The Odyssey is a fantasy tale, so I'm not sure why people are getting hung up on the accuracy of the armour. It's an epic poem that features fantastical creatures like the Cyclops. It was never meant to be a historical account.
I'm certainly intrigued on how Nolan will handle this. Will he go all out on the fantastical elements, or will they be more grounded
The premise of the story certainly fits the theme of time that Nolan is known for.
Nolan should have made the Iliad and Odyssey back to back.
