Harry Potter HBO Series Cast Revealed: Meet the New Harry, Hermione & Ron

Hogwarts has officially welcomed its next generation of witches and wizards: newcomer Dominic McLaughlin will wield the elder wand as Harry Potter, Arabella Stanton steps into Hermione Granger’s spellbinding shoes, and Alastair Stout completes the Golden Trio as Ron Weasley. A global open call that drew more than 30,000 audition tapes ended with casting directors Lucy Bevan and Emily Brockmann selecting the three British teens, praised by showrunner Francesca Gardiner and director-executive producer Mark Mylod for their “extraordinary chemistry and raw talent”. Cameras are set to roll this summer on the Warner Bros. Television production, positioned as a decade-long retelling that devotes one season to each of J.K. Rowling’s seven novels. Who else is headed to the Great Hall? • John Lithgow – Albus Dumbledore • Janet McTeer – Minerva McGonagall • Paapa Essiedu – Severus Snape • Nick Frost – Rubeus Hagrid • Luke Thallon – Professor Quirrell • Paul Whitehouse – Argus Filch Meet the new trio • Dominic McLaughlin (15) starred opposite Nick Frost in the upcoming Sky comedy “Grow,” earning rave notices for his comic timing. • Arabella Stanton (14) is fresh off a two-year West End run as Matilda Wormwood in “Matilda The Musical,” where critics praised her “fearless intellect”—an on-brand fit for Hermione. • Alastair Stout (15) makes his screen debut after leading roles with the National Youth Theatre, bringing what producers call “natural mischief” to Ron. Why a Harry Potter HBO series now? The wizarding franchise remains one of Max’s most-searched brands, and internal data shows appetite for a faithful, slow-burn adaptation that can dive into omitted subplots like S.P.E.W., the Marauders’ backstory and the Half-Blood Prince’s notebook. The series also gives Warner Bros. Discovery a long-term IP anchor as streaming competition intensifies. Release window and production details Principal photography begins in Leavesden Studios in July 2025, with Season 1 targeting a late-2026 premiere on Max in 4K HDR. Each instalment expects a budget north of $180 million, rivaling “House of the Dragon.” Behind the wand: key creatives • Francesca Gardiner (Succession, His Dark Materials) – showrunner, writer • Mark Mylod (Succession, Game of Thrones) – lead director • David Heyman – returning as executive producer, ensuring continuity with the film saga Rowling, Neil Blair and Ruth Kenley-Letts executive-produce via Brontë Film and TV, while Casey Bloys’ content team at HBO Max oversees. Fan reaction and social buzz Minutes after the reveal, #HarryPotterHBO trended worldwide on X, with Potterheads applauding the studio’s commitment to relative unknowns who “look the right age.” Others focused on the franchise’s renewed opportunity to spotlight under-explored characters like Peeves and the Hogwarts ghosts.
