It's fear that makes us lose our conscience. It's also what transforms us into cowards.

The world is not about Batman and Robin fighting the Joker; things are more complicated than that. And nothing is scarier than the people who try to find easy answers to complicated questions.

I loved Chiara Mastroianni voice, her talent, her generosity. We rehearsed for two months...She's a workaholic and perfectionist, like Vincent [Paronnaud] and myself.

When you make a book or you make a movie, it is almost like hitting on somebody. It's not because you want to seduce people that you will seduce them; you can hit on somebody and it doesn't work. But when you hit on them and it works, then it's really cool.

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.

Life is complex. You don't have any person who is nice from the beginning until the end. You don't always have the notion of redemption. The bad people don't always pay.

I think animation is like running a marathon, and making a movie is like a 100 meter sprint. The question is: are you a marathon man or are you a sprinter? I realized that I was more of a sprinter than a marathon man. With a long, long project, I get bored easily.
