Dune: Part Three's newest trailer highlights the dramatic rift between Paul Atreides (Timothee Chalamet) and Chani (Zendaya).

Set two decades after Dune: Part Two, Paul has been corrupted and consumed by power. He's now a ruthless emperor with devoted followers, but his brutal leadership has also pushed away those he loves. The tensions between Paul and Chani have led to the latter seemingly teaming up with Scytale (Robert Pattinson), in an effort to dethrone and kill Paul. Paul will also go up against Hayt, a clone of his former friend, Duncan Idaho (Jason Momoa).

Although there are more stories in the Dune universe that could be adapted, Dune: Part Three is being billed as the "epic conclusion" of this saga. Director Denis Villeneuve has expressed zero interest in helming more Dune films and has instead set his sights on the next James Bond movie. Although Dune: Part Three is an adaptation of the novel Dune Messiah, it's possible that Villeneuve will take some liberties with this story to make it a definitive finale.

Additionally, new footage from Dune: Part Three will be attached to 70MM IMAX screenings of The Odyssey next weekend. It's unclear what will be shown, but it sounds similar to how Christopher Nolan attached an extended sequence from The Odyssey to IMAX screenings of Avatar: Fire and Ash last year.

Dune: Part Three will hit theaters on December 18, 2026. It will go head to head with Avengers: Doomsday at the box office, though Dune: Part Three will have the benefit of a exclusive IMAX run for an unknown number of weeks.
