HBO’s Harry Potter Series Finds Its Harry, Ron and Hermione

HBO’s Harry Potter TV series has found its Harry, Ron and Hermione. The trio of Hogwarts freshmen are newcomers to Hollywood.

This time, Dominic McLaughlin will play Harry Potter, Arabella Stanton is Hermione Granger and Alastair Stout is the new Ron Weasley. In the films, those roles were played by Daniel Radcliffe, Emma Watson and Rupert Grint, respectively. There were eight Harry Potter films and a series of three Fantastic Beasts movies — a spinoff of the original IP. Author J.K. Rowling wrote seven Harry Potter books; the eighth book in the series was split into two movies.

“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,” showrunner and executive producer Francesca Gardiner and executive producer and director (of multiple episodes) Mark Mylod said 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.”

HBO very publicly hosted an open casting call to find this next installment’s new kids. Previously-announced cast can be found here.

The Harry Potter series, not (yet?) officially titled “Harry Potter,” to be clear, will be “a faithful adaptation of the beloved Harry Potter books,” HBO says. The series will stream on HBO Max (fka Max, ffka HBO Max — it’s a whole thing).

The HBO series is produced in association with Brontë Film and TV and Warner Bros. Television. It is executive produced by Rowling, Neil Blair and Ruth Kenley-Letts of Brontë Film and TV, and David Heyman of Heyday Films.

Harry Potter the series will begin production this summer for a 2026 rollout.
