I have virtually zero knowledge of The Odyssey as a Greek mythology, save for a few recognisable names like the Helen of Troy, the Trojan War etc. I do want to enjoy the movie to its fullest, and if learning about the plot material is essential to it, then so be it. Is there a good resource giving a summarized version of the plot enough to understand the film? If so, I would really appreciate it if you shared it here.
I’ve read the Odyssey cover to cover several times. Best thing you can do is learning as little as possible before seeing this movie.
