Sometimes I see people finish a film and they go, "Yeah, that was good. Where are we going to eat?"

I wrote the entire history of Alpha because the space station was around for 500 years. I have 30 pages on the history of Alpha. Every ten years what happens. They took control and what happened. Every 80 years, they have to change the communication system because it doesn't work anymore. Some aliens come with new technology, and suddenly you can change the electric system. We wrote the entire story [for Valerian]

Cara [Delevingne] I wanted to be sure that she would be involved. 'Cause she didn't do a lot of films before I met her, so I didn't know if she was serious and so I push her a bit.

Loving a film is like falling in love with a woman or with a man like you never expect it. It it's not the one you think you will be in love with, you know. You think always that he will be with a beard, and black, and big and finally he's Chinese and you know it's the same thing. There's something very organic about the film and if you forgot it, if you don't have this seed in it...this organic flavor in it the film doesn't work it's wrong.

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 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.

Cinema never saved anyone's life, it is not a medicine that will save anyone's life. It is only an aspirin.
