Homer’s Odyssey vs. Christopher Nolan’s Film: Changes from Poem to Screen
Comparison has long been charged with the theft of joy, but there’s a case to be made for the joy that comes from comparison. Like any film adaptation, Christopher Nolan’s The Odyssey (2026) makes a few cuts and alterations to Homer’s 12,109-line epic. While the plot of the film broadly resembles that of the poem, Nolan takes creative liberties in reinterpreting specific episodes, characters, and some of the stranger—and more exciting—parts of the poem. That provides at least a few opportunities to contrast the two, in service of both the film lover and the enthusiast of Greek mythology. Even though the Odyssey has been around for more than 2,500 years now, be warned that spoilers lie ahead.

Mount Olympus is awfully quiet
As mortals battle or set out on adventure in the Iliad and the Odyssey, gods often intervene in various ways, such as dispensing advice or retribution. The most prominent divine figure in the Odyssey is Athena, the goddess of military strategy and wisdom, who favors Odysseus because of his sharp wit and resourcefulness. Without Athena entreating Zeus to secure his release, Odysseus might have been Calypso’s captive forever. Among other forms of assistance, Athena disguises him, helps him defeat Penelope’s suitors, intervenes to establish peace when the suitors’ relatives thirst for revenge, and accompanies his son Telemachus to Pylos and Sparta in disguise. On the other hand, it is Poseidon’s wrath against Odysseus for blinding his son, the Cyclops Polyphemus, that makes Odysseus’s journey home so difficult and tortuous. The divine messenger Hermes also makes a couple of notable appearances in the epic.

While minor goddesses such as Circe and Calypso are important characters in Nolan’s version too, the Greek gods of Mount Olympus are either invisible or completely absent. Athena’s existence is ambiguous in the film: She is less a divine benefactress and more a manifestation of Odysseus’s own guilty conscience about his role in the brutal sacking of Troy. This interpretation comes into play because the film gives Athena the physical features of a priestess who is decapitated during the fall of the city. In Nolan’s film Zeus and Poseidon never appear explicitly, and their acts are similarly ambiguous, attributable to natural phenomena just as easily as to divine agency. Hermes doesn’t even get a mention.
On several occasions characters in the film invoke Zeus’s law as a sacred code that guarantees hospitality and protection for guests, travelers, and strangers—one of the film’s central themes. While Homer’s Odyssey does not refer to it precisely as Zeus’s law, it is essentially the concept of xenia, the custom of hospitality believed to be enforced by Zeus. The epic features several practical instances of its application and the consequences of its violation.
Odysseus’s adventures go a little differently
The film makes quite a few changes and omissions to Odysseus’s seafaring adventures. In the poem, after leaving Troy and briefly sacking the coastal city of Ismarus, the Ithacans arrive at the island of the Lotus-Eaters. There, Odysseus’s men feed on the fruit of the mysterious lotus plant, which makes them forget about home and lose their will to return. Odysseus, who does not eat the fruit, has to forcibly drag them back to the ship. This episode is skipped over in Nolan’s adaptation; instead, Calypso feeds Odysseus amnesic lotus flowers to suppress his memories of home and keep him on her island for seven years.
Their next adventure takes Odysseus and his companions to the land of the Cyclopes. In Homer’s text there are multiple one-eyed giants in this lawless country, but Nolan does not give any suggestion that there is any more than one in the film: Polyphemus. Both versions have the soldiers steal into his cave when he’s away and Odysseus stubbornly decide to wait for the inhabitant in hopes of being welcomed as a guest as per customary rights (xenia) safeguarded by Zeus. Though he is more conversant in Homer’s Odyssey, Polyphemus cares little for custom or Zeus in either version as he gobbles up a few soldiers and traps the rest in the cave with a massive boulder. Both poem and film then have Odysseus hatch an escape plan, though that of the former has a few more steps. In Homer’s poem Odysseus gets Polyphemus drunk on special wine, tells him his name is Nobody, and blinds him with a fire-hardened wooden stake when the Cyclops falls asleep. Polyphemus shrieks for help and his neighbors respond, but when he tells them that Nobody is trying to kill him, they dismiss him and leave. The soldiers then exit the cave by clinging to the bellies of his sheep when they go out for grazing, evading Polyphemus’s touch. As they are escaping, Odysseus boastfully reveals his real name—an act of hubris that allows Polyphemus to pray to Poseidon to unleash his fury upon the hero and seals the fate of his crew. In Nolan’s adaptation the Cyclops does not speak to the soldiers, wine is not involved, Odysseus never fools Polyphemus with a fake name, and the soldiers escape with hay on their backs, not hidden on the underside of sheep. Odysseus does not taunt the Cyclops with his words but does needlessly strike him with an arrow as he flees with his men.

