The Harry Potter series reboot has officially found its golden trio.
HBO has announced the casting of screen newcomers Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley in its upcoming television adaptation of J.K. Rowling’s best-selling book series. The actors were selected following a widely publicised open casting call, which saw tens of thousands of children audition across the UK.
“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,” said showrunner and executive producer Francesca Gardiner and director/executive producer Mark Mylod in a joint statement. “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 trio will be stepping into roles made iconic by Daniel Radcliffe, Emma Watson and Rupert Grint in the original film series, which ran from 2001 to 2011 and remains a cultural staple.
A Faithful Return to the Wizarding World
The series is described by HBO as a “faithful adaptation” of Rowling’s novels, with each season set to cover one book from the seven-part saga. It’s expected to span over a decade, with the first season arriving in 2026 — nearly 30 years after the publication of Harry Potter and the Philosopher’s Stone.
While the new cast will bring a fresh face to Hogwarts, HBO has assured fans that the beloved original films will remain available to stream worldwide, alongside the new series on HBO Max (the streaming platform that had its name change from HBO Max to Max and, recently, back again).
The series is written and executive produced by Gardiner (Succession, His Dark Materials), who also serves as showrunner. Mylod, best known for directing episodes of Succession and Game of Thrones, will direct multiple episodes.
A Stacked Supporting Cast Builds the New Hogwarts
Beyond the newly revealed trio, HBO has also begun assembling a compelling lineup of established talent to bring the Wizarding World to life once more.
Six-time Emmy and two-time Tony Award winner John Lithgow has officially been cast as Albus Dumbledore, the wise and often enigmatic headmaster of Hogwarts. Lithgow takes over the role previously portrayed on screen by both Richard Harris and Michael Gambon.
Joining him is I May Destroy You star Paapa Essiedu as the complicated and beloved Severus Snape. Oscar nominee Janet McTeer is set to step into the robes of Professor Minerva McGonagall, while Shaun of the Dead and Hot Fuzz actor Nick Frost has been cast as the half-giant groundskeeper Rubeus Hagrid.
Other confirmed names include Rogue Agent’s Luke Thallon as Defence Against the Dark Arts professor Quirinus Quirrell and veteran British comedian Paul Whitehouse as the grumpy Hogwarts caretaker Argus Filch.
Casting details for other key characters — such as Draco Malfoy, Sirius Black, and Lord Voldemort — have not yet been revealed, but given the calibre of actors announced so far, HBO is clearly assembling a blend of rising stars and acclaimed veterans to flesh out this reimagined version of Rowling’s world.
J.K. Rowling’s Involvement
Despite the controversy surrounding her public statements in recent years, J.K. Rowling remains heavily involved as an executive producer. Her continued connection to the franchise has divided fans, especially after public disagreements with the original film’s stars. Nevertheless, HBO has remained firm in its decision to collaborate with Rowling, emphasising that her views will not shape the show’s content.
HBO is betting big on a long-term return to the world of magic, mystery, and mischief. Time will tell. As of now, the studio is eyeing a 2026 release.
