After watching the Odyssey, I think Nolan deleted a lot of important details that could be pulled from the original Odyssey and other ancient sources. He especially struggles to develop complex female characters. Although Penelope’s character was decent, it was too attached to Odysseus and Telemachus. Further, I would argue that Nolan flattens Clytemnestra very badly, in turn, to shape Agamemnon as a heroic character who was betrayed. However, multiple sources discount this narrative. One important point/version omitted from the movie is that Agamemnon killed Tantalus (Clytemnestra’s first husband) and killed her first child. Of course, because this is not the mainstream version, I could see why Nolan omitted this.
Another aspect was Iphigenia, which the movie omitted the mythological reason for her sacrifice to Artemis (reasons varied, but it was Agamemnon’s fault). Both of these mythological details, I think, deeply weakened the portrayal of Clytemnestra in the movie. Especially the reason why she decided to kill her husband.
I am deeply troubled by how Nolan handled the Circe (or Kirke) scene. This scene was unnecessary and inaccurate to the original text.
The last character, in my opinion, is one of the big lost points of the movie. I don’t understand why Nolan decided to remove/mention Cassandra. If Nolan’s movie is truly anti-war or meant to focus on the collapse of civilization, Cassandra is one of the best characters to illustrate the tragedy of war/collapse of Troy. After Ajax raped Cassandra, she was bought back to Mycenae by Agamemnon. Therefore, it is difficult for me to understand why Nolan would delete all these female characters, to portray Agamemnon in a very heroic and positive light. I am not sure if that is fully accurate according to ancient sources like Orestes, Iphigenia, and the Trojan Women. Indeed, it is a good movie, but…Odyssey should be a Classical poem that includes various complex female characters. Especially when Nolan referenced Emily Wilson’s translation, his movie juxtaposed with Wilson’s interpretation of the story.
