Warner Bros. has released a new trailer for Denis Villeneuve’s Dune: Part Three, and the marketing machine is now selling the part Frank Herbert cared about most: what happens after the messiah wins.
The film is scheduled to reach theaters on December 18, 2026. According to Villeneuve, it is set roughly 17 years after Dune: Part Two and draws from Herbert’s Dune: Messiah, the novel that turns Paul Atreides’ victory into a problem with a body count.
In the films so far, Paul Atreides, played by Timothée Chalamet, survived the fall of House Atreides, joined the Fremen on Arrakis and became the figure their religious machinery had been primed to accept. By the end of Dune: Part Two, he had defeated the emperor’s champion, demanded Princess Irulan as his wife and launched a holy war after the Great Houses refused his rule. Chani, played by Zendaya, refused to kneel and left on a sandworm.
Paul’s empire is the problem now
The official premise says Paul, now known and feared as Muad’Dib, rules as emperor of the known universe while facing hostile political houses, devotion from fanatical Fremen and a plot forming inside his own circle. It also points to danger aimed at Chani and the unborn heir to Paul’s dynasty.
The trailer frames that collapse through Chani’s anger. She tells Paul, “I trusted you,” and says he promised not to seize power in his own name. The footage cuts between that confrontation, earlier moments between them and scenes of battle. Chani accuses Paul of waging galactic war and “destroyed thousands of worlds” to become emperor.
That is the useful thing about Messiah as source material: the victory parade is already over. The trailer is less interested in the spice-rush fantasy of conquest than in the people left calculating how to survive Paul’s reign, including the woman he alienated while becoming exactly what he said he would resist.
Hayt, Scytale and a peace offer with teeth
The trailer also brings back Jason Momoa, although not as Duncan Idaho in the ordinary sense. He returns as Hayt, a ghola, meaning a reanimated figure who retains Duncan’s memories. In the footage, Hayt says Paul is “way beyond redemption” and says he has come with a peace proposal. He also warns that the proposal is designed to destroy Paul.
The conspiracy appears to involve Princess Irulan, played by Florence Pugh, and Scytale, played by Robert Pattinson. Scytale is described as a villain plotting to remove Paul from power. The trailer shows Irulan objecting to Scytale’s plan to kill Paul for “regime change,” calling him an idiot and warning, “You’ve just signed our death warrants.” Given Paul’s prescient abilities after Dune: Part Two, plotting against him is less a chess match than volunteering to be the board.
Chani may also be acting against Paul, though the trailer leaves that in suggestion rather than confirmation. One scene shows her on the dunes of Arrakis, apparently calling a sandworm, which charges toward her before stopping in front of her.
The returning cast includes Chalamet, Zendaya, Pugh, Rebecca Ferguson as Lady Jessica, Josh Brolin as Gurney Halleck and Javier Bardem as Stilgar. New cast members include Anya Taylor-Joy as Alia Atreides, Robert Pattinson as Scytale, Isaach de Bankolé as Farok, Nakoa-Wolf Momoa as Leto II Atreides and Ida Brooke as Ghanima Atreides.
The trailer ends with Paul asking forgiveness for what he has done. Warner Bros. is selling remorse. Herbert, less politely, built a sequel about consequence.
