Ebert reviews Troy, and reveals he needs to go back to high school:

Chief among their leaders is Achilles, said to be the greatest warrior of all time, but played by Brad Pitt as if he doesn't believe it. If Achilles was anything, he was a man who believed his own press releases. Heroes are not introspective in Greek drama, they do not have second thoughts, and they are not conflicted.

Achilles is all of these things. He mopes on the flanks of the Greek army with his own independent band of fighters, carrying out a separate diplomatic policy, kind of like Ollie North. He thinks Agamemnon is a poor leader with bad strategy and doesn't really get worked up until his beloved cousin Patroclus (Garrett Hedlund) is killed in battle.

Has he read the Iliad? Achilles does these things in the movie because that's what he does in the poem. He spends half the war sulking in his tent because he got in a fight with Agamemnon. And while Achilles wasn't necessarily the most introspective guy in the world, there are certainly several Greek heroes who are conflicted -- Odysseus pretends to be crazy so he won't have to go to war, even though he knows it is his duty.

Anchor: No, it's an easy one.

Oh, whew! Wouldn't want to give a CEO a tough question.
