It was announced earlier this week that Dominic McLaughlin, Arabella Stanton and Alastair Stout will star as Harry, Hermione and Ron.
Warner Bros. Discovery first announced the project back in 2023, announcing that the TV series will be based on all seven books penned by J.K Rowling, with the first season set to adapt the first novel.

Harry Potter TV series release date speculation
The project had initially been pegged for a premiere in late 2026, but in November of this year, HBO boss Casey Bloys said that it was looking unlikely that they would meet that target, instead pushing the series into the following year (via THR).
The delay isn't necessarily anything to worry about, with Bloys telling Deadline in September: "Writers have started. [Director] Mark Mylod has started.
He added that the broadcaster hopes to produce subsequent seasons at a faster rate than typical visual effects-heavy shows, citing how quickly children can age on screen.
"From 11 to 13 is a big jump in kids lives," he said. "We are going to think about scheduling, so they don’t grow too much between seasons. Annual [release] will be tough, but it depends on how much is written at a time."
The author was absent from the 20-year anniversary special of the Harry Potter movies, while there were also boycotts of the Hogwarts Legacy game by some.
"JK Rowling has a right to express her personal views. We will remain focused on the development of the new series, which will only benefit from her involvement."
Who will star in the Harry Potter TV series?
Back in September, there was an open casting call looking for the three kids, with Warner boss Channing Dungey admitting it would be "tricky" to allocate the roles (via Variety).
Stout has been seen in TV advertisements, while McLaughlin will be seen in Sky Original comedy Grow.
"The talent of these three unique actors is wonderful to behold, and we cannot wait for the world to witness their magic together onscreen. We would like to thank all the tens of thousands of children who auditioned. It's been a real pleasure to discover the plethora of young talent out there."
Lithgow previously said of taking on the role: "It came as a total surprise to me. I just got the phone call up at the Sundance Film Festival for yet another film, and it was not an easy decision because it's going to define me for the last chapter of my life, I'm afraid. But I'm very excited."
While those four series regulars had previously been rumoured to be joining the project, some new additions are more unexpected.
Thallon is currently best known in the theatre world and most recently starred in the Royal Shakespeare Company's 2025 Hamlet.
Chatting to ComicBook.com, Radcliffe quashed any speculation about him making an appearance.
He said: "My understanding is that they’re trying to very much start fresh, and I'm sure whoever is making them will want to make their own mark on it and probably not want to have to figure out how to get old Harry to cameo in this somewhere."
Argus Filch star David Bradley told RadioTimes.com: "I think it’ll be very interesting to see what they will do with the extra time they’ll have to film more of the books than we could.
"Of course, you’ve got to sacrifice quite a lot of plot and characters. I’m assuming the reason they’re doing it is they’ll be able to include more of the story because they’ll have more screen time - a lot more than the films had. I’ll be interested. I haven’t had the call yet!"
Asked whether it felt strange to see a new adaptation in the works, Jason Isaacs, who played Lucius Malfoy, mused: "It’s no weirder for me than for everybody else who’s seen the films. I happen to be in the films too."
Behind the camera, we know that His Dark Materials writer Francesca Gardiner will serve as showrunner, while Succession director Mark Mylod is attached to produce and film some episodes.
"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," said Rowling.
What is the Harry Potter TV series about?
A statement from the newly branded Max explained: "The stories from each of Rowling’s Harry Potter books will become a decade-long series produced with the same epic craft, love and care this global franchise is known for.
It continued: "Each season will be authentic to the original books and bring Harry Potter and these incredible adventures to new audiences around the world, while the original, classic and beloved films will remain at the core of the franchise and available to watch globally."
