Found this out too:
Padme’s Handmaidens continue to take Hollywood by storm. First Keira Knightley (Sabé in Episode I) made it big in Pirates Of The Caribbean with LOTR star Orlando Bloom. Then Sofia Coppola (Saché from Episode I) won the Best Screenplay Academy Award for Lost In Translation. Now Rose Byrne (Dormé in Episode II) stars in Troy as Briseis. Not only does she play Orlando Bloom’s cousin in the movie, she’s the love interest of Achilles, played by Brad Pitt. Byrne’s character is Trojan royalty in the film and she is also a priestess of Apollo. When captured by Pitt’s character, he soon falls in love with her. Briseis ends up giving voice to Achilles’ conscience and is one of the few things standing between him and Troy. Can she convince him to end his attack on her city?
But Byrne isn’t the only Star Wars veteran appearing in Troy. Julian Glover plays King Triopas in the film. You may know Glover better as General Veers in The Empire Strikes Back or Walter Donovan in Indiana Jones and the Last Crusade. Glover is one of the first characters to appear in Troy. He ends up being one of the last Greek kings to surrender to King Agamemnon played by Brian Cox.
