Denis Villeneuve’s Dune: Part Two stays largely faithful to Frank Herbert’s Dune novel, but the sequel introduces several significant changes to the story and characters.
- Elimination of the Two-Year Time Jump: Dune 2 removes the two-year time leap found in the book, opting for a narrative that picks up directly after the events of the first film.
- Omission of Jamis’ Fallout: While Paul’s killing of Jamis is retained from the book, Dune 2 does not delve into the consequences of his death, omitting the subplot involving Jamis’ wife and children.
- Count Fenring’s Absence: Count Fenring, a pivotal character in the book and advisor to Emperor Shaddam, is notably missing from Dune 2, despite his wife’s inclusion in the film.
- Thufir Hawat’s Complete Exclusion: Thufir Hawat, a significant figure in the novel, is entirely absent from Dune 2, despite his crucial role in the book’s plot.
- Alia Atreides’ Altered Role: Dune 2 diverges from the book by presenting Alia Atreides’ character differently, with the film opting to keep her in Jessica’s womb throughout, rather than showcasing her as a child with adult-like intelligence.
- Exclusion of Chani and Paul’s First Son: The sequel skips over the development of Paul and Chani’s first child, Leto II, and his tragic fate, a significant departure from the book’s storyline.
- Chani’s Integration into the Lisan al Gaib Prophecy: Dune 2 adds depth to Chani’s character by tying her to the Lisan al Gaib prophecy, a departure from the book’s narrative.
- Gurney’s Revenge on Rabban Harkonnen: Dune 2 alters Gurney Halleck’s arc by allowing him to exact revenge on Rabban Harkonnen himself, diverging from the book’s portrayal of events.
- Paul’s Direct Involvement in Baron Harkonnen’s Death: The film changes the book’s ending by having Paul personally kill Baron Harkonnen, departing from the novel’s version where Alia is responsible for the act.
- Variation in Feyd-Rautha’s Death: Dune 2 depicts Feyd-Rautha’s demise differently from the book, opting for a more brutal fight scene between him and Paul.
- Challenge to Paul’s Ascension by the Great Houses: Unlike the book, Dune 2 introduces a plot point where the Great Houses challenge Paul’s ascension to Emperor, setting up potential future conflicts.
- Chani’s Departure: The sequel concludes with a departure from the book, as Chani storms off after Paul’s proposal to marry Irulan, leaving her fate uncertain.
These significant deviations from the source material contribute to the unique interpretation of Herbert’s novel presented in Dune: Part Two.
