Warner Bros. announced today that the 300 prequel 300: Battle of Artemisia has been re-titled 300: Rise of an Empire.

Sullivan Stapleton (Animal Kingdom, Strike Back) stars as Themistocles, who leads a group of Spartan warriors to take on the mighty Xerxes (Rodrigo Santoro). Eva Green plays Artemisia, the goddess who persuades Xerxes to do battle with these Greek soldiers. Jamie Blackley also stars.

Noam Murro is directing from a script by 300 writers Kurt Johnstad and Zack Snyder, with production already under way.

This is not the first time this project has underwent a title change. First known as Xerxes, we reported last June that the title was changed to 300: Battle of Artemisia. We'll have to wait and see how long this current title will stick around for.
