Denis Villeneuve’s Dune takes place thousands of years into the future, yet its warriors settle arguments with swords and knives. This is not science fiction forgetting that guns exist. It is the consequence of a military technology that has made conventional firearms unreliable and occasionally catastrophically dangerous.
Released in 2021, Dune: Part One adapts roughly the first half of Frank Herbert’s 1965 novel. It introduces a universe built around dynastic politics, ecological exploitation, religious manipulation and extremely large worms. Villeneuve somehow turns all this into a coherent blockbuster without having characters explain the entire setting while standing beside a holographic map.
The film is patient, visually imposing and often deadly serious. It can also feel like the most expensive opening chapter ever filmed. That incompleteness frustrated some viewers, but after the release of Dune: Part Two, its deliberate construction makes considerably more sense.
Spoiler warning: This article discusses the plot, characters and ending of Dune: Part One.

Although commonly called Dune: Part One, the film was marketed simply as Dune. The “Part One” subtitle appears on screen, quietly confirming that the story will not be wrapping itself up within the next two and a half hours.
What Is Dune: Part One About?
In the year 10,191, humanity is ruled by a feudal interstellar empire. Noble houses compete for wealth and influence beneath the authority of the Padishah Emperor.
The most valuable substance in this civilisation is melange, better known as spice. It extends life, heightens awareness and allows Guild Navigators to conduct safe interstellar travel. Spice can be found only on Arrakis, an almost entirely desert planet inhabited by the Fremen.
House Atreides is ordered to take control of Arrakis from its bitter rival, House Harkonnen. Duke Leto Atreides understands that the appointment may be a trap, but refusing an imperial command is not much of a career option.
His son, Paul, arrives on Arrakis while experiencing increasingly vivid visions of the future. He sees the Fremen woman Chani, glimpses a holy war carried out in his name and begins to suspect that his life has been shaped by forces far beyond his family.
When the Harkonnens return with imperial support, House Atreides is betrayed and nearly destroyed. Paul and his mother, Lady Jessica, escape into the desert, where they must seek acceptance among the Fremen.
The Main Cast and Characters
| Actor | Character | Role in the story |
|---|---|---|
| Timothée Chalamet | Paul Atreides | Heir to House Atreides and the focus of competing prophecies |
| Rebecca Ferguson | Lady Jessica | Paul’s mother and a trained member of the Bene Gesserit |
| Oscar Isaac | Duke Leto Atreides | Paul’s father and ruler of House Atreides |
| Zendaya | Chani | A Fremen fighter who repeatedly appears in Paul’s visions |
| Josh Brolin | Gurney Halleck | Atreides weapons master and military commander |
| Jason Momoa | Duncan Idaho | Swordmaster and loyal Atreides warrior |
| Stellan Skarsgård | Baron Vladimir Harkonnen | The calculating head of House Harkonnen |
| Javier Bardem | Stilgar | Leader of the Fremen community at Sietch Tabr |
| Sharon Duncan-Brewster | Dr Liet Kynes | Imperial ecologist and Judge of the Change |
| Charlotte Rampling | Gaius Helen Mohiam | Bene Gesserit Reverend Mother |
| Dave Bautista | Glossu Rabban | The Baron’s violent nephew |
| David Dastmalchian | Piter de Vries | A Harkonnen Mentat |
| Chang Chen | Dr Wellington Yueh | Physician to House Atreides |
The cast is almost absurdly strong. Even characters with limited screen time feel established through posture, costume and performance. Jason Momoa brings welcome warmth to Duncan Idaho, while Oscar Isaac gives Duke Leto the exhausted dignity of a man who has read the political weather report and found only incoming disaster.
Why Are Swords Used in Dune?
The return of close-combat weapons is one of Herbert’s cleverest pieces of world-building.
Most soldiers and nobles wear personal energy shields. These defensive fields stop fast-moving objects, including bullets and conventional projectiles. A slower object can pass through, which means a skilled fighter must control the speed of a blade as it approaches the shield.
This principle is summarised during Paul’s training with Gurney Halleck:
“The slow blade penetrates the shield.”
