‘Harry Potter’ HBO Series Casts Harry, Ron and Hermione
(WE) — HBO has officially unveiled the young trio set to portray Harry Potter, Hermione Granger, and Ron Weasley in its upcoming television adaptation of Harry Potter. After an international open casting call that drew more than 30,000 hopefuls, the network announced that Dominic McLaughlin will play Harry Potter, Arabella Stanton will take on the role of Hermione Granger, and Alastair Stout will step into Ron Weasley’s shoes.
HBO will begin filming this summer, with Dominic McLaughlin, Arabella Stanton, and Alastair Stout leading what the network calls a “faithful and decade-long adaptation” of J.K. Rowling‘s best-selling Harry Potter book series. The show promises to reintroduce the magical world of Hogwarts to a new generation.
Casting directors Lucy Bevan and Emily Brockmann led the extensive search. In a joint statement, Francesca Gardiner, the showrunner, and Mark Mylod, the executive producer and director, said they were thrilled to have chosen their Harry, Hermione, and Ron: “We are thrilled to announce we have found our Harry, Hermione, and Ron.” Their talent is extraordinary. We can’t wait for the world to witness their magic together on screen.”
They also extended gratitude to the thousands of children who auditioned, calling the search a pleasure and a testament to the abundance of emerging talent.
The three leads are mostly newcomers. McLaughlin recently appeared in Grow, a comedy on Sky that features Nick Frost and Golda Rosheuvel. Stanton starred as Matilda in Matilda: The Musical on London’s West End during the 2023–2024 run. For Stout, this marks his first major acting credit.
A seasoned cast of British and international stars will join the trio in HBO’s new Harry Potter series. John Lithgow, known for roles in The Crown and Conclave, will portray Albus Dumbledore. Janet McTeer, who appeared in Mission: Impossible – The Final Reckoning and The White Queen, will take on the role of Minerva McGonagall.
Paapa Essiedu, known for I May Destroy You and Gangs of London, has been cast as Severus Snape. Nick Frost will appear as the beloved half-giant Rubeus Hagrid. Luke Thallon, acclaimed for stage work in Leopoldstadt and Patriots, will play Quirinus Quirrell. Paul Whitehouse, a veteran of The Fast Show and Harry & Paul, will take on Argus Filch.
HBO is producing the series in collaboration with Warner Bros. Television and Brontë Film and TV, Rowling’s production company. Gardiner is writing the script and also serves as the showrunner. Mylod, who directed episodes of Succession, will direct several episodes and act as an executive producer.
J.K. Rowling, Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV will also executive produce. David Heyman, who produced the original film series through Heyday Films, returns to oversee the show’s production.

Rowling, the author behind the original seven Harry Potter books, has remained a polarizing figure in recent years. Her comments on gender identity have sparked backlash, particularly from LGBTQ+ communities. Some fans and actors from the film franchise have distanced themselves from her remarks.
When asked whether Rowling’s views influenced HBO’s decision-making, Casey Bloys, HBO’s Chief Content Officer, addressed the issue during an appearance on The Town podcast. “We already have a show on HBO from her called C.B. Strike that we do with the BBC,” Bloys said. “It’s pretty clear that those are her personal, political views. She’s entitled to them. Harry Potter is not secretly being infused with anything. And if you want to debate her, you can go on Twitter.”
The series has already drawn immense attention since its announcement. Warner Bros. Discovery CEO David Zaslav previously confirmed the studio’s commitment to a decade-long vision for the franchise. The adaptation will span all seven books, with each season reportedly dedicated to a single book. This approach offers a level of detail not possible in the original eight films.
While HBO has yet to announce an official premiere date, production is expected to span several years. The team hopes to launch the first season in either late 2026 or early 2027, depending on filming schedules and post-production timelines.
The announcement has sparked a flurry of speculation online. Fans have already begun theorizing about casting for other key characters like Sirius Black, Lord Voldemort, and Bellatrix Lestrange. Social media platforms, including Reddit, have been buzzing with wish lists and predictions.
Meanwhile, the original trio—Daniel Radcliffe, Emma Watson, and Rupert Grint—have all expressed mixed feelings about the reboot. While they’ve largely stepped away from the Wizarding World, their legacies remain tied to the original film adaptations released between 2001 and 2011.
Radcliffe recently told Entertainment Weekly he does not plan to return for a cameo but wishes the new cast success. “I think they’ll have the time of their lives,” he said. “It’s a huge journey, and I’m sure they’ll do it justice.”
The success of HBO’s adaptation will ultimately hinge on whether it can balance fan nostalgia with a fresh, modern approach. The involvement of talented newcomers, experienced directors, and high-profile producers suggests a project designed with longevity in mind.
With streaming platforms continuing to battle for dominance, franchises like Harry Potter provide valuable IP. For HBO, this series represents a strategic expansion of its fantasy portfolio following the success of Game of Thrones and its prequel House of the Dragon.
Expectations are high, but so is the excitement. For fans of the magical world, the countdown has officially begun.
