HBO is reportedly in advanced negotiations with acclaimed actor John Lithgow, known for his role as Lord Farquaad in Shrek, to portray the iconic Hogwarts headmaster Albus Dumbledore in their upcoming Harry Potter series. While HBO remains tight-lipped, Variety sources suggest a deal is imminent. This development follows November reports naming Mark Rylance as the frontrunner for the Dumbledore role.

"We understand the significant interest surrounding this project and the resulting speculation," an HBO spokesperson stated. "As pre-production continues, we'll only confirm casting details upon finalization of contracts."

Lithgow's extensive filmography includes notable roles in The World According to Garp, Terms of Endearment, Footloose, Dexter, and The Crown, showcasing his versatility and range.

The series will prioritize British talent, mirroring the films. This aligns with J.K. Rowling's reported involvement in the casting process.

Announced in April 2023, the Harry Potter adaptation promises a faithful and more detailed exploration of the novels compared to the film series. Francesca Gardiner and Mark Mylod, known for their work on Succession and Game of Thrones respectively, will serve as producers and directors.
