Zendaya's Chani was always going to have a pivotal role in Dune: Part Three and how Denis Villeneuve's wraps up his sci-fi trilogy. The first two movies, especially Dune: Part Two, fleshed out their relationship beyond what was in Frank Herbert's original book. His sequel book, Dune Messiah, which Dune 3 is largely based on, makes Chani a central figure in Paul Atreides' arc. For that reason, and Zendaya's increasingly growing stardom, it always made sense that Villeneuve would alter aspects of Chani's story to elevate her story. The director's adaptations have been largely faithful to the source material, only straying far from the books to improve characters, streamline stories, or emphasize certain themes. All of Dune 3's marketing has highlighted the elements of Chani's story that Dune book readers would expect. Her story looked to be focused on reuniting with Paul after Dune: Part Two's ending, them starting a family together, and her supporting Maud'Dib, even if some friction remained. It all looked mostly by the book, other than moving up the birth of Chani and Paul's twin children, Leto II and Ghanima. Every preconceived expectation for Chani's role is thrown out the window with Dune 3's final trailer. The epic 2-minute and 40-second trailer provides a much fuller look at what's in store for Zendaya's character, confirming she is not the completely loyal Fremen with an unwavering love for Paul from the books. Villeneuve has rewritten the story to make her a central antagonist. Dune 3 Has Made Chani A "Villain" A conspiracy to overthrow Paul as Emperor is the main story at the heart of Dune Messiah, with Irulan teaming up with Scytale, Edric, and Reverend Mother Mohiam to plot Maud'Dib's demise. It's through this plot that Duncan Idaho returns as a ghoula named Hayt, and practically every piece of political deception and maneuvering is born from it in the book. Dune 3 is faithfully bringing most of those elements to life, but with the twist that Chani is also involved. The trailer confirms this information as Paul uses the Voice to force Irulan to tell him everything she knows, and she says, "There will be an assassination attempt, and Chani is involved." While that could be potentially chalked up to a Bene Gesserit lie, the rest of the trailer makes it clear Paul's legal wife is being truthful. Chani is seen meeting Scytale in the Arrakis deserts later on, and he questions if she's ready for the events that are about to begin, prompting her response, "Fremen keep their word." She is fully on board with the plot to take down her lover of her own free will, with her and Paul's conflict appearing to be the final confrontation in Dune 3. This makes Chani the "villain" to Paul's "hero," even if those descriptors may fit better when flipped. It's a major change from Chani's role in Dune Messiah. In the book, she is completely loyal to Paul and unaware of the conspiracy against his life. Instead, her role revolves around Irulan drugging her so that she can't get pregnant and produce an heir for Paul's empire. Paul is left trying to carefully navigate the futures he sees to try and keep Chani alive as the plot unfolds. After hiding the twist for the entirety of the marketing campaign so far, the reveal of Chani's true role is a seismic change for the Dune franchise. Given how such a drastic departure from the source material could irk sections of the Dune fandom, though, it is understandable to let the cat out of the bag now, especially if it is not played for a twist in the movie itself. Chani's Villain Arc Makes Sense After Dune: Part Two's Ending It's important to note that Villeneuve isn't altering Chani's story so significantly just for the sake of surprise. The marketing team wouldn't have unveiled the new arc in that case. This decision instead has seemingly been born naturally after where Dune 2 left Chani. Villeneuve's sequel ended in a similar way to Herbert's original novel, with Paul accepting a marriage proposal to Irulan to secure the throne. However, the movie had this happen without Paul really communicating with Chani, leaving her angry, heartbroken, and confused. She is last seen in the desert alone, showing the start of a divide between the once inseparable couple. Chani going right back to Paul and having a happy-ish life with him would have been true to the book, but it would have felt like a bit of a betrayal to Zendaya's characterization. She and Villeneuve have imbued Chani with much more urgency, determination, and power. This version is a born and raised fighter, and that's what she's going to do after Paul's betrayal. This is communicated through Dune 3's trailer, where Paul says, "After years of combat, I'd become the oppressor Chani had sworn to fight." It makes much more sense for the character we've seen in the last two movies to continue fighting for the betterment of all Fremen and Arrakis, even if that means standing opposed to the person she thought was going to give them a better future. Dune 3's New Chani Story Confirms A Different Fate Than The Books Warning: Contains spoilers for Dune Messiah!By changing Chani's story in this way, it is confirmed that Dune 3 won't give the character the same fate she received in the book. In Messiah, Chani dies during childbirth after Paul loses his physical eyesight and starts to learn he no longer knows what the future holds. Dune 3 is confirmed to take place 19 years after Dune 2, with Chani already having given birth to Leto II and Ghanima. They are teenagers in the film and are seen interacting with both Chani and Paul. Clearly, their mother did not die while giving birth to them. With that possibility in the rearview mirror, Dune 3 is going to give Chani a completely new ending. It could still end in death, but perhaps as part of the conspiracy plot she was involved in. There's even the tragic option of Paul killing her to preserve House Atreides' rule. Whatever exactly happens, it will be completely different from what Herbert did in the books. She'll either live to see Dune 3's different ending for Paul or perish as part of this fresh storyline. Paul Vs. Chani Is A More Fitting Way To End Denis Villeneuve's Dune Trilogy Book purists may resist the direction Villeneuve is taking the end of his Dune trilogy, but the finale revolving around Paul versus Chani is the right move for this adaptation. He's carefully constructed both characters to be strong-willed and have a sense of doing what they believe is best. In the past, they aligned on what that meant. Dune 3 exploring how they act in conflict with each other is exciting. Their showdown is also coming from a deeper place than a simple disagreement. Chani says in the trailer that "I was doing this for our children," while Paul says, "I'm doing this for you." In their own ways, they are both taking actions they felt were necessary for the betterment of their family's future. It's also clear that despite the differences they have and the actions they've taken, Dune 3 is going to show just how complicated this situation and their relationship is. The confrontation on the sandworm shows an emotional embrace as they come to know they're pitted against each other. It's a brilliant way to wrap up the Dune trilogy after Villeneuve put so much emphasis on their relationship in Dune 2, where "She becomes our moral compass," according to the director in a 2024 interview. That makes the "villain" arc for Chani a fascinating development, as it could really be a way for Dune: Part Three to make sure audiences leave the trilogy knowing that Paul is not a hero.
