Service I'm really excited about because Matthew Vaughn directed it. I've done a couple of movies with him - Stardust, which is one of my favorite films, and Kick-Ass, which is just a crazy, wonderful movie.
