The first official trailer for Zack Snyder’s Rebel Moon is here, revealing the sci-fi epic he’s been dreaming about for years. The trailer abounds in action, with the thrust of the story—a peaceful galaxy is set upon by the armies of a tyrannical lunatic and must count upon one woman to help lead them to victory against this madman—is mostly left to the visuals to do the explaining. Helpfully, we also have narration from none other than Anthony Hopkins (he plays a man named Jimmy in Snyder’s film), who relates a myth about a young girl who was supposed to bring peace to the galaxy. It’s a peace that, as of yet, seems incredibly elusive. He’s never seen it, or the girl, in his long life.

That young girl, it seems, turns out to be Sofia Boutella’s Kora, a mysterious figure living among the peaceful villages who must recruit enough fighters to make a stand. Kora’s rag-tag army will include outsiders, peasants, insurgents, and orphans of war from various worlds, all brought together under the banner of resisting tyranny and avenging the wrongs of men like Admiral Noble (Ed Skrein), the pitiless tyrant who claims all that he sees as his own.

Rebel Moon will arrive in two parts. Part 1: A Child of Fire arrives first, on December 22, while Part 2: The Scargiver lands on April 19, 2024. It’s a film that Znyder’s been dreaming about for years (it began as a potential Star Wars spinoff more than a decade ago) and is based on a script he wrote with his Army of the Dead co-writer Shay Hatten and his 300 co-writer Kurt Johnstad.

Joining Boutella and Hopkins are Djimon Hounso, Carey Elwes, Charlie Hunnam, Corey Stoll, Michiel Huisman, Alfonso Herrera, Doona Bae, Ray Fisher, Rupert Friend, and Stuart Martin.

Check out the teaser trailer below. Rebel Moon arrives on Netflix on December 22:

Here’s the official synopsis for Rebel Moon:

From Zack Snyder, the filmmaker behind 300, Man of Steel, and Army of the Dead, comes REBEL MOON, an epic science-fantasy event decades in the making. When a peaceful colony on the edge of a galaxy finds itself threatened by the armies of a tyrannical ruling force, Kora (Sofia Boutella), a mysterious stranger living among the villagers, becomes their best hope for survival. Tasked with finding trained fighters who will unite with her in making an impossible stand against the Mother World, Kora assembles a small band of warriors — outsiders, insurgents, peasants and orphans of war from different worlds who share a common need for redemption and revenge. As the shadow of an entire Realm bears down on the unlikeliest of moons, a battle over the fate of a galaxy is waged, and in the process, a new army of heroes is formed.
