Between the end of 2026 and the beginning of 2027, HBO plans to release the new TV series dedicated to the Harry Potter saga, the wizard born from the pen and imagination of the English writer JK Rowling . For all fans of the adventures of the boy played on the big screen by Daniel Radcliffe , this is great news. What do we know so far about this production? There are some hypotheses circulating about the cast, in particular regarding the role of Albus Dumbledore , the headmaster of Hogwarts, the school of magic attended by Harry and his friends. Who could play the role of Albus Dumbledore in the HBO Harry Potter TV series ?

Ever since HBO announced a Harry Potter TV series, there has been a lot of curiosity among industry insiders and fans. The production company hasn't said much about this project, which is inspired by Rowling's book series, which has become a cult on the big screen in the eight films produced by Warner Bros.

Filming will begin in the summer of 2025 and a release on the small screen is expected between the end of 2026 and the beginning of 2027. Great secrecy about the cast, which is an absolute mystery.

According to rumors that have come out in these hours, the new Albus Dumbledore , in the HBO TV series dedicated to Harry Potter, could be the American actor John Lithgow . The news has not been made official by the production company, but the 79-year-old actor would have anticipated everything in an interview given to ScreenRant. "It was a surprise for me too. I received the call while I was at the Sundance Film Festival for another film and it was not an easy decision, because I fear that this commitment will occupy the entire last chapter of my life . But I am very happy about it...".

HBO has not yet said anything about the production's cast , but in an official statement it stressed: "We appreciate that such a high-profile series generates a lot of rumor and speculation. As we proceed through pre-production, we will only confirm details as we finalize negotiations."

Previously, in the films dedicated to the role of Albus Dumbledore was played by Michael Gambon and Richard Harris , actors who have passed away.

Since HBO is keeping quiet, there have been many speculations about the cast for some time now. So far, the names that have been mentioned are Paapa Essiedu as Severus Snape, Sharon Horgan and Lesley Manville for the role of Deputy Headmistress Minerva McGonagall, and Brett Goldstein for Rubeus Hagrid.

Who will be the actors who will carry the heavy legacy of Daniel Radcliffe, Emma Watson and Rupert Grint , who respectively played Harry Potter, Hermione Granger and Ron Weasley? There are rumours about the possibility of seeing three young newcomers : the production company has launched a casting call for the young characters, to which more than 30,000 children and teenagers have responded.
