The Odyssey is just much more fun- sex, monsters, shipwrecks, swashbuckling, and a big final shootout. The Iliad is brooding, deep, and a bunch of dudes being their worse selves because they have been stuck on a shitty beach they never wanted to go to anyway.
I love the Odyssey, it is a foundational story and basically all incredible journey/hero trying to go home stories are just covers. I want to know how Nolan treats Odysseus. The Greeks treat him as the most Greek of all heroes, admiring his cleverness and resourceful pragmatism. The Romans felt like he was a tricky, deceitful asshole who bucked their stodgy, do a simple job well attitude. Dante and Shakespeare agreed and the former put him in Hell for being a real dick.
There isn’t a “real” Odysseus, every Western generation creates its own, and I expect Nolan will give us a brooding post-modern guy with lots of inner torment (the Greeks didn’t seem to think he should be bothered by being a selfish prick, and the Gods appeared to come around to the view that he was just smart enough you had to tip your hat).
But he shouldn’t be in a fucking Viking longship.
