Sin City author Frank Miller's sweeping take on the historic Battle of Thermopylae comes to the screen courtesy of Dawn of the Dead director Zack Snyder. Gerard Butler stars as Spartan King Leonidas and Lena Headey plays Queen Gorgo. The massive army of the Persian Empire is sweeping across the globe, crushing every force that dares stand in its path. When a Persian envoy arrives in Sparta offering King Leonidas power over all of Greece if he will only bow to the will of the all powerful Xerxes (Rodrigo Santoro), the strong-willed leader assembles a small army comprised of his empire's best fighters and marches off to battle. Though they have virtually no hope of defeating Xerxes' intimidating battalion, Leonidas' men soldier on, intent on letting it be known they will bow to no man but their king.
