"Valerian and the City of a Thousand Planets" flopped due to a combination of factors. Despite its impressive visual effects and ambitious world-building, the film struggled with a convoluted plot and underdeveloped characters, which made it hard for audiences to connect. Additionally, the marketing failed to clearly communicate its appeal, and competition from other blockbuster films at the time diluted its audience. Lastly, the film's high production costs resulted in a significant financial loss, despite its international appeal.

Director Luc Besson has expressed interest in continuing the story, but there has been no confirmation of production or release dates for a sequel. Keep an eye on official sources for any future updates.
