The feast on Arrakis
After arriving on the spice planet, Lady Jessica and Duke Leto Atreides host a banquet for the high society. One of the most important scenes in the novel demonstrates the Atreides family's readiness to expose the corruption of Dune and change the status quo, proving the strength of their new power on the planet. The dinner introduces readers to a host of interesting characters and provides a comprehensive understanding of the political landscape of Arrakis.
While this chapter is crucial for understanding the world’s structure, Villeneuve’s decision to exclude the scene is understandable. Its tension and depth are conveyed through the characters’ thoughts, which would be impossible to show in a movie without voiceover. Rumors even suggest that the scene was filmed but later cut to reduce the already lengthy screen time.
Yue's betrayal and Jessica's suspicion
After the hunter-seeker attack on Paul, the Atreides realize there’s a traitor among them. In the film, Yue, who had not been fully developed as a character, reveals himself just before Leto dies, but in the book, readers discover his intentions much earlier. The novel provides a more extensive understanding of Yue’s motives and portrays a complex picture of suspicions. Lady Jessica finds a note warning her about the Harkonnen conspiracy and suspects the mentat, Hawat, as the traitor. Hawat himself begins to suspect Jessica, and so does Gurney Halleck. When Gurney meets Paul in the desert, he still doesn't know who the true traitor is and wants to kill Jessica. This creates a tense scene between the three characters, which would have been thrilling to see in the film.
Gurney Halleck — not a troubadour
In the films, Gurney pushes Paul to accept his messiah destiny. He is certain, cruel, and continues to serve House Atreides as a military leader until the end. In the book, however, Gurney is a much more complex character with a soft soul. His distinctive traits are his constant playing of the baliset (a fictional stringed instrument), singing songs, and quoting them whenever possible. He gives Paul and Jessica a sense of home, but these touching moments were cut from the movie. In the second part, Gurney does have a musical scene, but it lasts less than a minute and doesn’t fully reveal the character.
Paul's fight with Jamis
The first part ends when Paul kills the Fremen Jamis. Along with him, the old Paul dies, and the messiah is born. The film doesn’t provide any background on Jamis, though in the book, he was a friend and teacher to Paul and only later challenged him to a fight. Chani prepares Paul for the battle by giving him advice on how to win. This confrontation also reveals part of the Fremen culture. According to their traditions, Paul is obligated to take responsibility for the family of his slain opponent. Jamis' wife becomes his servant and later marries the Fremen leader Stilgar.
Paul and Chani don’t have a son
Villeneuve condenses several years of events into just a few months. In the book, Paul takes much more time to adapt to life in the desert, earn the respect of the Fremen, and develop his relationship with Chani. During this period, they have a son, named after Paul. Little Leto dies at the hands of Sardaukar soldiers during their attack on the Fremen.
Paul’s sister Alia doesn’t yet exist
Paul’s sister appears as an adult in his visions and communicates with Jessica from the womb, but she is not yet born. In the book, it is Alia who kills Baron Vladimir Harkonnen with a poisoned gom jabbar needle. Paul never meets his grandfather.
Chani's character
The most significant changes Villeneuve made were to the character of Paul’s lover, Chani. She opposes Paul becoming the messiah and leaves him at the end of the second part. She wants to protect her people and sees no reason to fight for the imposed messiah figure, Lisan al-Gaib. In the book, however, Chani supports Paul and believes in his feelings for her. When Paul decides to enter into a political marriage with Princess Irulan, he promises Chani that he will not engage in romantic or sexual relations with his wife. Chani accepts her place as his concubine, receiving great support from Lady Jessica.
