I did The Fifth Element and [Jean-Claude] Mezieres, the artist of Valerian; he was working on Fifth Element. And he's actually the one who say, why don't you do Valerian?

For example, in your house, you have the heater on the ground itself. Here, it's the gravity. No matter where you are, that's where the gravity is coming from. It's almost like a carpet that you put down. If you're on the other side, it doesn't matter to us because we're still walking on the ground. Actually, at the beginning of the film [Valerian], we see when they install the gravity system.

You know, money will never save anyone. Compassion can save someone, love can save someone, money will never save anyone. And as long as the entire society will put money first...

It's just insane, the way we've transformed the society.
