The fact of having this very new context, this unheard-of way of working, for me was very pleasant. I didn't feel that I was working, that I had any kind of burden to wear, to carry. I really was very happy and very lighthearted during the whole process of making the film [Certified Copy], of shooting it.

It is a very important film, Life And Nothing More, in that what was filmed was inspired by a journey I had made just three days after an earthquake. And I speak not only of the film itself but also of the experience of being in that place, where only three days before 50,000 people had died.

I think I'm no different to my friends who are doctors or businessmen or architects - we all started watching films of the golden age together. But whether I'm making films or writing poetry or doing photography, it's very much rooted in my sense of unease. And that's really where everything goes back to.

I think, just as footballers play better at home, maybe film-makers, too, create better at home, even though the rules of football are the same wherever you go.

I think the contrast between these two in the professional world of cinema mattered to me. One who has reached the ultimate point of being a star, who knows how to do everything very well, facing another person who would throughout the making of the film transfer his anxiety to both of us, to me and to Juliette, as to whether or not he would be capable of fulfilling his role. This in itself created a challenge that was actually very good for me, since I hadn't ever counterposed two such performers before, creating that challenge between someone who knows their part and someone who doesn't.

Film is very much a universal and common voice, and we can't limit it to one particular culture.

Having an international voice is not really about whether we speak Persian or any other language.
