7 Harry Potter Changes From the Books the HBO Reboot Must Make

Fans are really looking forward to the new Harry Potter series on HBO because it will have the space to include much more detail from the books that the movies left out. While the eight films generally followed J.K. Rowling’s story, they also made changes and simplified things. They removed political themes, complex character traits, and several storylines. The HBO series, with each season covering one book, has the opportunity to address these issues – like Hermione often just explaining things for the audience, the portrayal of Dumbledore, and the limited role of the Ministry of Magic.

Early reports about the new HBO Harry Potter series suggest it will closely follow the books, though some casting choices will be different. The show, which is expected to premiere in December 2026, is also hinting at including characters like Peeves, showing a dedication to the original source material. This series has the potential to become the defining Harry Potter experience for a new generation.

7) Show the Full First Wizarding War in Flashback

From 1970 to 1981, the wizarding world was gripped by the First Wizarding War, a terrifying period marked by secret attacks, spying, torture, and widespread killings of both magical people and Muggles. Voldemort’s Death Eaters were far more numerous than the Order of the Phoenix, and the war demonstrated just how dangerous things became when he was in power. The films only hinted at the true horror of this time, most notably in the Pensieve sequence featuring Barty Crouch Jr. in Goblet of Fire.

The episode barely touched on the war’s devastation, instead focusing solely on Karkaroff revealing Death Eaters. Considering the Marauders fought in the war and experienced loss, showing these experiences through flashbacks could help fans connect with James Potter, Sirius Black, and Remus Lupin. Spreading flashbacks throughout the series could powerfully illustrate the urgency of stopping Voldemort.

6) Make the Horcrux Hunt Feel Psychologically Deadly

In the books, the Horcrux locket wasn’t just a magical object—it attacked people’s minds, bringing out their deepest fears and weaknesses. It highlighted Ron’s feelings of inadequacy, Harry’s tendency to suspect the worst, and Hermione’s moments of hopelessness. The movies did a good job of showing this through the characters’ behavior and the strain it put on their friendship. However, the films presented these fears as isolated incidents rather than a continuous, underlying effect.

The upcoming HBO reboot of Harry Potter should dedicate time to properly portraying the emotional impact of the Horcrux on Ron Weasley. The books showed a gradual, months-long psychological breakdown, which was far more complex than the single argument depicted in the films. The Horcrux’s effects were also much more damaging and difficult to overcome in the books, and the series should reflect that. To be truly effective, the reboot needs to showcase how horrific the Horcruxes were and fully explore the psychological toll they took on the characters.

5) Give Neville Longbottom His Proper Arc

Fans of the Harry Potter series often wondered if Neville Longbottom might actually be the ‘Chosen One’ instead of Harry. The books cleverly led readers to believe this, making Neville a compelling character. However, the films never explored this possibility. While Neville did bravely confront Voldemort in the final movie, it felt a bit out of the blue and didn’t quite connect to the hints in the books.

The upcoming HBO reboot of Harry Potter has a chance to improve on the original story. Both Harry and Neville Longbottom could have realistically been the ‘Chosen One,’ and it would have been a compelling twist if Voldemort targeted Harry simply because he thought Harry was the more promising candidate. The series should also show Neville visiting his parents, who were long-term patients in an institution due to the trauma they endured. Furthermore, Neville deserves a more prominent role, especially highlighting his rebuilding of Dumbledore’s Army and his crucial act of killing Nagini during the Battle of Hogwarts.

4) Restore the Ministry of Magic as a Functioning Antagonist

As a huge Harry Potter fan, one thing that really struck me in Order of the Phoenix was how intensely the Ministry of Magic tried to discredit Dumbledore – and poor Harry! The books really showed the full extent of this long, nasty campaign, with the Daily Prophet constantly spreading lies. The movies touched on it, sure, but it felt really watered down. They just didn’t capture how relentless and damaging it was like the book did.

The movie adaptations significantly cut Percy Weasley’s story, and with it, much of the books’ political themes. In the novels, Percy’s initial loyalty to the Ministry, against his family’s beliefs, and his later realization of the Ministry’s flaws made his eventual return to his family during the Battle of Hogwarts particularly meaningful. His storyline also highlighted why Dolores Umbridge was given so much authority. Showing the Ministry at its most powerful in the upcoming HBO series will make its downfall in Deathly Hallows even more impactful.

3) Restore the Hufflepuff and Ravenclaw Characters

As a fan, I always felt like the movies really favored Gryffindor and Slytherin. It seemed like everything revolved around Harry, Ron, Hermione, and Draco. It was especially disappointing to me that they didn’t include any named Hufflepuff students in things like Dumbledore’s Army – the books had great characters like Susan Bones and Zacharias Smith, but they were just left out of the films.

The story also missed opportunities with characters like Ernie Macmillan. His initial accusation that Harry Potter was the heir of Slytherin in Chamber of Secrets could have led to a powerful moment of redemption when he publicly defended Harry in Half-Blood Prince, but that potential was lost. Luna Lovegood is the only Ravenclaw character who receives significant development in the films, and even her story is more detailed in the books. Similarly, Cedric Diggory is the only Hufflepuff who gets much screen time, and unfortunately, his character is killed off.

2) Let Dumbledore Be Morally Complicated From the Start

The Fantastic Beasts films explored Albus Dumbledore’s past in more detail, revealing that at age 17, he and Gellert Grindelwald co-authored a controversial philosophy called For the Greater Good. This ideology promoted the idea that wizards should rule over non-magical people. Dumbledore initially believed in these dangerous ideas, but eventually changed his stance after Grindelwald unleashed years of violence and oppression. For a significant period, however, Dumbledore genuinely supported these harmful beliefs.

The movies really softened up Dumbledore in the Harry Potter world, which was disappointing because he was really manipulating Harry for his entire life. He deliberately withheld information from Harry for years and trained him to ensure that Harry would die if need be. Snape even said Dumbledore raised Harry to be a “pig for slaughter,” and HBO needs to plant the seeds and show these contradictions to make Dumbledore more complicated than he was in the films.

1) Give Hermione More Than Exposition

It’s surprising how much dialogue originally spoken by Ron Weasley in the Harry Potter books was actually given to Hermione in the movies. For example, Hermione delivers the line, “If you want to kill Harry, you’ll have to kill us too,” which was Ron’s line in the books. There’s also a scene where Ron, in a panic, asks Hermione, “Are you a witch or not?” when trying to escape the Devil’s Snare – a line she says in the books. While Hermione makes mistakes in the novels, the movies portray her as always being correct.

The upcoming Harry Potter HBO series has a chance to improve Hermione’s character by giving her weaknesses and allowing her to grow. In the books, she wasn’t perfect, and that struggle made her a more compelling character. Removing those flaws, and even storylines like her fight for house-elf rights, turned her into simply a device for explaining things, rather than a fully realized member of the central trio. Giving the new Hermione some imperfections will make her a more powerful and interesting character.
