With the 30th anniversary of the Harry Potter franchise less than a year-and-a-half away, there are about to be so many celebrations of “The Boy Who Lived,” including a hotly anticipated small-screen adaptation. That’s right, in the not-so-distant future, the Harry Potter TV show will take J.K. Rowling’s beloved novels and turn them into a years-long series.
To say that the world (that includes both wizards and muggles) is excited for the upcoming book-to-screen adaptation would be a major understatement at this point. The show, which will air on HBO and be available to stream for anyone with an HBO Max subscription, is shaping up to be one of, if not the biggest series in the works. If you want to know more about the show, its cast, and everything else that’s been announced so far, come along as we break down the Harry Potter TV show.
What Is The Harry Potter TV Show’s Premiere Date?
As much as we would love to go back to Hogwarts at some point on the 2026 TV schedule, that’s not going to be the case (though it was teased by Warner Bros. Discovery executives at one point). That said, the Harry Potter TV show is expected to hit the airwaves (and streaming world) at some point in 2027, per TVLine.
The Harry Potter TV Show Cast
In May 2025, Warner Bros. Discovery announced, following a casting call that saw nearly 32,000 young actors, that 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. Here’s everyone Warner Bros. Discovery has announced so far:
- 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

- 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

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 shoa is planned to be released over a decade, with each of J.K. Rowling’s seven books being adapted.
With the series turning each book into a season, 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. With production in full swing, maybe we’ll see some footage sooner rather than later.
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, who serves as an executive producer, had this to say about the massive project:
[HBO] 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.
The streamer 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 [HBO] Max Original series will dive deep into each of the iconic books that fans have continued to enjoy for all of these years.
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.” However, we still don’t know what that means, as no new movies have been announced.
Francesca Gardiner Is 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.
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.
A Second Season Is Already In The Works
While it’s no shocker that a second season of the Harry Potter TV show is happening, it is surprising that work has already gotten underway. In November 2025, HBO Chairman and CEO Casey Bloys (via Deadline) announced that the writers were already crafting the sophomore season throughout the production of the first installment:
The plan is to still try and get it — I don’t know if it’s going to be like stop shooting Season 1 on Friday and start Season 2 on Monday. There’ll be a break in there, but we’re going to do whatever we can to not have a huge gap. For the kids, obviously, but also for viewers. You know, trying to not have massive gaps. It is a big show, lots of special effects, obviously, massive operation, but we’re going to do what we can.
With a total of seven novels set to be adapted before this is all over and done with, it doesn’t seem likely that HBO will waste too much time between seasons. Now if every other big show could do something similar…
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!