A wild slash may be deflected. A controlled thrust, slowed at the correct moment, can pass through and kill. Combat therefore becomes a test of timing, deception and precision rather than pure speed.
The shields do not make every projectile weapon useless. Specialised darts can slow themselves as they reach their target, while artillery still has value against structures and unshielded opponents. Lasguns present an even greater complication. If a lasgun beam strikes an active shield, the resulting reaction can produce an explosion comparable to an atomic detonation. Understandably, people become rather cautious about pulling the trigger.
The setting has advanced technology, but that technology has pushed warfare back towards blades. It is a neat inversion and far more interesting than everyone firing differently coloured lasers across a corridor.
The Blades and Fighting Styles of Dune
The weapons in Dune are not direct copies of historical swords. Their designs combine practical knife forms, military aesthetics and the visual languages of their respective cultures.
| Weapon | Users | Characteristics |
|---|---|---|
| Atreides blades | Paul, Gurney, Duncan and Atreides troops | Functional military weapons suited to close, controlled attacks |
| Crysknife | The Fremen | A sacred blade made from the tooth of a sandworm |
| Sardaukar swords | Imperial Sardaukar | Severe, brutal weapons used with disciplined aggression |
| Harkonnen blades | Harkonnen troops | Utilitarian weapons matching the house’s industrial appearance |
| Gom jabbar | Bene Gesserit | A poisoned needle used to test Paul’s self-control |
Atreides weapons
House Atreides uses a mixture of long blades and fighting knives. The designs are restrained rather than decorative, reflecting a professional military culture. Duncan Idaho is especially effective with paired or rapidly exchanged blades, using changes of angle to exploit shield defences.
The weapons resemble long knives and short swords more than medieval European arming swords. They are built for confined fighting, rapid changes of direction and controlled penetration.
The crysknife
The crysknife is the most culturally significant blade in the film. Made from a sandworm’s tooth, it represents the relationship between the Fremen and the ecology of Arrakis.
When the housekeeper Shadout Mapes presents a crysknife to Lady Jessica, the exchange is not simply about identifying a weapon. Jessica’s knowledge of the blade convinces Mapes that she may fulfil part of a long-awaited prophecy.
Among the Fremen, drawing a crysknife carries obligations. The blade is more than equipment. It is a sacred object, a marker of belonging and an extension of the sandworm itself.
The gom jabbar
The gom jabbar is barely a blade, but it creates one of the film’s most intense confrontations. Reverend Mother Gaius Helen Mohiam holds the poisoned needle against Paul’s neck while he places his hand inside a box that produces unbearable pain.
The test asks whether Paul can master instinct through reason. An animal removes its hand and dies. A human remains still despite the agony.
It is a disturbing scene because Paul’s survival depends upon submitting to a woman who is entirely prepared to kill him. No armies, explosions or sandworms are required. Just a needle, a box and a teenager having the worst aptitude test imaginable.
How the Fight Choreography Works
The combat was designed to make the shield rules visible without turning every duel into a physics lesson. Blue flashes show when an attack has been stopped. Red indicates that a blade has passed through the shield.
Fight coordinator Roger Yuan developed the Atreides style with influences from Balintawak Eskrima, a Filipino martial art associated with close-range weapon work. This influence is particularly noticeable in the training scene between Paul and Gurney. The fighters use their free hands for checking, controlling and redirecting attacks while keeping their weapons close to the body.
Each military culture also fights differently.
- Atreides soldiers favour discipline, compact movement and mutual support.
- Sardaukar attack with speed, commitment and terrifying confidence.
- Fremen combat is economical, practical and adapted to survival without shields.
- Harkonnen troops rely more heavily upon aggression and overwhelming force.
The choreography is not always perfectly consistent about how slowly a blade must move through a shield. Absolute realism would probably make the fights look like two people reluctantly feeding knives through invisible jelly. The film wisely prioritises readability while preserving the central idea.
Paul and Gurney’s Training Fight
Paul’s training session with Gurney Halleck establishes several important points before the story reaches Arrakis.
Gurney believes Paul has become distracted and complacent. Paul, who would presumably prefer a normal breakfast, is ordered to fight. The exchange begins as practice but becomes increasingly serious as Gurney forces him to recognise the danger facing House Atreides.
