Author: Jack Apr 05,2025

HBO is reportedly in the final stages of negotiations with John Lithgow, known for his role as Lord Farquaad in Shrek, to portray the iconic Hogwarts headmaster Albus Dumbledore in the much-anticipated Harry Potter reboot series. According to Variety, Lithgow is on the verge of securing this pivotal role, although HBO has yet to officially confirm the casting. This development comes as a surprise, especially after Variety previously reported in November that Mark Rylance was the top choice for Dumbledore.

A spokesperson from HBO commented on the swirling rumors, stating, "We appreciate that such a high-profile series will draw a lot of rumor and speculation. As we make our way through pre-production, we will only confirm details as we finalize deals." This cautious approach underscores the network's strategy to keep casting details under wraps until contracts are signed.

John Lithgow's extensive acting resume includes notable roles in films like The World According to Garp, Terms of Endearment, and Footloose, as well as television series such as Dexter and The Crown. His potential casting as Dumbledore adds a significant layer of excitement to the project.

Despite the buzz around Lithgow's potential role, HBO's casting process remains largely secretive. The network is also on the hunt for actors to play Harry, Hermione, and Ron, and has reportedly found its Severus Snape in Paapa Essiedu. The series aims to maintain a focus on British talent, a decision influenced by the involvement of the original author, J.K. Rowling, who is "fairly involved" in the casting process.

Announced in April 2023, the Harry Potter series promises to be a "faithful adaptation" of the beloved novels, offering a more "in-depth" exploration of the story than what was possible in the two-hour film format. The project is in capable hands, with Succession producers Francesca Gardiner and Mark Mylod set to direct and write. Mylod's previous work on Game of Thrones adds to the anticipation surrounding this new adaptation.
