Luc Besson’s sci-fi epic Valerian and the City of a Thousand Planets dropped a teaser video featuring pop star Rihanna, along with the news that the teaser trailer will arrive Thursday.

The news was delivered via EW, which showed off the video of a dancing Rihanna entertaining Valerian. Rihanna’s character’s identity has been kept under wraps (see “Rihanna Cast in Intergalactic Space Opera”), but EW said she plays a “flamboyant supporting role” and will have “several personas.” She will be seen in 20-plus minutes of the movie, according to Besson.

The film, which is based on the French bande dessine written by Pierre Christain and illustrated by Jean-Claude Mezieres, debuted its first poster at New York Comic Con (see “First 'Valerian and the City of a Thousand Planets' Poster”).

The film opens in theaters on July 21, 2017.