Paul eventually gets a blade close enough to threaten Gurney, but Gurney has already positioned his own weapon against Paul.
The moment shows that Paul is talented without pretending he is unbeatable. It also introduces the film’s shield language and the controlled rhythm of its blade combat. Most importantly, it reveals that the Atreides family is preparing for war before its members fully understand where the attack will come from.
Duncan Idaho’s Last Stand
Duncan Idaho’s defence of Paul and Jessica is the film’s largest display of swordsmanship.
After surviving the Harkonnen attack, Duncan fights his way through Sardaukar soldiers and reaches an ecological station where Paul, Jessica and Liet Kynes have taken refuge. He seals the door behind him and confronts the attackers alone.
The fight works because Duncan never appears magically untouchable. He is faster and more experienced than his opponents, but each movement has effort behind it. He uses timing, momentum and the restricted space of the corridor to prevent the Sardaukar from fully surrounding him.
His apparent collapse, followed by one final attack, provides the scene with a properly heroic finish. It is dramatic, slightly excessive and completely earned. If a character is going to make a last stand, arriving late to his own death is a fairly memorable approach.
Paul’s Duel with Jamis
The duel with Jamis is smaller than Duncan’s last stand, but it carries much greater thematic weight.
After Paul and Jessica encounter Stilgar’s Fremen group, Jamis challenges Jessica’s right to remain with them. Paul becomes her champion and must fight Jamis without shields.
Paul hesitates because his training has conditioned him to fight shielded opponents. He repeatedly brings his blade close and pauses, expecting Jamis to yield. The Fremen interpret this as cruelty, believing Paul is playing with his opponent.
In reality, Paul has never killed anyone.
The duel ends with Paul fatally stabbing Jamis. It is not presented as a triumphant victory. Paul’s visions had shown Jamis as a friend and teacher, suggesting futures that will now never exist. Killing him closes one path while pushing Paul further towards another.
This is the real ending of Dune: Part One. Paul crosses into the Fremen world through violence, but the film refuses to treat the moment as a simple heroic awakening.
Is Paul Atreides Really a Chosen One?
The film deliberately uses the language of a chosen-one story while quietly undermining it.
Paul may possess extraordinary abilities, but the belief surrounding him has not arisen naturally. The Bene Gesserit have spent generations planting myths and prophecies across different cultures. These stories provide protection and influence for members of the order who may later need them.
Jessica recognises that the Fremen legends about a mother and son from another world have been shaped by this programme. Paul’s apparent fulfilment of prophecy is therefore partly the result of political and religious engineering.
That does not mean his powers are false. His visions are real, his Bene Gesserit training is effective and his exposure to spice strengthens his awareness. The uncomfortable question is whether Paul controls the prophecy or whether the prophecy has already begun controlling everyone around him.
The film presents him as both potential liberator and future tyrant. His visions of fanatical armies carrying the Atreides banner should make viewers suspicious of any straightforward messiah narrative.
The Politics Behind the Fall of House Atreides
The Emperor orders House Atreides to replace House Harkonnen as ruler of Arrakis. Publicly, this appears to be a prestigious appointment. In reality, the Emperor fears Duke Leto’s growing popularity among the noble houses.
Leto commands loyalty rather than merely demanding obedience. That makes him politically dangerous.
The Emperor secretly supports a Harkonnen assault by lending Baron Harkonnen several battalions of Sardaukar. These elite troops disguise themselves in Harkonnen uniforms, allowing the Emperor to deny involvement.
The plan succeeds because Dr Yueh disables the Atreides defences. His betrayal is driven by the Harkonnens’ capture and torture of his wife, although he also attempts to give Leto a chance to kill the Baron with a poison-gas tooth.
This is not a war between equal armies. It is a carefully managed extermination presented as a dispute between noble houses. The empire keeps its hands officially clean, which is usually how powerful institutions prefer their atrocities.
Arrakis, Spice and Colonial Power
Arrakis is treated as a resource colony. Its people, history and environment matter to the empire only because the planet produces spice.
