300 is a 2007 American epic historical war film directed by Zack Snyder, who co-wrote the screenplay with Kurt Johnstad and Michael B. Gordon, based on the 1998 comic book limited series of the same name by Frank Miller and Lynn Varley. The film, like its source material, is a fictionalized retelling of the Battle of Thermopylae in the Greco-Persian Wars. The plot revolves around King Leonidas, who leads 300 Spartans into battle against the Persian "God-King" Xerxes and his invading army of more than 300,000 soldiers. As the battle rages, Queen Gorgo attempts to rally support in Sparta for her husband. The film also features Michael Fassbender in his film debut.
