Dune: Part Three trailer pits Paul against a conspiracy and Chani's anger, in theaters December 18, 2026
- The first full trailer for Dune: Part Three adapts Frank Herbert's Dune: Messiah and is set roughly 17 years after Part Two, per Denis Villeneuve, with a theatrical release on December 18, 2026.
- New cast members include Anya Taylor-Joy as Paul's younger sister Alia, Robert Pattinson as the villainous Scytale, Isaach de Bankolé as Farok, Nakoa-Wolf Momoa as Leto II Atreides, and Ida Brooke as Ghanima Atreides; Jason Momoa returns as the reanimated ghola Hayt, who tells Paul he is "way beyond redemption."
- The trailer opens on an argument in which Chani tells Paul "I trusted you," saying he promised never to take power in his own name but instead waged galactic war and destroyed thousands of worlds to become emperor.
- The conspiracy includes Princess Irulan and Scytale, though Irulan objects when Scytale says he intends to kill Paul for "regime change," telling him "You've just signed our death warrants"; Hayt's peace proposal is described as meant to destroy Paul.
- Chani appears on the dunes of Arrakis seemingly summoning a sandworm, and the trailer closes with a remorseful Paul asking forgiveness for what he has done.
