Dune is heading into its darkest chapter yet. The first trailer for Dune: Part Three is finally here, giving fans a first look at how Denis Villeneuve plans to end his sci-fi trilogy. Based on Frank Herbert’s Dune Messiah, the film moves the story away from Paul’s rise to power and focuses on the consequences of what he has achieved. The trailer is full of stunning visuals, emotional moments and some big surprises. Here’s everything the trailer reveals.
A dark chapter begins
Dune: Part Three takes place approximately two decades after Paul Atreides (Timothée Chalamet) claims the throne at the end of Dune: Part Two. Now Emperor, he has achieved everything he ever dreamed of, but at an unimaginable cost. A brutal holy war has been waged across the galaxy in his name, and the weight of those choices is finally weighing on him.
As old allies return and powerful new enemies emerge, Paul becomes embroiled in a dangerous conspiracy that threatens both his empire and his future. Tormented by disturbing visions and the unexpected return of someone she believed was gone forever, she must also confront a growing rift with Chani (Zendaya). Chani has never accepted Paul’s decision to claim the throne, and the trailer makes it clear that the hurt between them hasn’t diminished over time. As the rebellion grows and danger approaches, Paul is forced to decide what he is willing to sacrifice to protect those he loves.
Duncan returns to Idaho in surprising fashion
One of the biggest surprises in the trailer is the return of Jason Momoa as Duncan Idaho, even though the warrior died in Dune: Part One. The trailer begins with Duncan’s voiceover describing the horrors that occurred under Paul’s empire. Fans will remember that Duncan sacrificed himself while fighting the Emperor’s Sardaukar soldiers to help Paul escape. So when the trailer later shows him kneeling before Paul in the Atreides throne room, the obvious question is: How is Duncan back?
The answer lies in the fascinating lore of Dune. This is not the original Duncan, but Hayet, a “ghoul” created by the secretive Tleilaxu using cells from Duncan’s dead body. His metallic looking eyes immediately indicate that there is something different about him. Although his return may seem emotional at first, Het has actually been sent to Paul as a “gift” by his enemies. His true purpose is far more dangerous, as he aims to destabilize Paul and become part of a larger conspiracy against the Emperor.
Paul’s enemies united against him
Paul Atreides won’t fight just one enemy. Instead, some of the most powerful forces in the universe have quietly come together to destroy his empire. Among them is Princess Irulan (Florence Pugh), Paul’s wife in name only. She is still loyal to her family’s legacy and hopes to play a key role in the Bene Gesserit’s plans by trying to birth an heir to Paul.
Meanwhile, Reverend Mother Gaius Helen Mohiam (Charlotte Rampling) continues to lead the Bene Gesserit’s efforts to regain control after Paul’s rise to power, disrupting the breeding program they spent generations building. The trailer also offers a first look at the impressively spaced guild via guild navigator Adric. Her ability to see the future allows the group to hide their plans from Paul’s own view, giving the plot a major advantage.
Another major player is Scytale (Robert Pattinson), Tleilaxu’s shape-shifting face dancer. He is a man whose loyalties are unclear, making him one of the most dangerous and unpredictable individuals in the story.
The next generation of House Atreides
The trailer also offers a glimpse into the future of House Atreides. In one of the emotional moments, Paul and Chani talk about what they will name their baby in memory of Paul’s father, Ghanima if it’s a girl and Leto if it’s a boy. It’s a brief conversation, but it means a lot to fans of Frank Herbert’s novels, as these children play a vital role in the larger Dune story. The characters will be portrayed by newcomers Ida Brooke and Nakoa-Wolf Momoa, the son of Jason Momoa.
Beginning of Deadly Stone Burner
One of the biggest moments in the trailer is the first glimpse of the Stone Burner, a banned weapon with destruction on the scale of a nuclear bomb. It is one of the most dangerous weapons in the Dune universe and plays a major role in the story.
Stone burners also emit intense radiation that can blind people. The trailer appears to be teasing exactly that, showing Paul walking alone in Arrakeen at night after losing his eyesight.
Alia has become a powerful leader
After appearing only briefly at the end of Dune: Part Two, Anya Taylor-Joy’s Aliya Atreides has a much bigger presence this time around. The trailer shows Aliya has grown up and is playing an important role in Paul’s empire. She is seen leading prayers and standing by her brother as one of his most trusted individuals. This is one of the film’s most obvious signs of a time jump, showing how much the world and its characters have changed since the previous film.
