Last week, it was reported that John Lithgow was going to play the iconic wizard, and during an interview withScreen Rant,the actor confirmed he has been cast as Dumbledore in HBO’sHarry Potterseries. He said, “Well, it came as a total surprise to me. I just got the phone call up at the Sundance Film Festival for yet another film, and it was not an easy decision because it’s going to define me for the last chapter of my life, I’m afraid. But I’m very excited. Some wonderful people areturning their attention back toHarry Potter. That’s why it’s been such a hard decision. I’ll be about 87 years old at the wrap party, but I’ve said yes.”

Lithgow is the only actor officially cast for the Harry Potter television series at this point, but it has been reported thatPaapa Essiedu is HBO’s number one target to play Severus Snape. There has also been confirmation that auditions have taken placeto cast the lead roles of Harry Potter, Hermione Granger, and Ron Weasley, but at this point, it’s unknown who will be taking on those important roles.

TheHarry Pottertelevision series is expected to dedicate one full season per novel, giving HBO a lot of time to devote to each of JK Rowling’s books. That’s something thatHarry Potterfans hope will lead to characters and storylines that were neglected during the movies getting the opportunity to have some spotlight this time. The show is slated to release in late 2026 or early 2027, andit has been confirmed that filming of the episodes will commence in summer 2025 at Warner Bros. Studios Leavesdon in the United Kingdom, where the original movies were also filmed. Since filming is set to begin later this year, moreofficial cast announcements are expectedto be coming imminently.

Casting Lithgow will certainly raise some eyebrows amongst fans of the franchise because he is American. That was something that was widely avoided during the film series, asBritish actors were primarily cast for that role. However, it’s clear that HBO believes that Lithgow can take on the role, which isone of the most important in the franchisedue to how powerful Dumbledore is. However, there will also be no shortage of excitement fromHarry Potterfans now that the cast is starting to be revealed.
