HBO’s Harry Potter TV series has found its Harry, Hermione Granger, and Ron Weasley. The trio will be played by acting newcomers: Dominic McLaughlin as Harry, Arabella Stanton as Hermione, and Alastair Stout as Ron.

“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 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.”

The young trio join John Lithgow as Albus Dumbledore, Paapa Essiedu as Severus Snape, Janet McTeer as Minerva McGonagall, and Nick Frost as Rubeus Hagrid. All four actors will be series regulars. Meanwhile, Luke Thallon was announced to play Quirinus Quirrell, and Paul Whitehouse to play Argus Filch, both in recurring roles.

It’s expected that each season of the series will adapt one of J.K. Rowling’s seven main entries in the Harry Potter series, which could mean a series franchise that spans many years.

The Harry Potter TV series will begin filming this summer for a 2026 debut. See the cast photo of the three young leads below:
