Welcome back to Arrakis, all ye bookworms and mentats! We are here to compare the book and the 2021 movie. Before we begin, it's important to remember that the movie was only part one! So remember that only around half the book is currently in movie form (roll on the next movie!!!).

I have to admit, I love this movie with the red hot fiery passion of ten thousand suns!! So le'ts get on to it.

THE PLOT:

In the distant future, Duke Leto Atreides, ruler of the planet Caladan, is assigned by the Padishah Emperor Shaddam IV to replace Baron Vladimir Harkonnen as the fiefholder of Arrakis, a harsh desert planet and sole source of "spice", a valuable psychotropic substance that imparts heightened vitality and awareness. Spice is key to interstellar travel, giving Spacing Guild Navigators the ability to guide starships to traverse space instantaneously and safely. Shaddam plots for House Harkonnen to retake Arrakis, secretly aided by his Sardaukar troops, to destroy House Atreides. Leto is suspicious of the Emperor but weighs the risks against the power of controlling Arrakis and making an alliance with its mysterious natives, the Fremen.
Leto's concubine, Lady Jessica, is an acolyte of the Bene Gesserit, an exclusive sisterhood whose members possess advanced physical and mental abilities. As part of their centuries-long breeding program, they instructed her to bear a daughter whose son would become the Kwisatz Haderach, a Bene Gesserit and messianic superbeing with the clairvoyance necessary to guide humanity to a better future. She disobeyed, and bore a son, Paul. Paul is trained by Leto's aides, Duncan Idaho, Gurney Halleck, the Suk doctor Wellington Yueh, and the Mentat Thufir Hawat, while Jessica teaches him Bene Gesserit disciplines. Paul confides in Jessica and Duncan that he is troubled by visions of the future. In response to Paul's increasing prescience, the Reverend Mother and Imperial Truthsayer Gaius Helen Mohiam visits Caladan and subjects him to a death-alternative Gom jabbar test to assess his humanity and impulse control, which he passes. At a secret meeting on Giedi Prime, Mohiam insists that Baron Harkonnen spare Paul and Jessica during his planned coup, to which he duplicitously agrees.
House Atreides arrives at Arrakeen, the fortress stronghold on Arrakis. Duncan's advance party has made contact with the Fremen. The natives revere Paul and Jessica, which Jessica explains is due to the Bene Gesserit sowing beliefs on Arrakis centuries earlier. Leto negotiates with Fremen chieftain, Stilgar, and meets the Imperial Judge of the Change, Dr. Kynes, a planetologist who lives among the Fremen. Kynes briefs them on the dangers of spice harvesting, and the giant sandworms which travel under the desert and make the use of protective Holtzman shields unwise. During a flight, they dramatically rescue a stranded spice-harvesting crew from a sandworm; Paul's exposure to the spice triggers intense premonitions.
An attempt to assassinate Paul with a hunter-seeker fails. Yueh betrays the Atreides and disables Arrakeen's shields, allowing the Harkonnens and Sardaukar to invade. He incapacitates Leto, planning to exchange him for his wife, who is the Baron's prisoner. Yueh replaces one of Leto's teeth with a poison gas capsule with which the Duke can assassinate the Baron. Leto releases the gas, killing himself and the Baron's Mentat, Piter De Vries, but the Baron survives. Though the Baron has arranged to have Paul and Jessica dropped deep in the desert to die, a compassionate Yueh has left them with stillsuits and other survival supplies. Jessica uses a Bene Gesserit technique called "the Voice" to overpower and kill their captors. Paul and Jessica journey overnight in the desert where Paul, surrounded by spice, has visions of a bloody "holy war" fought across the universe in his name.
Baron Harkonnen gives command of Arrakis to his nephew, Rabban, and orders him to restart spice production to recoup the cost of the invasion. Paul and Jessica are found by Duncan and Kynes, and Paul discloses his plan to marry one of Shaddam's daughters to avert the civil war that would ensue from news of the Emperor's treachery. They are found by the Sardaukar, and Duncan sacrifices himself to allow Paul and Jessica to escape. Kynes is mortally wounded by Sardaukar but summons a sandworm that devours them. In the deep desert, Paul and Jessica encounter Stilgar's tribe, including Chani, the girl in Paul's visions. Fremen warrior Jamis opposes Stilgar's lenience to them and challenges Paul to a ritual duel to the death, which Paul wins. Against Jessica's wishes, Paul joins the Fremen to fulfill his father's goal of bringing peace to Arrakis.
