The darker the film, the more vital everyone's sense of humor is on set.

I think you need to be able to see a lot of negative in things in order to extract material, so there's probably something to that. A lot of the people I used to work with were very, very, very unfunny offstage, so that's a pretty common thing.

We shot that in Morocco, and got out of the country at the beginning of July - and two months later came the attack on Twin Towers. The movie was then released in December, so that kind of atmosphere is not something that was unfamiliar to me.

I do believe in reading signs if they're really obvious to you. Things happen. Someone will say something to you today in the morning and then later on that day someone will mention the same thing and then the next day someone will mention it again. There's a reason why three people have said something within twenty four hours.

I enjoy just being cocooned in production and it's completely different to your other life that you have. I enjoy that. I enjoy being on the set and hanging out and talking to whoever we're working with and just being in the moment.

If you're lucky enough to be involved in a film that's about something very real and that you hope will continue to hold up in 20 years' time it just gives you more energy and makes it feel all the more worthwhile.

I'm spending all my time and energy on the project at hand.
