The film stars Dane DeHaan and Cara Delevingne as Valerian and Laureline, agents for the government of the human territories who are responsible for maintaining order in the universe. The trailer doesn't go into too many details, but it shows Valerian traversing Alpha, which houses various alien species, as well as space-tripping to different worlds as part of his quest to stop intergalactic termination by a mysterious force. Besson (The Fifth Element, Lucy) was a fan of the comics by Pierre Christin and Jean-Claude Mézières and he was inspired by James Cameron's Avatar to bring this passion project to life.

Valerian (Dane DeHaan) and Laureline (Cara Delevingne) are special operatives for the government of the human territories charged with maintaining order throughout the universe. Valerian has more in mind than a professional relationship with his partner -- blatantly chasing after her with propositions of romance. But his extensive history with women, and her traditional values, drive Laureline to continuously rebuff him.

Under directive from their Commander (Clive Owen), Valerian and Laureline embark on a mission to the breathtaking intergalactic city of Alpha, an ever-expanding metropolis comprised of thousands of different species from all four corners of the universe. Alpha's seventeen million inhabitants have converged over time- uniting their talents, technology and resources for the betterment of all. Unfortunately, not everyone on Alpha shares in these same objectives; in fact, unseen forces are at work, placing our race in great danger.

Opening July 21, Valerian and the City of a Thousand Planets also stars Clive Owen, Rihanna, Ethan Hawke, John Goodman, Herbie Hancock and Kris Wu.
