This action adventure is faithfully adapted from the graphic novel 300 by Frank Miller in which Spartan King Leonidas (Gerard Butler) and his 300 Spartans fought to the last man against Persian King Xerxes (Rodrigo Santoro) and his massive army. Facing insurmountable odds, the Spartans` heroism and sacrifice inspires all of Greece to unite against the Persian invaders. The story is loosely based on the Battle of Thermopylae which took place in the summer of 480 BC.