House Harkonnen rules through violence and extraction. House Atreides offers a more respectful form of government, but Leto is still there to secure spice production for an imperial system. The difference between the two houses is morally significant, though neither has been invited by the Fremen.
Liet Kynes understands that Arrakis could one day become a greener world. The Fremen have spent generations collecting water and studying the desert, pursuing a project invisible to the empire.
Villeneuve gives these themes space without converting the film into a lecture. Massive harvesters, industrial aircraft and ranks of off-world soldiers are repeatedly contrasted with the Fremen’s careful adaptation to the desert. One group sees an ecosystem. The other sees an invoice.
How Dune Compares with Frank Herbert’s Novel
Villeneuve’s film is broadly faithful to the characters, politics and central themes of Herbert’s book, but it simplifies several elements.
Major changes include:
- The film covers only the first half of the novel.
- Political plotting and internal monologues are substantially reduced.
- Dr Yueh receives less development, making his betrayal feel more sudden.
- Thufir Hawat and Piter de Vries have smaller roles.
- Liet Kynes is portrayed by Sharon Duncan-Brewster, changing the character’s gender.
- Chani appears frequently through Paul’s visions but has limited direct involvement.
- Feyd-Rautha is held back for Dune: Part Two.
- The banquet scene in Arrakeen is omitted.
- The timescale around the Atreides takeover feels considerably shorter.
The loss of internal narration is the adaptation’s greatest challenge. Herbert regularly explains what characters are thinking, concealing and calculating. Villeneuve replaces much of this with glances, visual motifs and carefully controlled performances.
This creates a more cinematic story, though some secondary characters lose depth. Dr Yueh suffers most. His actions make sense, but the film gives viewers little time to understand the man before he dismantles an entire great house.
Cinematography and Production Design
Greig Fraser’s cinematography treats scale as a form of storytelling. Spaceships hang above cities like artificial weather systems. Human figures appear tiny beside fortresses, harvesters and sandworms.
The visual design gives each faction a recognisable identity.
| Faction | Visual style |
|---|---|
| House Atreides | Dark uniforms, sea mist, stone and restrained heraldry |
| House Harkonnen | Black surfaces, industrial forms and oppressive interiors |
| The Fremen | Practical desert clothing designed around water conservation |
| The Sardaukar | Pale armour, ritual imagery and severe military formations |
| The Bene Gesserit | Veils, layered robes and controlled ceremonial movement |
Caladan is wet, green and shadowed. Arrakis is exposed, bright and physically overwhelming. Giedi Prime appears cold and hostile even before Part Two expands its visual identity.
The scale occasionally makes the characters seem emotionally distant, but that distance is part of the film’s atmosphere. Everyone is trapped inside institutions much larger than themselves.
Hans Zimmer’s Score and the Sound of Arrakis
Hans Zimmer reportedly turned down the opportunity to score Christopher Nolan’s Tenet so he could work on Dune, having loved Herbert’s novel since childhood.
His score avoids the familiar language of heroic space opera. There are no cheerful brass themes announcing that adventure has arrived. Instead, Zimmer uses percussion, processed vocals, drones and unusual instrumental textures to make the setting feel ancient and alien.
The sound design is equally important. Ornithopters beat the air like mechanical insects. The Voice arrives as a forceful distortion of ordinary speech. Sandworms are heard through deep vibrations that suggest an animal too large for the human mind to measure comfortably.
At times the soundtrack becomes overwhelming, but subtlety was probably never going to survive an encounter with a 400-metre sandworm.
Where Dune: Part One Is Strongest
The film’s greatest achievement is making Herbert’s universe understandable without making it ordinary.
It succeeds through:
- Careful visual storytelling
- Distinctive faction and costume design
- A strong ensemble cast
- Thoughtful treatment of prophecy and political power
- Blade combat governed by clear fictional rules
- Exceptional sound, cinematography and production design
- A willingness to let scenes develop slowly
Rebecca Ferguson is particularly good as Lady Jessica. She combines fear, calculation and physical control in a performance that reminds us Bene Gesserit training involves rather more than speaking mysteriously from beneath a veil.
