• Zack Snyder's new Netflix movie, "Rebel Moon - Part One: A Child of Fire" is a science-fiction epic.
• It follows a former soldier as she tries to rally a band of fighters to defend a helpless planet.

Science-fiction fans can finally watch Zack Snyder's "Rebel Moon" now that it has arrived on Netflix, just in time for the holidays.

The director told Empire Magazine that the film started out life as a potential "Star Wars" movie shortly after Disney bought Lucasfilm for $4 billion. But it didn't work out, and Snyder kept the idea of "Rebel Moon's" expansive universe for himself.

The ambitious adventure takes place in a universe ruled by a tyrannical group called the Imperium, led by Regent Balisarius (Fra Fee).

When the Imperium threatens the home of former soldier Kora (Sofia Boutella), she searches the galaxy for other fighters who will help her stand against the threat.

Here's a look at the "Rebel Moon" cast and who they play.
