The Core Houses: A Definitive Cast and Character List (Dune: Part One & Part Two)

The first two films, *Dune* (2021) and *Dune: Part Two* (2024), feature an incredible roster of talent, with many returning favorites and several monumental additions to complete the main arc of the first novel.

Returning Cast (House Atreides, Fremen, and Allies)

• Timothée Chalamet as Paul Atreides: The protagonist, heir of House Atreides, and the Kwisatz Haderach.
• Zendaya as Chani: A young Fremen warrior and Paul's love interest.
• Rebecca Ferguson as Lady Jessica: Paul's mother, a powerful member of the Bene Gesserit.
• Josh Brolin as Gurney Halleck: The Atreides Master-at-Arms, a loyal warrior and Paul’s mentor.
• Javier Bardem as Stilgar: The respected leader of the Sietch Tabr Fremen tribe.
• Stephen McKinley Henderson as Thufir Hawat: The Atreides Mentat.
• Charlotte Rampling as Reverend Mother Mohiam: The Bene Gesserit Truthsayer to the Emperor.
• Stellan Skarsgård as Baron Vladimir Harkonnen: The ruthless, morbid head of House Harkonnen.
• Dave Bautista as Glossu Rabban Harkonnen: The Baron's brutish nephew, known as 'The Beast'.

Key Cast from Dune: Part One (Characters Not Returning for Part Two)

• Oscar Isaac as Duke Leto Atreides: Paul's noble father and the head of House Atreides.
• Jason Momoa as Duncan Idaho: The Atreides Swordmaster and one of Paul’s closest allies.

Monumental New Additions: The Emperor, Princess Irulan, and Feyd-Rautha

The sequel, *Dune: Part Two*, introduced several pivotal characters essential to the political and military climax of the story. The casting for these roles was highly anticipated, bringing in massive star power and fresh faces to the franchise.

New Major Cast for Dune: Part Two

• Austin Butler as Feyd-Rautha Harkonnen: The younger nephew and chosen heir of Baron Harkonnen, a sadistic and lethal warrior who serves as Paul’s ultimate antagonist. Butler’s transformation into the bald, menacing Harkonnen heir was a major talking point.
• Florence Pugh as Princess Irulan Corrino: The daughter of the Emperor and a Bene Gesserit acolyte. Her role is crucial as a political pawn and, later, as the chronicler of Paul’s life.
• Christopher Walken as Emperor Shaddam IV: The Padishah Emperor of the Known Universe, whose fear of House Atreides’ rising power sets the entire conflict in motion. Walken’s gravitas brings a unique presence to the most powerful man in the Imperium.
• Léa Seydoux as Lady Margot Fenring: A powerful Bene Gesserit agent and the wife of Count Fenring. Her actions are critical in setting the stage for the downfall of House Harkonnen.
• Souheila Yacoub as Shishakli: A Fremen warrior who fights alongside Paul and Chani.
• Anya Taylor-Joy in a Key Role (Rumored to be Alia Atreides): Her appearance was a major surprise, confirmed late in the production cycle. While her character was initially kept secret, fan speculation strongly suggests she plays Alia Atreides, Paul's pre-born sister, who is a powerful and unsettling figure in the latter half of the book.

This influx of talent not only elevates the star status of the franchise but also deepens the topical authority of the film by introducing the crucial elements of the *Imperium* and the political machinations of the *Great Houses*. The conflict between the *Atreides* and *Harkonnen* has never been more intense, fueled by the performances of these new additions.

The Future of Arrakis: Casting Rumors for Dune: Messiah (Part Three)

Director Denis Villeneuve has repeatedly expressed his desire to complete a trilogy by adapting *Dune Messiah*, the second novel in Herbert's series. While this third film has not been officially greenlit for production, the success of *Part Two* has made it a near-certainty, leading to intense speculation and casting rumors that point to a fascinating future for the saga. These updates, as of late 2025, are the freshest insights into the *Dune 3* cast.

Potential Returning and New Cast for Dune: Messiah

The plot of *Dune: Messiah* focuses on Paul's reign as Emperor and the consequences of his holy war, making the return of the core cast inevitable, but with significant new roles emerging.

• Timothée Chalamet (Paul Atreides) & Zendaya (Chani): Both are expected to return as the central figures, navigating their complex relationship amidst Paul's political and spiritual burdens.
• Florence Pugh (Princess Irulan): Her role is significantly expanded in *Messiah* as she contends with her political marriage to Paul and her own Bene Gesserit loyalties.
• Anya Taylor-Joy (Alia Atreides): If she is indeed Alia in *Part Two*, her role as the pre-born, adult-minded sister of Paul becomes central and highly controversial in *Messiah*.
• Jason Momoa (Duncan Idaho): In a shocking development for fans of the first film, rumors suggest Momoa will return to the franchise. This would align with the novel’s plot, where Duncan Idaho is resurrected as a *Ghola* (Hayt) by the *Tleilaxu*—a major entity in the *Dune* universe.
• Nakoa-Wolf Momoa & Ida Brooke (Leto II and Ghanima): The most recent and intriguing rumors suggest that the twin children of Paul and Chani, Leto II Atreides and Ghanima Atreides, have already been cast. Nakoa-Wolf Momoa, the son of Jason Momoa, is rumored to play Leto II. These characters become the "real" leads in the later books, setting up a controversial and complex future for the saga.
• Robert Pattinson: A persistent and exciting rumor is that director Villeneuve is eyeing Robert Pattinson for a key villain role in *Messiah*. While the specific character is not confirmed, this would mark another major A-list addition to the already legendary cast.

The journey through the *Dune* saga is a masterclass in epic casting. From the political maneuvering of the *Landsraad* to the desert survival of the *Fremen*, the sheer star power assembled for *Dune* and its sequels is a testament to the enduring power of Frank Herbert’s vision. Fans eagerly await the official confirmation of the *Dune: Messiah* cast, which promises to be just as impactful as the first two films.
