Meet the new generation of wizards: Harry, Ron and Hermione cast announced for long-awaited Harry Potter series

HBO has officially announced the names of the three young actors who will play Harry Potter, Hermione Granger, and Ron Weasley in the upcoming television series based on J.K. Rowling’s novels. Dominic McLaughlin will take on the role of Harry Potter, Arabella Stanton will play Hermione Granger, and Alastair Stout has been cast as Ron Weasley.

Selected after months of open casting

The announcement comes eight months after HBO launched an open casting call for the central trio. Casting directors Lucy Bevan and Emily Brockmann led the process, which invited children from the UK or Ireland aged between 9 and 11, as of April 2025, to audition. In a statement, showrunner Francesca Gardiner and director Mark Mylod said, “After an extraordinary search… we are delighted to announce we have found our Harry, Hermione, and Ron. The talent of these three unique actors is wonderful to behold.” They also thanked the “tens of thousands” of children who auditioned.

The casting call also emphasized HBO’s commitment to “inclusive, diverse casting” and encouraged applications from all backgrounds, without bias related to ethnicity, gender, disability, or other protected categories.

Carrying forward iconic roles

The new cast members inherit their characters from Daniel Radcliffe, Emma Watson, and Rupert Grint, who played the trio in all eight Harry Potter films. The upcoming series is described as a “faithful adaptation” of the books, with plans to explore each of the seven novels in greater detail.

Though HBO hasn’t confirmed the total number of seasons, the show aims to delve deeply into the original texts. Francesca Gardiner, known for her work on His Dark Materials, will serve as the writer, executive producer, and showrunner. Mark Mylod, known for directing episodes of Succession and Game of Thrones, will direct multiple episodes and serve as an executive producer. J.K. Rowling will also be on board as an executive producer.

Additional cast and production timeline

Several other roles have also been announced. John Lithgow will play Albus Dumbledore, while Janet McTeer takes on the role of Professor McGonagall. Paapa Essiedu will appear as Professor Snape, and Nick Frost has been cast as Rubeus Hagrid. Paul Whitehouse will play Argus Filch, and Luke Thallon has been cast as Professor Quirrell.

Production for the series is scheduled to begin this summer.
