Spoilers ahead for the book versions of Dune Messiah (1969) and Children of Dune (1976). Director Denis Villeneuve is confirmed to be working on the upcoming third Dune movie, a sequel to 2024’s Dune: Part Two. In terms of length, Dune Messiah is much shorter than Dune, meaning there are far fewer pages to adapt, hence, only one movie. Is Dune 3 the last Dune movie? Messiah is certainly the last Dune novel in which Paul is a main character, though he does appear in the third book, Children of Dune.
