I gave Stef this photo of Irene Papas to use as a makeup guide. I love Papas's eyebrows. (She played Iphigenia and Electra and Clytemnestra in different movies.)
The Narrator is there to explain the curse on the House of Atreus, which falls on Orestes, without shooting all the individual stories of Menelaus and Agamemnon and their relatives.
Well, I will shoot them, but just flashes of them murdering each other.
The point isn't the detailed stories of Orestes' ancestors, they're there to represent the "sins of the fathers," which he and we all inherit.
