I don't want to show kids that I am smoking.

I'm always attracted by people who are lost in their time. I think it helps us.

I think we have the wrong notion of commercial and intellectual or artistic film. Because all films are commercial.

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.

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? And I said because we can't make it. And you really have to wait for Avatar and to suddenly think oh okay, maybe we can think of it. But before Avatar, just forget it.

I'm a big Star Wars fan.

If we wanted to make it the way I imagined I knew that we would have to wake up earlier and start very early. So we prep like crazy. And the competition you have is like Avatar, you have Star Wars, you have all the big Marvel stuff. So if you want to come in the race, you know, don't be pretentious.
