The upcoming HBO TV adaptation of the Harry Potter books still has something shaped like a release window, with HBO CEO Casey Bloys affirming that it will arrive in early 2027.
“Well, we’ve been saying 2027,” Bloys said in an interview with Deadline when asked if HBO had narrowed the release window. “I would say, to narrow it down to some extent, early 2027. And now you’re going to ask, does that mean January, February, March, April, that we’re not ready to say. I’ll say early 2027.”
We first heard about an early 2027 release window for Harry Potter way back in 2024, but given how uncertain it sounded then, this affirmation from Bloys helps firm things up a bit.
That was the only question and comment on the Harry Potter series from the interview. But we do know quite a bit of other information about the upcoming show, including much of its cast. We know that the main trio of heroes; Harry, Ron, and Hermione, will be played by Dominic McLaughlin, Alastair Stout, and Arabella Stanton, respectively. John Lithgow will portray Albus Dumbledore, Paapa Essidu joins as Severus Snape and Katherine Parkinson will be Molly Weasley. Sherlock actress Louise Brealey will be the series’ Quidditch teacher Madam Rolanda Hooch, Game of Thrones’ Anton Lesser is Garrick Ollivander, Bertie Carvel will play Cornelius Fudge, and Bel Powley and Daniel Rigby will portray the Dursleys, Petunia and Vernon. Nick Frost is Rubeus Hagrid, who we got a first look at in costume last July, Janet McTeer is Minerva McGonagall, Luke Thallon will be Quirinus Qirrell, and Paul Whitehouse is Argus Filch.
We’ve also seen some early set photos from the London Zoo and caught a glimpse of Lithgow in costume, and we just recently learned that Hans Zimmer will score the series.
