Luc Besson continues to tease the upcoming Valerian and the City of a Thousand Planets on Facebook, where the director recently posted a photo of stars Cara Delevingne and Dane DeHaan in a spaceship called the Intruder.

Delevingne and DeHaan star as a pair of time-traveling agents in the sci-fi film, based on a French graphic novel series. Rihanna, Ethan Hawke, Herbie Hancock, John Goodman, Clive Owen, and Rutger Hauer also star.

Besson, whose previous credits include 2014’s Lucy and 1997’s The Fifth Element, has called this film “the biggest challenge” of his career. “I have around 800 days of work ahead of me, plenty of time to be discouraged or feel lonely,” he wrote on Facebook, “so I’m counting on your support.”
