The film opens with a Combat by Champion between Boagrius and Achilles...except Achilles didn't bother to show up.
Triopas: Boagrius has that effect on many heroes.
Helen and Paris at the start.
Helen: You shouldn't be here. Paris: That's what you said last night. Helen: Last night was a mistake. Paris: And the night before that? Helen: I have made many mistakes this week.
Near the beginning of the movie, the look on Hector's face when he realizes just where Paris is... it's somewhere between Oh, Crap! and You Have GOT to Be Kidding Me!.
This exchange right before Paris reveals he secretly brought Helen with them to Troy. Hector's expressions (especially the massiveOh, Crap! face when he finds out) are just glorious.
Paris: Do you love me, brother? Will you protect me from any enemy? (Beat) Hector: ...The last time you spoke to me like this, you were ten years old and you had just stolen father's horse. What have you done now?
In the Director's Cut, two of Agamemnon's messengers are dispatched to find Odysseus and come across a lone shepherd resting in the hills. When he hears who they're looking for, the shepherd begins to angrily rant about how Odysseus sucks, offending the men with his lack of respect for his king. The shepherd is Odysseus and he has a good laugh at their expense.
Ajax being so eager to join in with Achilles and the Myrmidons in their assault on the beach, and him being so pissed off that his vessel isn't going any faster, that he pulls off one of the rowers and starts rowing himself.
Row you lazy whores, row! Greeks are dying!
This exchange outside the newly sacked temple of Apollo:
Odysseus doesn't mince words after Menelaus's death.
Odysseus: The men believe we came here for Menelaus's wife. Won't be needing her anymore.
Agamemnon: My brother's blood still wets the sand and you insult him!
Odysseus: It's no insult to say a dead man is dead.
Nestor says the men's morale is merely "weak".
Odysseus: Weak? They're ready to swim home!
Agamemnon rants about Achilles is as likely "to spear me as to speak to me!"
Achilles attempts an After Action Patch Up to Briseis who, not unreasonably after nearly being gang raped, keeps slapping his hand away as he tries to mop her wounds. He then throws the cloth at her and she throws it back at him!
