In an interview with Deadline, Bloys said the network has been saying 2027 for some time, and that the show is expected in early 2027, though he stopped short of pinpointing a specific month. He clarified that while the range might include January through April, HBO is “not ready to say” exactly when within that period the show will premiere.

Principal photography for the series began in the United Kingdom in mid-2025, with the first season expected to consist of eight episodes. Adult cast members confirmed include John Lithgow as Albus Dumbledore, while Dominic McLaughlin was cast as Harry Potter, Alastair Stout as Ron Weasley and Arabella Stanton as Hermione Granger in the series.

Long-awaited adaptation

The series, based on J.K. Rowling’s beloved novels, is being developed as a faithful adaptation rather than a direct continuation of the films. Each book in the seven-part saga is expected to receive its own season, allowing for more detailed storytelling than the original movies.

The Harry Potter series is penned and executive produced by Francesca Gardiner, with Mark Mylod serving as executive producer and directing several episodes. The show is being produced by HBO, in collaboration with Brontë Film and TV and Warner Bros Television. Executive producers also include J.K. Rowling, Neil Blair and Ruth Kenley-Letts of Brontë Film and TV, along with David Heyman of Heyday Films. Hans Zimmer has also come on board as the series’ composer.
