It is loosely based on Homer's Iliad in its narration of the entire story of the decade-long Trojan War—condensed into little more than a couple of weeks, rather than just the quarrel between Achilles and Agamemnon in the ninth year. Achilles leads his Myrmidons along with the rest of the Greek army invading the historic city of Troy, defended by Hector's Trojan army. The end of the film is not taken from the Iliad, but rather from Quintus Smyrnaeus's Posthomerica, as the Iliad concludes with Hector's death and funeral.
