Valerian and the City of a Thousand Planets (French: Valérian et la Cité des mille planètes) is a 2017 French science fiction action-adventure film written and directed by Luc Besson and co-produced by Besson and his wife, Virginie Besson-Silla. The film is based on the French science fiction comics series Valérian and Laureline, written by Pierre Christin and illustrated by Jean-Claude Mézières. It stars Dane DeHaan as Valerian and Cara Delevingne as Laureline, with Clive Owen, Rihanna, Ethan Hawke, Herbie Hancock, Kris Wu, and Rutger Hauer in supporting roles. Besson independently crowd-sourced and personally funded Valerian and, with a production budget between $177–209 million, it is both the most expensive European and independent film ever made. It has already been considered a box office bomb.
The film was released by STX Entertainment on 21 July 2017 in the United States and on 26 July in France by EuropaCorp. Valerian received mixed reviews from critics, who criticized the writing and plot but praised the visuals, and has grossed $27 million worldwide. In its opening weekend, after a very low opening and taking into account its budget, the film has already been considered a box office bomb. In France, the film had the second best opening day of 2017 and was projected to gather 1.8 million spectators during the first week.
