'Valerian 2' will be "less expensive" than the first movie.
Director Luc Besson has revealed the follow-up film to 'Valerian And The City Of A Thousand Planets' would not cost as much to make as the first motion picture in the franchise because the story is "different", but a third project would see the price shoot back up.
He said: "The price depends on the story. The story of the second one is less expensive. The third one is almost the same than the first. But it depends on the story, the price doesn't go up because you want to. It depends of what you're saying. But the second one is less expensive.
"It's pretty less, the story's different so ... and there's some elements that you can use that we have in the first one and then we have the knowledge now."
While scripts for a second and third 'Valerian' are thought to have been written, it's not 100 per cent confirmed a sequel will be made, but Besson admitted he is hoping there is a positive reaction from the DVD/Blu-ray release because he is keen to work on a follow up.
He added to Collider: "So let's see how it's working, let's see how the thing ... but if it goes normally then, yeah, I want to do the number two for sure."
In August, Besson admitted he would love to make a sequel to the first film with Cara Delevingne and Dan DeHaan reprising their roles.
Asked if he'd make another 'Valerian' film, he said: "Yeah, I will sign tomorrow. I would love to. We had so much fun with Cara and Dane. I think the three of us will sign tomorrow if we can do another one or two.
"Because they're cops, every film is an adventure. There's a problem, there's a killer, there's something we have to discover the truth and you can do 20 films like this, it's like 'Starsky and Hutch' in space.
"Every episode is a new trial. And you're not linked by the first one, the link is just the two characters, so it could be totally different. It's more difficult when you have something like 'Spider-Man' or 'Transformers', as it's always the same kind of thing, and you can't explode the thing. Here you can. You can do something totally different, which I like."
