It was practically an open secret, and now, thanks to its confirmation, it's a reality. The rumors circulating about John Lithgow potentially taking on the iconic role of Albus Dumbledore have finally been confirmed . The actor himself broke the news in a recent interview, so we can now officially say we have a new face for the beloved and wise headmaster of Hogwarts.
HBO bets on a complete adaptation
The Harry Potter series on HBO aims to be a faithful adaptation of the books, exploring in detail aspects that the films left out. According to official information, the intention is to produce seven seasons , each based on a novel in the saga.
The casting process is already underway to find the actors for the main trio: Harry, Hermione, and Ron . Furthermore, HBO has confirmed that key figures from Succession , such as Francesca Gardiner and Mark Mylod, will be involved in the project's development.
The challenge of embodying Albus Dumbledore
John Lithgow joins a prestigious list of actors who have portrayed the illustrious headmaster of Hogwarts. In the first films, the character was played by Richard Harris (pictured below), who sadly passed away in 2002. Michael Gambon then took over the role until the end of the film saga. More recently, Jude Law portrayed a younger version of Dumbledore in the Fantastic Beasts film series.

The veteran American actor, known for his roles in films and series such as Dexter , Interstellar , and The Crown , revealed that he received the offer unexpectedly while at the Sundance Film Festival. According to him, accepting the role was a difficult decision , as it involves a significant commitment in the final stage of his career: "It wasn't an easy decision because it's going to define the last chapter of my life, I'm afraid. But I'm very excited." At 79 , Lithgow is taking on a role that could last him almost a decade if the series continues as planned. "I'll be about 87 when the wrap party comes around, but I said yes," he stated.
Filming and release date
While many details are still to be revealed, HBO has already announced some key dates. Filming for the series will begin in the summer of 2025 , and the first season is expected to premiere in late 2026 or early 2027.
Meanwhile, Lithgow continues to add projects to his career. Currently, the actor is part of the cast of Conclave , a film nominated for several Academy Awards, and he also has the psychological thriller The Rule of Jenny Pen awaiting release.

The announcement of John Lithgow as Albus Dumbledore marks a significant moment in the production of the Harry Potter series, and we have no doubt that his participation will bring a new dimension to the character. Now, fans eagerly await the reveal of the rest of the cast and more details about what promises to be one of the most ambitious adaptations in recent years on the Max platform.
