I'm not a writer, inherently. Most of the writers I've met have stories they need to tell. I don't have that. I'm an interpreter. I like getting a script, seeing a character and thinking, "Oh, wow, I know what I can do with that."

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.

The Peugeot is a very unthreatening car.

I have an enormous amount of respect for Nicole Kidman. She's just done so many great movies and she's been out there at the forefront of carrying films and being a movie star. On set, it really pays dividends because when you're performing with her, she knows exactly how to play it. You don't have to compensate for her in any way.

When you're making a psychological thriller, what you need to do is have an audience on shifting sand so they're never quite sure where they are.

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 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.
