Plot: Based on Frank Miller's graphic novel interpretation of the real life Battle of Thermopylae, and a more extensive use of the fully CG environment techniques developed in such recent films as "Sky Captain" and "Sin City". In the year 480 BC, emperor Xerxes of Persia attempted to invade Greece and add it to his growing empire. At the time, Greece was made up of city-states, the greatest of which were Athens and Sparta. Facing invasion from the Persians, the Greek city-states attempt to raise an army to fight for their homes. However raising this army will take time. In order to buy the time it takes to get an army ready, King Leonidas of Sparta volunteers himself and 300 of his elite guard to hold off the entire Persian army of 100,000 plus men. They made their stand at Thermopylae knowing they would die.
