Something similar happened with the trailer for Christopher Nolan’s upcoming adaptation of Homer’s “Odyssey,” in which Matt Damon plays Odysseus. (“After years of war, no one could stand between my men and home,” he sets up in a voice-over.) Many viewers immediately took umbrage. The problems weren’t about the familiar story beats that flit by, like the Cyclops entering his cave or dead warriors rising to face the living. The issue was historical accuracy. Dozens of videos, posts and articles boasting millions of views object that the austere cuirasses — “drab leather nonsense,” in one user’s words — and red-plumed helmets worn by Odysseus and his crew do not resemble actual Bronze Age Greek armor circa 1200 B.C. The gray, Kevlar-like helmet we see atop Agamemnon’s head, meanwhile, has been compared to a leftover prop from Nolan’s Batman series and “like a toy helmet” that viewers fear will “break the immersion.” They also noticed that Nolan put Odysseus on a Viking-style boat rather than an ancient Greek penteconter and, in some shots, substituted Scottish isles, with their local flora, for Mediterranean ones.
