The kind of sleep that I had during my own film [Certified Copy] screening in Cannes is different. It's not because of the specificity of the film. It was because of my relationship as an author to this film. Usually when I take my films to festivals, I feel incredibly anxious about them. I wonder how it will be received, how the audience will react. I feel deeply responsible for them. Whereas this time, I didn't have that responsibility on my shoulders.

A digital camera does have many advantages and I was a believer that digital video would be a big influence on film-making.

All the different nations in the world, despite their differences of appearance and religion and language and way of life, still have one thing in common, and that is what's inside of all of us. If we X-rayed the insides of different human beings, we wouldn't be able to tell from those X-rays what the person's language or background or race is.

In my experience as a director, I think there is obviously something of the way men - maybe that's a common point with Shirin - the way men see women in the film, and the way these two characters see each other.

My car's my best friend. My office. My home. My location. I have a very intimate sense when I am in a car with someone next to me. We're in the most comfortable seats because we're not facing each other, but sitting side by side. We don't look at each other, but instead do so only when we want to. We're allowed to look around without appearing rude. We have a big screen in front of us and side views. Silence doesn't seem heavy or difficult. Nobody serves anybody. And many other aspects. One most important thing is that it transports us from one place to another.

There were years when Hitchcock was like a master to me, but now I think he's so artificial. I can watch films and say how technically beautiful they are, but I'm not impressed by any technicality.

We are nothing but a link between our culture and what we can actually produce.
