Cast and Characters

Timothée Chalamet headshot
as Paul Atreides
Chalamet plays Paul as a 15-year-old whose adolescence is being interrupted by the gradual recognition that the prescient dreams he has been having are not hallucinations. The performance is calibrated for restraint rather than action-hero swagger: Paul listens, watches, and slowly absorbs that the universe he was born into is much more dangerous than his father has been able to tell him. His pain-box scene with Charlotte Rampling's Reverend Mother is the role's signature, and Chalamet plays the suppressed agony as a private negotiation rather than a performed one.
Rebecca Ferguson headshot
Rebecca Ferguson
as Lady Jessica Atreides
Ferguson anchors the film's mystical register. Lady Jessica is the Bene Gesserit concubine who disobeyed orders to bear Leto a son rather than the daughter the order had instructed, and Ferguson plays the role as a woman carrying the weight of that disobedience in every scene. Her use of the Voice — the Bene Gesserit's commanding hypnotic register — is calibrated as a physical discipline rather than as visual-effects trick, and her late-act desert scenes with Chalamet are some of the most quietly devastating exchanges in the picture.
Oscar Isaac headshot
Oscar Isaac
as Duke Leto Atreides
Isaac plays Duke Leto as a man who knows the imperial order assigning him to Arrakis is a trap and accepts the assignment anyway because the alternative is to be unmade by the emperor publicly. The performance is in the noble-house register the role demands — measured, courteous, fatherly — but Isaac keeps Leto's fatalism just visible enough underneath that the audience reads the trap from the same vantage point Leto is reading it. His scenes with Chalamet on the family balcony are the film's emotional centre.
Jason Momoa headshot
Jason Momoa
as Duncan Idaho
Momoa plays Duncan Idaho — the Atreides house's senior swordmaster and Paul's surrogate older brother — with a leather-jacket warmth that the rest of the largely austere cast deliberately does not match. The role functions as the film's most physical performance, and Momoa choreographs the action scenes (the desert-camp reconnaissance, the final defensive stand inside the research station) with a credibility the script's mythological register would otherwise risk losing. His farewell-hug scene with Chalamet on the spice-harvester landing pad is the picture's most-quoted character beat.
Stellan Skarsgård headshot
Stellan Skarsgård
as Baron Vladimir Harkonnen
Skarsgård plays the Harkonnen Baron under heavy prosthetic and suspended in a personal gravity-suspension rig — the result of the character's grotesquely-engorged physique in the source novel. The performance is held mostly in voice and eyes; Skarsgård lets the Baron's intelligence sit just visibly underneath the prosthetic, and his oil-bath conference scene with Glossu Rabban is the picture's most direct staging of pure-corporate-villainy register without tipping into camp.
Stephen McKinley Henderson headshot
Stephen McKinley Henderson
as Thufir Hawat
Henderson plays Thufir Hawat, the Atreides Mentat — a human computer trained in the post-AI Imperium where machine-intelligence has been banned and certain humans have replaced it. The role is largely advisory, and Henderson plays Hawat as a man whose entire professional value is the assembly of conclusions from incomplete information. The performance is quiet, watchful, and structurally essential; he is the character whose absence from the second half of the film is one of the picture's quiet costs.
