It was directed by Wolfgang Petersen and written by David Benioff. It received an Oscar nomination for its costume design.King Agamemnon (Brian Cox) of Mycenae is in Thessaly, Greece, with his army looking to expand territory and influence. On the battlefield, Agamemnon's soldiers prepare to engage in combat against the army under the Thessalonian king, Triopas (Julian Glover). Rather than suffer great losses, Triopas agrees to Agamemnon's proposal to settle the matter in the traditional way - through a decisive match between the best warriors of the opposing armies. Achilles (Brad Pitt) is summoned by Agamemnon, and after arriving, easily kills the Thessalonian champion Boagrius (Nathan Jones). Accepting defeat, Triopas presents Achilles with a scepter as a token for his king. But Achilles refuses, saying Agamemnon is not his king.
