I wrote the plot [for the Persepolis ]and Vincent [Paronnaud] and I wrote and discussed the shooting of the script. Vincent then took care of the production design, the actual shooting, and what was going on within each scene. It's very difficult, though, to draw a line between who did what. Because Vincent would say something, and I would add something, and at the end you have this film, yet no clear idea of who did what.

I don't watch many comic-book movies. But I loved 'Sin City.'

It is dangerous when you start calling people from one part of the world terrorists or fanatic, and you reduce them to some abstract notion. If evil has a geographical place, and if the evil has a name, that is the beginning of fascism. Real life is not this way. You have fanatics and narrow-minded people everywhere.

I chose the actors that I was in love with. I cannot work with people that I don't personally like a lot. They can be the best actor in the world, but if the first contact is not good, if I don't fall in love with them, then I don't want to work with them. It's impossible.

I think the best work of the director is to listen to what all the technicians around him have to say, but then the thing is to take the best decision, what you think is the best. Then, that is the moment where you have to have all the film in your head and imagine how all of that will fit together.

The most exciting time is when I think of an idea and how I imagine I can make it. It would be wonderful if there was a projector inside my eye that and it could just put the idea on the screen for people to see.

I wanted to make a real love story with a bad ending, because a love story that ends good is the life of everyone - you and I, for example. I always say to people, You know, if Romeo and Juliet got married, nobody would care about them. Imagine Romeo and Juliet, six kids yelling, mama, mama, papa, papa.