Oscar Isaac also makes Duke Leto deeply sympathetic without turning him into an uncomplicated saint. Leto knows he is walking into danger, but believes he can build something better. That combination of intelligence and doomed optimism gives the tragedy its weight.
Where the Film Struggles
Dune: Part One is deliberately paced, but deliberate can occasionally become extremely deliberate.
Several limitations stand out:
- The story ends before its major political and emotional arcs are resolved.
- Zendaya receives prominent marketing despite Chani having limited screen time.
- Some secondary characters feel underdeveloped.
- The Harkonnens are visually powerful but lack much of the novel’s political detail.
- Humour is scarce, leaving little relief from the solemn atmosphere.
- Exposition remains dense for viewers unfamiliar with the setting.
- Paul’s visions repeat frequently without always adding new information.
The film also asks the audience to invest in a sequel that had not yet been officially guaranteed when it was released. Viewed alone, it is an impressive but incomplete experience. Viewed beside Dune: Part Two, it works as the patient first movement of a much larger story.
Awards and Critical Legacy
Dune received ten Academy Award nominations and won six:
- Best Cinematography
- Best Film Editing
- Best Original Score
- Best Production Design
- Best Sound
- Best Visual Effects
It also won five BAFTA awards, including Cinematography, Original Score, Production Design, Sound and Special Visual Effects.
Its commercial and critical success allowed Villeneuve to complete his adaptation with Dune: Part Two in 2024. The first film now occupies an interesting place in modern science fiction. It proved that a major studio blockbuster could be slow, visually disciplined and politically complicated without abandoning spectacle.
It also introduced a generation of viewers to the phrase “desert power”, which sounds like an energy drink but is considerably more revolutionary.
Is Dune: Part One Worth Watching?
Yes, particularly if you enjoy large-scale science fiction, political drama or fictional worlds built around more than a collection of marketable vehicles.
The film requires patience. It does not hurry to explain every name, organisation or historical grievance. Much of its appeal comes from watching the pieces gradually connect.
Anyone seeking constant action may find the first hour slow. Those willing to settle into its rhythm will find one of the most carefully constructed science-fiction films of the modern era.
Watching Dune: Part One and Dune: Part Two together provides the most satisfying experience. The first film builds the world and destroys Paul’s old life. The second reveals what he chooses to build from the wreckage.
Final Verdict
Dune: Part One is an ambitious, unusually confident adaptation of a novel once considered nearly impossible to film. It simplifies Herbert’s story without stripping away its central concerns about empire, ecology, faith and manufactured heroes.
Its sword fights are more than visual decoration. The blades reveal how technology has shaped warfare, how cultures understand violence and how Paul changes after taking a life. Duncan Idaho’s final stand provides the heroic spectacle, while the duel with Jamis delivers the emotional consequence.
The film can be cold, slow and incomplete. It is also beautifully made, intellectually curious and far more unsettling than its chosen-one structure initially suggests. Beneath all the monumental architecture and sandworm business, Dune is asking a sharp question: what happens when people create a messiah and then discover they cannot control him?
That question gives the film its real edge.
Frequently Asked Questions
Why is the film called Dune: Part One?
The official theatrical title is Dune, although “Part One” appears in the opening title sequence. The film adapts roughly the first half of Frank Herbert’s original novel.
Why do soldiers use swords instead of guns?
Personal shields stop fast-moving projectiles but allow slower objects to pass through. Fighters therefore use controlled blade attacks to penetrate shield defences.
What is a crysknife made from?
A crysknife is made from the tooth of a sandworm. It is both a weapon and a sacred cultural object among the Fremen.
Who trained Paul Atreides?
Paul receives weapons training from Gurney Halleck and Duncan Idaho. Lady Jessica also teaches him Bene Gesserit disciplines, including precise control over his body and voice.
Does Dune: Part One tell the complete story?
No. It ends around the middle of Herbert’s novel. The adaptation continues in Dune: Part Two, released in 2024.
Is Dune suitable for younger viewers?
The film received a 12A classification in the UK. It contains combat, deaths, threatening scenes and some disturbing imagery, although the violence is generally less graphic than in many modern action films.
