300

300 is a 2006 epic historical action film directed by Zack Snyder, who co-wrote the screenplay with Kurt Johnstad and Michael B. Gordon. It is based on the 1998 Dark Horse Comics 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 (Gerard Butler), who leads 300 Spartans into battle against the Persian "God-King" Xerxes (Rodrigo Santoro) and his invading army of more than 300,000 soldiers. As the battle rages, Queen Gorgo (Lena Headey) attempts to rally support in Sparta for her husband. The film also features Michael Fassbender in his film debut.

The story is framed by a voice-over narrative by the Spartan soldier Dilios (David Wenham). As an unreliable narrator, Dillos introduces various historical inaccuracies and other fantastical elements, placing 300 within the genre of historical fantasy. 300 was filmed mostly with a superimposition chroma key technique to replicate the imagery of the original comics.
