Fifth Element writer-director Luc Besson used his first official tweet to announce his next sci-fi project, Valerian and the City of a Thousand Planets, based on the popular French graphic-novel series. Besson gave fans a sneak peek of the latest Valerian artwork and announced the films’ starring duo: Cara Delevingne (Paper Towns) and Dane DeHaan (The Amazing Spider-Man 2).

Delevingne and DeHaan will play a pair of time-traveling agents, Valerian and Laureline. The first story in the popular French series by Pierre Christin and Jean-Claude Mézières was published in 1967.

Both actors will also be appearing together in the upcoming Tulip Fever alongside Ex Machina‘s Alicia Vikander, Christoph Waltz, and Jack O’Connell. Delevingne will make her highly anticipated YA adaptation debut this summer in Paper Towns. Fans also recently got a sneak peek of the model-actress’ makeover for Suicide Squad, which hits theaters in 2016.

Besson is set to write, direct and produce the film, calling it his “biggest challenge” in a post on his Facebook page, saying “I have around 800 days of work ahead of me, plenty of time to be discouraged or feel lonely, so I’m counting on your support. I will try to share my adventure with you as much as I can.”

Valerian will premiere sometime in 2017.
