Based on Frank Miller's latest graphic novel Xerxes and told in the breathtaking visual style of the blockbuster 300, this new chapter of the epic saga takes the action to a fresh battlefield—on the sea—as Greek general Themistokles (Sullivan Stapleton) attempts to unite all of Greece by leading the charge that will change the course of the war.

300: Rise of an Empire pits Themistokles against the massive invading Persian forces led by mortal-turned-god Xerxes (Rodrigo Santoro), and Artemesia (Eva Green), vengeful commander of the Persian navy.
