“Dune 3” jumps 17 years into the future—Paul and Chani are no longer aligned, war is on the horizon, and Robert Pattinson enters the saga as a shape-shifting wildcard. The desert just got even stranger.

“Dune: Part Three,” inspired by Frank Herbert’s “Dune: Messiah,” tells the story of what happens after Paul — the warrior prince and chosen one — defeats the Harkonnens and becomes Emperor, embracing his role as the Fremen’s messiah and initiating a holy war. He also marries Princess Irulan (Florence Pugh) for political power, causing Chani to abandon him. The teaser features explosive glimpses of the galactic conflict that follows, as well as the internal battles that plague Paul.
