Warner Bros. and Legendary Pictures have released the first trailer for Noam Murro’s 300: Rise of an Empire, a companion film to the Zack Snyder-directed blockbuster 300. The film is produced by Snyder, who adapts the Frank Miller graphic novel with screenwriter Kurt Johnstad (300, Act of Valor).

Rise of an Empire follows Athenian general Themistokles (Sullivan Stapleton) as he battles Persian king Xerxes (Rodrigo Santoro) and his vengeful navy commander Artemesia (Eva Green). The events occur at the same time that King Leonidas is leading his 300 Spartans into the Battle of Thermopylae.

This looks awesome:
