I played old men back in drama school. It's just now that I'm drawing level with the age of the characters I play, but I'm fine with that, and I've certainly never envied people who became hugely famous when they were young.

I was the youngest child and got a lot more freedom than my brother and sister. I used to wander, doing my own thing under the radar, but I didn't get in bad, bad trouble.

With 'Duplicity', I was a little bit like, 'This isn't that hard of a movie.' This isn't like some huge brain trust of a movie. You gotta be a little bit awake to follow the plot, but it's really just a kind of light entertainment. It's like those Cary Grant movies, which are not meant to be anything other than diverting. In a nice way.

I consider myself an atheist. My wife is Jewish. And I'm fine with my son being raised as a Jew. He's learning Hebrew and is really into it. I will talk to my own son about my atheism when the time is right. But there's a great tradition of Jewish atheism, there are no better atheists in the world than the Jews.

As an actor, to have achieved financial stability is amazing. But I always have this weird fear that I'm not going to get any more work; it's about not having enough money.