The film omits an episode in which the crew reaches the island of Aeolus, the divine controller of the winds, who gives Odysseus a bag of winds to help him get home. When they are tantalizingly close to Ithaca, Odysseus falls asleep, and his men open the bag hoping to find gold and silver, only to be driven all the way back to Aeolus’s island, where they are then turned away for being hated by the gods. The film instead skips to the next adventure: the cannibalistic giants known as the Laestrygonians. The movie does not touch on their dietary preferences and puts them in medieval-style armor as they cut down many of Odysseus’s crew amidst a forest with shifting trees. The Laestrygonians also destroy all but one of the Ithacans’ ships (12 in the poem, 3 in the movie) in both versions. In the film the survival of Odysseus’s ship seemingly comes down to luck, while in the poem his ship makes it out because he happens to moor it outside—rather than within—the narrow-mouthed harbor where the others parked.
The sole surviving ship next arrives at the island of Aeaea, the home of the sorceress Circe. In the poem Circe warmly invites a contingent of Odysseus’s starving crew for a meal and then turns them into pigs with magic potions. Only second-in-command Eurylochus suspects treachery and returns to tell Odysseus of what happened. By consuming an herb called moly, on the advice of Hermes, Odysseus is immune from Circe’s enchantment. She convinces him to sleep with her, and he convinces her to turn his men back to human form. For a year Odysseus and his shipmates stay on the island in relative comfort until he finally requests Circe to help them go home. She advises him to take a detour to the house of Hades and seek guidance from the spirit of the blind prophet Tiresias. In the film the crew spends hardly a day on Circe’s island. Eurylochus does not escape being turned into a pig, nor is there any mention of moly. Instead, Odysseus pieces together Circe’s designs from scattered clues and convinces her to change his men back by threatening to kill an imprisoned raven—her sister in bird form. While there are some stories of women being transformed into birds, none appear in the Odyssey or in relation to Circe. The raven is likely her sister Pasiphaë; ancient texts do not present them as in conflict, though modern adaptations, such as Madeline Miller’s Circe (2018), sometimes do. In the film Odysseus and Circe do not have a sexual relationship. As the film also does not adapt the death of the young soldier Elpenor—who dies after getting drunk and falling off Circe’s roof—the crew never returns to Circe’s island to bury him, and she does not later give Odysseus advice about the Sirens and Scylla and Charybdis as she does in the poem.
At the border of the underworld, the poem reacquaints Odysseus with several legendary characters among the dead, including Elpenor, Achilles, Ajax, Agamemnon, Heracles, and Odysseus’s mother. In the film, apart from Tiresias, he only meets Sinon—a character who does not appear in Homer’s Odyssey—and Agamemnon. Tiresias’s advice in the film tells Odysseus what he must do to get home: resist the tempting song of the Sirens, choose the lesser evil between Scylla and Charybdis, and prevent his men from killing the cattle of the sun god, Helios. In the poem Tiresias only warns him against killing the cattle, though he also tells him he will have to kill Penelope’s suitors when he gets back and then set out on an inland journey with an oar to finally calm Poseidon’s wrath.
The film makes only a few changes to the following episodes. Odysseus does not lose any crew members to the Sirens in the poem, but one sailor removes the sound-dampening wax from his ears in the film and swims to certain death. In the poem, Odysseus tells his sailors only to avoid Charybdis but purposely does not tell them that it means giving up six lives to Scylla; in the film, he deceives his own crew into sailing toward Scylla.
After his crew consumes Helios’s cattle and their ship is torn apart by a tempest ostensibly precipitated by Zeus, the movie offers little explanation for how Odysseus survives. The epic, however, describes how the ship was swept back to Charybdis. Odysseus survives by latching on to a fig tree and then drifting for nine days on broken planks from the ship until he reaches Calypso’s island.
The poem’s framing device involving the Phaeacians is elided in the movie, and Odysseus washes up directly on Ithaca’s shores after leaving Calypso’s island on a raft—therefore also skipping the magical protection he receives from the goddess Ino that keeps him from drowning. The film also does not include Calypso’s famous indictment of the Olympians and their policing of female sexual agency.
Contrasting homecomings and endings
The film condenses much of the action after Odysseus’s return to Ithaca and makes major changes to the ending. Athena’s role in disguising Odysseus and even fighting alongside him on occasion is completely discarded in the film; Odysseus must make his way home to his wife Penelope using his own wits. Dressed as a beggar, he does not tell the swineherd Eumaeus and later Penelope different, complicated stories of what brought him to Ithaca, as he does in Homer’s version. Instead he consistently pretends to be a Trojan War veteran and uses Sinon’s name.
