I still don't understand why Christopher Nolan did this with The Odyssey and it's casting while He did so much research when he was making Oppenheimer, Dunkirk , every little detail like look , walk , how the characters should talk , but in this movie why he left the story's most important character Helen of Troy like this . Helen of Troy is the reason for the fall of Troy , The Trozen Horse war ... Lupita Nyong'o is very talented , she is a very good actress .. why did Christopher Nolan choose her?? Still don't understand
