While it still feels like only yesterday when we were anticipating the arrival of each new Harry Potter book and movie, we’re now closing in on the countdown for a new adaptation of J.K. Rowling’s beloved Wizarding World 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. Naturally, we’re keeping tabs on everything that’s going on with the TV show, which is in production now.

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). We’ve known that 2027 was the targeted release year for Season 1 of the Harry Potter show, and thanks to an update by Deadline, we now know that it’ll be “early 2027.” This news was shared by Chairman and CEO of HBO and HBO Max content, Casey Bloys, in January 2026. No specific month was given, but at least we know we’re looking at – as of this update – about a year from now.

2027 is a good year to kick off a new adaptation, when taking into account that the very first book in the series, Harry Potter and the Philosopher’s Stone, was published in 1997, which will be thirty years ago next year.

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. Dominic McLaughlin is set to play Harry Potter, while Arabella Stanton and Alastair Stout have been picked to play Hermione Granger and Ron Weasley, respectively. The photo above gives us a glimpse of the trio, and if you want a tease of Arabella Stanton’s take on Hermione, you might want to check out Audible’s full-cast recordings of the audiobooks. Stanton voices the role of Hermione in the first three books.

The rest of the Harry Potter TV show cast is shaping up, including some juicy rumors. Here’s everyone Warner Bros. Discovery has announced so far:

What Is The Harry Potter TV Show About

When HBO announced the series, they noted that each of the books would be adapted throughout a decade-long series. Exactly how that all breaks down remains to be seen, as the books certainly vary in length.

The story begins with a young boy who learns he’s a wizard when he turns 11, and is invited to study witchcraft at Hogwarts. Over the course of seven books, Harry grows up alongside his best friends, Hermione and Ron, and each year they face bigger and more dangerous challenges, most focused on the rise of a dark wizard named Voldemort.

The story tackles a variety of themes, including growing up, facing grief, choosing between good and evil, and more, and it’s all set in a world where witches and wizards are living in secret among muggles (non-wizards).

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.

Hans Zimmer And Bleeding Fingers Will Compose A New Score For The Series

Speaking of the music, while fans are certainly familiar with John Williams’ score from the earlier movies, the series will feature a score from Hans Zimmer and Bleeding Fingers (a collective of composers, co-founded by Zimmer, along with Russell Emanuel and Steven Kofsky). HBO’s announcement included a quote from Zimmer, along with Kara Talve, and Anže Rozman, which includes this:

Magic is all around us, often just beyond reach, but as in the world of Harry Potter, you simply must look for it. With this score we hope to bring audiences that little bit closer to it whilst honoring what has come before.

As a fan of many of Hans Zimmer’s scores (Interstellar in particular, but there are so many great ones), I’m excited to hear what he and Bleeding Fingers bring to this show. But it’s also encouraging (and makes me a bit curious) to hear they want to honor what has come before. Will we hear notes of “Hedwig’s Theme” worked into the new score in some way? We’ll have to wait and see!

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.

An episodic approach may be just what the series needs in order to fully flesh out the story and characters J.K. Rowling created in her books. What’s more, I think it’s worth noting that, when the original films were coming out (particularly the earlier ones), the later books hadn’t been released yet. Each new installment in the book series was cloaked in secrecy until release, which I have to imagine made it a challenge when it came to adapting the films. Whereas, the writers of the TV show have a complete story to work with, which will hopefully allow them to develop the characters in a way that’s true to the source material.

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, more 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. Production is taking place at Warner Bros. Studios in Leavesden, UK.

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. If the story of the show is going to be true to the books, the main part will span about seven years, starting with Harry, Ron and Hermione in their first year at Hogwarts, and closing out during what would be their seventh year. We’ve certainly seen shows that feature teenagers who aren’t played by actual teenagers, but it’s likely they’ll want to keep the series moving before the young actors move too far into adulthood.

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!

With production in full swing for the first season, and a team of writers knocking out the second, we should be hearing a whole lot more about this enchanting series in the weeks and months (and years) to come.

Philip Sledge
Content Writer

Philip grew up in Louisiana (not New Orleans) before moving to St. Louis after graduating from Louisiana State University-Shreveport. When he's not writing about movies or television, Philip can be found being chased by his three kids, telling his dogs to stop barking at the mailman, or chatting about professional wrestling to his wife. Writing gigs with school newspapers, multiple daily newspapers, and other varied job experiences led him to this point where he actually gets to write about movies, shows, wrestling, and documentaries (which is a huge win in his eyes). If the stars properly align, he will talk about For Love Of The Game being the best baseball movie of all time.
