Star Wars: Rogue One has assembled quite the fleet of galactic warriors.

According to Entertainment Weekly, director Gareth Edwards introduced the full cast of the standalone film at Disney's D23 fan expo in a video from set, where they had just filmed the first scene.

In addition to Felicity Jones, whose casting was previously announced, the Rogue One cast will also include Diego Luna, Ben Mendelsohn, Forest Whitaker, Mads Mikkelsen, Donnie Yen, Jiang Wen, Riz Ahmed and Alan Tudyk, who will play a motion-capture character.

Rogue One will set up the events of the original Star Wars, detailing the stories of the people who stole the Empire's schematics for the Death Star, those who helped Luke destroy the battle station and the cost they paid for their roles in the war. And unlike most Star Wars films, Rogue One will dig into the nitty-gritty of a ground war, not a space war.

"Rogue One takes place before the events of Star Wars: A New Hope and will be a departure from the saga films but have elements that are familiar to the Star Wars universe," Lucasfilm president Kathleen Kennedy said in a statement. "It goes into new territory, exploring the galactic struggle from a ground-war perspective while maintaining that essential Star Wars feel that fans have come to know. Gareth is such an innovative director and I'm so excited to be working with him and the extraordinary ensemble cast he's selected for Rogue One."

Star Wars: Rogue One will hit theaters on Dec. 16, 2016.
