Christopher Nolan Confirms Casting Twist for The Odyssey, With One Actor Playing Dual Roles

Christopher Nolan has confirmed a casting twist for his upcoming “mythic action epic,” The Odyssey.

Lupita Nyong’o plays both Helen of Troy and her sister, Clytemnestra, in The Odyssey. Confirmation comes from a profile of the celebrated director in Time magazine, which also includes Nolan’s defence of the The Odyssey from complaints around historical accuracy.

The Odyssey is an adaptation of Homer’s foundational saga of the same name, one of the major epics of ancient Greek literature. It stars Hollywood heavyweights such as Matt Damon, Tom Holland, Anne Hathaway, Robert Pattinson, Zendaya, and Charlize Theron. Helen of Troy, or Helen of Sparta, is a figure in Greek mythology renowned as the most beautiful woman in the world. Her abduction by Paris of Troy sparked the decade-long Trojan War.

According to Time magazine, Nolan “complicates” the relationship between Helen of Troy and her husband, King Menelaus of Sparta, played by Punisher actor Jon Bernthal. We don’t learn more about what that means, exactly, but the Time piece confirms Nyong’o also plays Helen’s sister, Clytemnestra. Clytemnestra is married to King Menelaus’ brother, Agamemnon, who is played by Benny Safdie. Time characterises Clytemnestra’s marriage to Agamemnon as “acrimonious,” but again, we don’t know exactly what that means. The upshot is we have the same actress playing two sisters, each of whom is married to one of two brothers. Sounds like a fun recipe for some Greek family drama!

But why is Lupita Nyong’o, who played Nakia in Black Panther, Maz Kanata in Star Wars: The Force Awakens, and Sam in A Quiet Place: Day One, playing a dual role in The Odyssey? Nolan hasn’t said, but it’s a somewhat surprising decision. In Greek mythology, Helen and Clytemnestra are half-sisters, not identical twins. Helen and her brother Pollux are children of Zeus, while Clytemnestra and her brother Castor are children of Tyndareus. All four are children of the same mom, Leda, who was seduced by Zeus while in the form of a swan. According to the myth, Leda gave birth to two eggs, one fathered by Zeus and from which Helen and Pollux emerged, and one fathered by Tyndareus and from which Castor and Clytemnestra emerged. Castor is the mortal half twin brother of the immortal Pollux. Perhaps Nolan has taken that aspect of the myth and applied it to Helen and Clytemnestra, converting the two from half-sisters to identical twins?

Time also mentioned that Argos the Superdog (sorry, that’s another superhero movie!)… Argos, Odysseus’ loyal dog, has an expanded role in the movie. Nolan recently described The Odyssey as “the ultimate dog story,” so that tracks. Expect to see Odysseus and his son Telemachus, played by Spider-Man star Tom Holland, spend plenty of time together, too.

Argos was recently revealed, by the way, in a new The Odyssey trailer that also offered a first look at Charlize Theron’s Calypso, a nymph who lived on the island of Ogygia, and Robert Pattinson’s villainous Antinous, one of Penelope’s suitors.

The trailer revealed more of the fantastical elements we can expect to see, including a better look at the Cyclops Polyphemus, a battle with armored giants in a forest, and a desperate attempt to sail safely past a whirlpool.

The Odyssey hits theaters on July 17, 2026.
