I wanted to do something that was entertaining - but with a catch.

That's the storyboard that we have in the beginning [of Valerian]. It's an easy shot. It's just a spaceship coming in. That's the first layout. On the first layout, we see the timing of the shot and the speed. It starts to get some shadows, and we see that everything is moving in the back.

I wanted to prove that I could do something, so I made a short film. That was in fact my main concern, to be able to show that I could do one.

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... Money should be like third or fourth or fifth, I'm not saying lets get rid of money, but how can we put money as number one? As the only value, like if you are rich, you're famous you go VIP, why? It's just insane, the way we've transformed the society.

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.

If you're someone from the government and you meet people from other countries, you want to know who you're dealing with. It's the same for them [in Valerian].

That's a KORTAN DAHUK. That's the first alien we see in the film [Valerian]. That's another artist. The first one was Chinese, the one with the space station. This one is American. Personally, that's my favorite alien. I love him. I love his profile and his face. There is such a sweetness and almost a sadness in his face.
