- The HBO ‘Harry Potter’ series has found its Harry, Ron and Hermione.
- Dominic McLaughlin, Arabella Stanton and Alastair Stout have the roles.
- John Lithgow is playing Dumbledore.
There is another chosen one.
A chosen three, actually, as now we know who will be following in the high-profile footsteps of Daniel Radcliffe, Emma Watson and Rupert Grint as Harry Potter, Hermione Granger and Ron Weasley in the ambitious new HBO series adapted from J.K. Rowling’s novels.
The new actors are Dominic McLaughlin, Arabella Stanton and Alastair Stout.
Here’s the statement from showrunner Francesca Gardiner and main director Mark Mylod about the new casting choices:
“After an extraordinary search led by casting directors Lucy Bevan and Emily Brockmann, we are delighted to announce we have found our Harry, Hermione, and Ron. 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.”
The process to find the Boy Who Lived and his two best friends has gone on for months and months, following a much-publicized open callout published by the show’s casting director Bevan, which asked for children aged between nine and 11 as of April 2025 who were residents of the UK and Ireland.
The three are mostly newcomers, though McLaughlin has a role in the BBC’s upcoming action adventure series ‘Gifted’ while Stanton played Matilda in ‘Matilda The Musical’ in London’s West End across several months.

What’s the story of the ‘Harry Potter’ TV series?

Here’s the official HBO statement on the show:
“The series will be a faithful adaptation of the beloved ‘Harry Potter’ book series by author and executive producer J.K. Rowling. It will feature a new cast to lead a new generation of fandom, full of the fantastic detail and much-loved characters ‘Harry Potter’ fans have loved for over twenty-five years. Each season will bring ‘Harry Potter’ and these incredible adventures to new audiences around the world, while the original, classic and cherished films will remain at the core of the franchise and available to watch globally.”
Gardiner scored the job of showrunner after HBO conducted an extensive search for the right writer/producer. Mylod will direct multiple episodes of the series, having worked on the likes of ‘Succession’ and ‘Game of Thrones.’
The show will be shot at Warner Bros.’ Leavesden Studios facility outside London in the UK, where the movies were made.
Who else has been cast in the ‘Harry Potter’ series?

Previously, we learned that John Lithgow would be Albus Dumbledore, alongside Janet McTeer (Professor Minerva McGonagall), Paapa Essiedu (as Severus Snape) and Nick Frost (bringing gamekeeper Rubeus Hagrid to screens), and they’ll make up part of the series regular cohort alongside the young newcomers.
In addition, Luke Thallon (whose main screen credit so far has been a tiny role in 2018’s ‘The Favourite’) and UK comedian and actor Paul Whitehouse (who US audiences might know from ‘The Death of Stalin’ but also has ‘Potter’ form after playing Sir Cadogan in third movie ‘The Prisoner of Azkaban’) are recurring guest stars.
Thallon has nabbed the role of Professor Quirinus Quirrell, a key part of ‘Harry Potter and the Philosopher’s Stone,’ while Whitehouse is set to play Hogwarts caretaker and grumpy cat owner Argus Filch, who pops up throughout the stories.
What about the J.K. Rowling issue?

‘Potter’ creator and original novelist J.K. Rowling is a big consideration here, since A) she has final say on anything adapted from the books and B) is a problematic figure given her negative views on trans people.
This was HBO’s recent statement on the issue:
“Warner Bros. has been working with J.K. Rowling and in the ‘Harry Potter’ business for over 20 years. Her contribution has been invaluable. We are proud to once again tell the story of ‘Harry Potter’ — the heartwarming books that speak to power of friendship, resolve and acceptance. J.K. 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.”
Fiennes (yes, him again) weighed in on the issue when talking to The New York Times in 2022:
“J.K. Rowling has written these great books about empowerment, about young children finding themselves as human beings. It’s about how you become a better, stronger, more morally centered human being. The verbal abuse directed at her is disgusting, it’s appalling. I mean, I can understand a viewpoint that might be angry at what she says about women. But it’s not some obscene, über-right-wing fascist. It’s just a woman saying, ‘I’m a woman and I feel I’m a woman and I want to be able to say that I’m a woman.’ And I understand where she’s coming from. Even though I’m not a woman.”
When will the ‘Harry Potter’ series be on screens?
HBO CEO Casey Bloys recently said that he expects the show to debut in late 2026 or early 2027, which makes sense given that production isn’t likely to start until later this year.
