HollywoodReporter.com — Charlie Hunnam, Djimon Hounsou, Bae Doona and Ray Fisher have boarded the starship to Rebel Moon, the epic sci-fi fantasy feature that Zack Snyder is directing for Netflix.

Jena Malone, Staz Nair, E. Duffy, Charlotte Maggi and Sky Yang have also signed on for parts in the feature, which is slated to begin shooting in April.

Sofia Boutella is leading the ensemble in the story of a peaceful colony on the edge of the galaxy that is threatened by the armies of a tyrannical regent named Belisarius. Desperate, the colonists dispatch a young woman with a mysterious past to seek out warriors from neighboring planets to help them make a stand.

Character details are about as easy to find as an honest galactic mercenary, but sources say Hounsou is playing a character named General Titus (good/bad guy status unknown), Bae is a nemesis who is proficient with a sword, while Fisher is a resistance fighter named Blood Axe.

Snyder co-wrote the script with Army of the Dead co-screenwriter Shay Hatten and Kurt Johnstad, who co-wrote 300, Snyder’s adaptation of the Frank Miller comic. Snyder and Johnstad are receiving story-by credit.