There are plots by Penelope’s suitors to assassinate Telemachus in both the poem and the film, though they play out differently. In Homer’s epic the suitors plan to ambush his ship in a strait as he returns from Pylos and Sparta. In the film Telemachus visits Menelaus and Helen of Troy in Sparta and, on the way home, is ambushed at a temple. He is saved by Odysseus in another significant departure from the source. In the film Telemachus deduces Odysseus’s identity unlike in the epic, in which Odysseus reveals it himself.
When Odysseus does finally fight the suitors in the epic, he does so alongside Telemachus, Eumaeus, and Philoetius (a loyal herdsman). In the movie he seems intent on fighting alone, saying that killing the suitors would result in exile—a fate he does not want for Telemachus. The idea of exile as punishment does not exist in Homer’s poem but may be inspired by 1st-century ce essays attributed to Plutarch: In “Greek and Roman Questions” Neoptolemus, son of Achilles, decides as arbiter that Odysseus should be exiled for murdering the suitors.
Odysseus’s slaying of the suitors is more of a massacre in the poem than in the film, as the seasoned hero of the Trojan War rampages uninjured through the mostly unarmed and ambushed suitors. Athena aids him by deflecting the suitors’ projectiles and making them miss their mark. In the film Odysseus fights completely alone and sustains much more damage before emerging victorious. Antinous, the most prominent and mean-spirited suitor, is the first to die at Odysseus’s hands in the poem but the last in the film. In the poem, after most of the suitors have been killed and the remaining beg for mercy, Telemachus also hangs the unfaithful housemaids who had consorted with the suitors either willingly or by force. They are not hanged in the film. Another episode omitted from the adaptation is Penelope’s test of Odysseus, wherein she commands a housemaid to move their marriage bed only to see how Odysseus reacts. He passes her test when he furiously expresses his disapproval, saying he had built the bed himself around a living olive tree.
After the massacre of the suitors in the poem, their relatives rise in anger against Odysseus. A brief skirmish ensues in which Antinous’s father is also killed, but Athena puts an end to the fighting and makes both sides swear oaths to restore peace in Ithaca. The film’s ending sees Odysseus being exiled for the murders and then embarking on a voyage west with Penelope to honor his fallen soldiers, with Telemachus taking over as king.
The film makes much of “the people from the sea,” heralded as the mysterious agents of an impending civilizational collapse. This reference is not to anything Homeric but rather the historical Sea People, seafarers who were known to carry out raids in the eastern Mediterranean region and were traditionally thought to have brought about the Late Bronze Age collapse, a period when trade connections declined and many large settlements were destroyed or abandoned. Modern scholarship disputes this claim and increasingly attributes the decline of civilizations such as Mycenaean Greece about this time to a cocktail of invasions, internal unrest, environmental pressures, and the breakdown of regional trade networks. The film posits that the returning soldiers of the Trojan War themselves are the shadowy people from the sea. Bronze Age Greeks are among the groups tentatively identified with the Sea People.
Big and small character changes
Nolan makes quite a few changes to characters and their traits in the film. Some are relatively minor: Eumaeus is not blind in Homer’s Odyssey, for example. Some characters were dropped as the film discards associated storylines, such as that of the Phaeacian princess Nausicaa. Odysseus’s father, Laertes, similarly does not get his tearful reunion with his son in the film. One of Nolan’s more intriguing changes is his choice to make Helen of Troy and Clytemnestra identical twins. In Homer’s epic they are half-sisters but not twins, though other accounts do depict them as sisters born from the same egg. The film also shows Helen with a scar on her face—presumably the result of violence by her husband Menelaus. The poem does not describe such a scar. Menelaus’s reference to the phrase “the face that launched a thousand ships” in the film does not appear in Homer’s work either; the popular quote actually originates from Christopher Marlowe’s Doctor Faustus (published in 1604). Nolan also borrows the character of Sinon—a young soldier left behind by Odysseus to convince the Trojans that the wooden horse is an offering to Athena—from Virgil’s Aeneid (written from about 30 to 19 bce). The film also invents an original backstory for Sinon linked to Antinous: Sinon is shown to be a shepherd boy persuaded by the craven Antinous to join the Trojan War in his place.
Perhaps no change in the film is as consequential as the profound reworking of Odysseus’s temperament and motivations. As rendered by Homer, Odysseus is defined by his guile and his ability to lie liberally and effectively to achieve his goals—no matter how deplorable they may sometimes be. At the same time Odysseus is brash, arrogant, and given to prideful boasting, which gets him into trouble with Poseidon and dooms his crew. Nolan’s Odysseus, on the other hand, is more considerate, watchful, and modest, hardly ever making a move out of self-interest. While his intellect is still central to his character, his guilt for his role in Troy’s destruction preys on his conscience throughout the film and becomes the character’s emotional core.
