The first teaser trailer for Luc Besson’s sci-fi epic Valerian and the City of a Thousand Planets has arrived.

Besson promised the trailer yesterday when he shared a clip of Rihanna yesterday (see “'Valerian and the City of a Thousand Planets' Teaser Stars Rihanna”). The trailer is an eye-popping array of aliens, futuristic cityscapes and changing scenery.

The official synopsis reads:

Valerian (Dane DeHaan) and Laureline (Cara Delevingne) are special operatives for the government of the human territories charged with maintaining order throughout the universe.

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.

The film opens in theaters on July 21, 2017.
