HBO Shares Spellbinding Casting Update on Harry Potter TV Series

HBO shared a casting update for its Harry Potter TV series adaptation after rumors began swirling that John Lithgow was in final negotiations to play Dumbledore in the show, set to premiere in 2026.

Accio Harry Potter cast details. 

HBO shared insight into the casting process of its highly anticipated Harry Potter TV adaptation after speculation began swirling that John Lithgow—who’s starred in shows like Dexter, as well as movies such as Conclave and Interstellar—was in final negotiations to portray Professor Albus Dumbledore in the series, which is expected to hit screens in 2026. 

“We appreciate that such a high-profile series will draw a lot of rumor and speculation,” HBO said in a Feb. 12 statement to Deadline. “As we make our way through pre-production, we will only confirm details as we finalize deals.”

E! News reached out to HBO and a rep for Lithgow for comment but has not heard back. 

And while HBO didn’t confirm whether the role of Dumbledore—previously played by the late Richard Harris and Michael Gambon in the 2001-2011 film franchise—has been filled, the network has shared several other magical details about the high-profile J.K. Rowling adaptation, which was designed to run for over a decade.

For one, Francesca Gardiner—who’s previously written for dramas including His Dark Materials and The Rook—created the series and will serve as its showrunner.  

Meanwhile, Mark Mylod—who’s behind the 2022 psychological thriller The Menu—will direct and executive produce the show. 

And fans of the book will be especially pleased with HBO’s take on the franchise, as the producers announced in a 2023 press release that it will be a “faithful adaptation” of Rowling’s novels.

As for whether film series cast members Daniel Radcliffe, Emma Watson, Rupert GrintTom Felton and Ralph Fiennes will be returning to Hogwarts in some capacity? Radcliffe doesn’t want muggles to get their hopes up

“I think they very wisely want to [have] a clean break,” he told E! News in May. “And I don’t know if it would work to have us do anything in it.” 

Radcliffe continued, “I’m very happy to just watch along with everyone else.”

But that doesn’t mean the door is completely closed on him re-entering the wizarding world. After all, the 35-year-old remained coy when asked exactly how he’d respond if HBO did ask him to make an appearance. 

“I’m gonna be a politician about this,” he quipped, “and not deal in hypotheticals.”
