Christopher Nolan’s The Odyssey is unlike anything ever put on a movie screen. Shot entirely on IMAX film across oceans, mountains, deserts and ancient landscapes, it is an astonishing feat of physical filmmaking—and arguably the ultimate theatrical experience.But is technical achievement enough to make a great movie?

In this full-spoiler review, we break down Nolan’s adaptation of Homer’s epic, from the Trojan Horse and the Cyclops to Calypso, Ithaca and the slaughter of the suitors. We examine the film’s most significant changes to the original text, including the removal of most of the Greek gods, Odysseus’s altered motivation, the elimination of his defining act of hubris and Nolan’s decision to transform a story about homecoming into one about guilt, trauma and regret.

We also go inside the extraordinary production: enormous IMAX cameras, two-and-a-half-minute film magazines, custom soundproof camera housings, mirrored eyeline systems, real ships and practical environments. Nolan and his collaborators effectively had to invent new filmmaking techniques just to get the movie made.

The result is visually overwhelming and technically historic. But does The Odyssey give us a hero worth rooting for? Did Nolan’s changes weaken Odysseus’s journey? And why does the climactic return to Ithaca feel less emotionally satisfying than it should?
