Troy is a 2004 epic historical action film directed by Wolfgang Petersen and written by David Benioff. Produced by units in Malta, Mexico and Britain's Shepperton Studios, the film features an ensemble cast led by Brad Pitt, Eric Bana, Peter O'Toole, Julie Christie, Sean Bean, Diane Kruger, Brian Cox, Brendan Gleeson, Rose Byrne, Saffron Burrows and Orlando Bloom. 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 historical 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.
