I'm very interested in talking about children in this moment where you are going to become a teenager, and I think it's very relevant to use a fairy tale to talk about that.

Maybe our Earth is totally alone in the universe.

I try to simplify things for the children.

What is very exciting with children is they like to play, and they don't care so much about the meanings [of things], and they are just excited to have weird scenes to do or weird things to do, like playing deaf, or playing sick, or swimming in the water.

I don't have storyboards, but I have some very strict rules, like not moving the camera.

I used to live in a little city by the sea, and the feeling of isolation - it was not like living in Paris or London. It was a bit apart from the main city, and [it gave me] this feeling of isolation and also being close to nature, with nature as a surrounding and also a frontier, from the society of the world.

With digital, you can shoot longer, take more risks.
