HBO's HARRY POTTER Series is Giving The Dursleys the Depth They Never Got in the Films
Everyone expected HBO's Harry Potter series to shake things up with expanded lore, character development, and deeper dives into the wizarding world. All of that's coming.
We'll get more of Dumbledore hunting Horcruxes, more time in classrooms with Harry, Ron, and Hermione, and a fuller look at life at No. 4, Privet Drive. But after watching the first trailer, the change that's actually got some fans people isn't magical at all. It's the Dursleys.
That might sound anticlimactic. These are, after all, the muggle relatives everyone loves to hate. In the books, J.K. Rowling wrote them as almost cartoonish villains, closer to the ugly stepsisters in Cinderella than fully realized human beings.
It was a conscious choice for a children's story; they existed to make Harry miserable so Hogwarts could feel like salvation. The films followed suit, leaning into the exaggeration for comedic effect. It worked, up to a point. But the further into the series both mediums went, the more the Dursleys struggled to hold up under scrutiny.
The HBO series is taking a different approach entirely.
The trailer spends a surprising amount of time at Privet Drive, and No. 4 looks nothing like the garish, overstuffed house from the films. It's grounded, recognizable, the kind of tidy, aspirational home you'd find in a 1990s British suburb.
That specificity matters. It tells you immediately that this show is interested in these people as actual human beings, not just obstacles between Harry and his destiny.
The standout moment is a quiet scene where Aunt Petunia cuts Harry's hair. That may seems like filler, but anyone who's read the books knows better. Harry's hair grows back overnight, an involuntary burst of magic he can't control and she can't contain.
The show plays it as something much darker than comic relief. Bel Powley's Petunia turns the scissors into something almost threatening, jabbing them toward Harry's face while telling him he's nothing special. It's unsettling in exactly the right way.
Powley plays Petunia not as a pantomime villain but as a woman wound tight with frustration and fear, someone who has convinced herself that suppressing Harry is somehow protection rather than cruelty. The scene works because it captures something the films never quite managed… Petunia's psychology. Her resentment isn't random. It has roots.
Amos Kitson's Dudley is another early highlight. We get an extended bullying sequence, Dudley chasing Harry through school corridors with his crew in tow, and it lands differently than the films' version of the character.
This Dudley feels insecure in a way that explains his behavior rather than just presenting it. That's a small distinction that makes a huge difference, especially knowing where Dudley ends up by the time the series reaches its later chapters.
This is the real advantage of adapting a completed story in a long-form format. The writers already know everything. They know why the Dursleys are the way they are, what shaped them, and how some of them will eventually change.
So instead of introducing Petunia and Vernon as one-note antagonists to be discarded once Harry reaches Hogwarts, they can build in the complexity from the very first episode. Every scene at Privet Drive can do double duty, telling you something about the present while quietly setting up the future.
High quality television has edge over film when it comes to this kind of slow-burn character work. A movie has to sprint. A series gets to breathe.
The Harry Potter films made the right call focusing on Hogwarts, the magic, and the spectacle; that's what those stories needed in that format. But the TV adaptation has room to do something different, and based on this trailer, it's using that room wisely.
