I saw a short portion of the movie Troy today. If I recall correctly one of the scenes which was missing from the movie (but is in the Iliad) is Hector's concern over Andromache losing her freedom. Interesting that the notion of freedom is found so early.
Of course the movie differs from Homer's epic in a number of ways. That is not say that it was a bad movie. I thought that it was pretty good in comparison to a lot of what Hollywood has created out of classical texts.
