For the better part of the past 30 years, the Harry Potter franchise has been one of the biggest brands in pop culture, and now there’s a Harry Potter TV show on the way. Following seven critically acclaimed and wildly popular novels and the Harry Potter movies that followed in the early 21st century, the small-screen version is a long time coming.
First announced back in 2023, the long-in-the-works upcoming book-to-screen adaptation is closer than ever to coming to HBO and an HBO Max subscription, and we have all sorts of information about the highly anticipated project. From the young actors who’ll play Harry, Hermione, and Ron to a release window and everything in between, there’s a lot to break down on this ambitious take on J.K. Rowling’s beloved wizarding novels.
What Is The Harry Potter TV Show’s Premiere Date?
An exact Harry Potter TV show premiere date has not yet been announced, but it sounds like it will hit the airwaves (and one of the best streaming services) at some point in 2027, HBO has announced. This comes after comments from Warner Bros. executives who teased a 2026 debut for the upcoming series.
The Harry Potter TV Show Cast
In May 2025, Warner Bros. Discovery announced that, following a casting call that saw nearly 32,000 young actors, the three main roles in the upcoming series had been filled. Domnicic McLaughlin is set to play Harry Potter while Arabella Stanton and Alastair Stout have been picked to play Hermione Granger and Ron Weasley, respectively. But they’re not alone as the rest of the Harry Potter TV show cast is shaping up:
- John Lithgow as Albus Dumbledore
- Janet McTeer as Minerva McGonagall
- Paapa Essiedu as Severus Snape
- Nick Frost as Rubeus Hagrid
- Luke Thallon as Quirinus Quirrell
- Johnny Flynn as Lucious Malfoy
- Paul Whitehouse as Argus Filch
- Lox Pratt as Draco Malfoy
- Daniel Rigby as Vernon Dursley
- Bel Powley as Petuna Dursley
- Katherine Parkinson as Molly Weasley
- Alessia Leoni as Parvati Patil
- Leo Earley as Seamus Finnigan
- Bertie Carvel as Cornelius Fudge
- Rory Wilmot as Neville Longbottom
- Amos Kitson as Dudley Dursley
- Louise Brealey as Madam Rolanda Hooch
- Anton Lesser as Garrick Ollivander
What Is The Harry Potter TV Show About
Another point of interest when it comes to the Harry Potter TV series is that the HBO series is planned to be released over a decade, with each of J.K. Rowling’s seven books being adapted. While we don’t yet know how the series will be broken up just yet, we can expect to watch Harry go from being a young boy orphaned after the death of his parents at the hand of Lord Voldemort to a new student at Hogwarts School of Witchcraft and Wizardry to the hero of the Wizarding World by the time it’s all done.
The Harry Potter Teaser
When Warner Bros. Discovery announced the Harry Potter TV show back in 2023, the company’s various social channels, like its official Twitter account, released a brief teaser trailer welcoming everyone to Hogwarts:
As you probably noticed by now, the teaser doesn’t offer any major details about the show, its cast, or how it will adapt the beloved fantasy books into a TV show, but the Great Hall’s floating candles and John Williams’ iconic score are more than enough to hold us over for now.
The Harry Potter TV Show Will Be A ‘Faithful’ Adaptation Of J.K. Rowling’s Book Series
Though the Harry Potter movies did a tremendous job of bringing J.K. Rowling’s books to life on the big screen, there was a lot that was left out in the adaptations, most likely due to the length of the later novels. Well, that hopefully won't be a problem with the Harry Potter series as the TV format allows for a “faithful adaptation” of the source material, as Warner Bros. Discovery has announced. Following the big announcement, Rowling had this to say about the massive project:
Max’s commitment to preserving the integrity of my books is important to me, and I'm looking forward to being part of this new adaptation which will allow for a degree of depth and detail only afforded by a long form television series.
Max has also announced that the new show will be “authentic to the original books” and will bring the popular property to new audiences around the world, as Casey Bloys, Chairman and CEO, HBO & HBO Max Content put it:
We are delighted to give audiences the opportunity to discover Hogwarts in a whole new way. Harry Potter is a cultural phenomenon and it is clear there is such an enduring love and thirst for the Wizarding World. In partnership with Warner Bros. Television and J.K. Rowling, this new Max Original series will dive deep into each of the iconic books that fans have continued to enjoy for all of these years.
But this doesn’t mean that the eight Harry Potter movies will be yesterday’s news, as Warner Bros. holds the films “at the core of the franchise.”
Succession’s Francesca Gardiner Will Be The Harry Potter Showrunner
In June 2024, THR reported that Succession’s Francesca Gardiner had been announced as the series’ showrunner. But Gardiner won’t be alone with the daunting task of turning seven iconic novels into a TV series, as Mark Mylod will also be working on the creative team and directing multiple episodes, though an exact number has not yet been determined. Mylod, who previously directed an episode of Game of Thrones, most recently helmed a powerful episode of The Last of Us Season 2, which could be a taste of what’s to come for some of the more intense and heartbreaking moments in the Harry Potter franchise.
J.K. Rowling Will Serve As An Executive Producer For The Harry Potter Series
Though J.K. Rowling won’t be writing the Harry Potter TV series, the author responsible for the landmark fantasy franchise will be serving as an executive producer. We don’t yet know how much Rowling will be involved with the day-to-day of the series, but she is expected to be involved with the decision-making process throughout its development and production.
This won’t be the first time Rowling has had a say in an adaptation of her popular book series, as she helped Steve Kloves when the screenwriter was working on the scripts for the various Harry Potter movies. She later received producer credits for the final two entries in the series as well as the three Fantastic Beasts movies, which she also wrote.
Production On The Harry Potter TV Series Kicked Off In July 2025
Though there’s still some time before the fall semester kicks off for us in the real world, school is officially in session at Hogwarts, as production is officially underway on the Harry Potter TV series. In July 2025, Warner Bros. announced that cameras were rolling on the series by sharing a pic of Dominic McLaughlin dressed up as “The Boy Who Lived.” We don’t know how long the production will last, but with the show set to debut in 2027, it will probably be a lengthy shoot.
The Harry Potter Series Will Explore Hogwarts Like Never Before
The Harry Potter movies spent a great deal of time in and around Hogwarts, but there was a lot that was forced to be left off the page due to time constraints. Well, that shouldn’t be a problem for the upcoming series, considering it’s going to have so much time to adapt the books. And that’s something executive producers Mark Mylod and Francesca Gardiner told the Harry Potter official website back in 2024. When speaking with the site, Mylod said:
We went with the idea that Hogwarts is a real place. So there will be elements of Georgian architecture, attempts at naturalism. Because, of course, we have the luxury of long-form storytelling.
Gardiner was quick to point out that they will simply have a larger “sandpit” with the series.
We’re both massively fond of the movies, they’re amazing, what an amazing feat of creative pursuits. We get a bigger sandpit to play in.
But it isn’t just architecture and an expanded castle that the show’s producers are excited to pursue with the new show, as they revealed during the panel that audiences will get to have some with Peeves, one of the most prominent ghosts in the halls of Hogwarts.
How To Watch The Harry Potter Movies
Considering we’re still a couple of years away from the Harry Potter TV show’s debut, there’s plenty of time to go back and watch the original eight movies. If you want to watch all the Harry Potter movies in order (at least those about “The Boy Who Lived”), now’s your golden opportunity, because they’re all streaming on Max at this moment (they are also available for anyone with a Peacock subscription).
But again, there’s still plenty of time, so don’t feel like you have to rush through all seven years of Harry’s education and adventures and battles at Hogwarts!
