‘Harry Potter’ HBO Series Casts Harry, Ron and Hermione

Published: May 28 2025

HBO's television adaptation of "Harry Potter" has officially unveiled its trio of magical leads: Dominic McLaughlin will embody the iconic Harry Potter, Arabella Stanton will bring Hermione Granger to life, and Alastair Stout will step into the shoes of Ron Weasley. An incredible pool of over 30,000 aspiring actors competed for these pivotal roles since the open casting call was announced last autumn, setting the stage for an eagerly anticipated production that is slated to commence filming this summer.

"After an exhaustive and extraordinary search orchestrated by casting directors Lucy Bevan and Emily Brockmann, we are thrilled to unveil our Harry, Hermione, and Ron," proclaimed showrunner Francesca Gardiner and executive producer-director Mark Mylod in a joint statement. "The remarkable talent of these three exceptional actors is a sight to behold, and we eagerly await the moment the world witnesses their enchanting chemistry on screen. Our heartfelt gratitude extends to the tens of thousands of young hopefuls who auditioned; it has been an exhilarating journey to uncover such a wealth of fresh talent."

The original "Harry Potter" roles propelled Daniel Radcliffe, Emma Watson, and Rupert Grint to global fame in the early 2000s, and the HBO series holds the promise of doing the same for McLaughlin, Stanton, and Stout, who are relatively new to the spotlight. McLaughlin has previously starred in "Grow," a forthcoming comedy on Sky featuring Nick Frost and Golda Rosheuvel, while Stanton shone as Matilda in the West End production of "Matilda: The Musical" from 2023 to 2024. "Harry Potter" marks Stout's debut in a major role.

Joining this star-studded ensemble are John Lithgow ("Conclave," "The Crown") as Albus Dumbledore, Janet McTeer ("Mission: Impossible – The Final Reckoning," "The White Queen") as Minerva McGonagall, Paapa Essiedu ("I May Destroy You," "Gangs of London") as Severus Snape, Nick Frost ("Shaun of the Dead," "Hot Fuzz") as Rubeus Hagrid, Luke Thallon (Tom Stoppard's "Leopoldstadt," Rupert Goold's "Patriots") as Quirinus Quirrell, and Paul Whitehouse ("The Fast Show," "Harry & Paul") as Argus Filch.

Gardiner, who pens the series and serves as showrunner, also executive produces alongside Mylod, who will helm multiple episodes in collaboration with Brontë Film and TV and Warner Bros. Television. The series is also executive produced by author J.K. Rowling, Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV, as well as David Heyman of Heyday Films.

Rowling, the author behind the original "Harry Potter" books, has faced scrutiny in recent years due to her controversial stance on transgender issues. When asked if her views on the transgender community caused concerns for the show, HBO's chief content officer Casey Bloys recently stated on the "The Town" podcast: "We already have a show from her called 'C.B. Strike' that we co-produce with the BBC. It's clear that those are her personal, political views, and she is entitled to them. 'Harry Potter' is not being secretly influenced by any of that. If you wish to engage with her on these issues, Twitter is the platform for that."

Stanton is represented by Gavin Mills and Julie Gordon at Olivia Bell, and Public Eye.
