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 reports that a deal is imminent. This follows November reports suggesting Mark Rylance was the frontrunner for the role.
"We understand the significant interest surrounding this project and the resulting speculation," an HBO spokesperson stated. "We will only confirm casting decisions once contracts are finalized."
Lithgow's extensive filmography includes notable performances in The World According to Garp, Terms of Endearment, Footloose, Dexter, and The Crown.

The series will prioritize British talent, a decision potentially influenced by J.K. Rowling's reported involvement in the casting process.
Announced in April 2023, the Harry Potter adaptation promises a faithful, yet more in-depth exploration of the novels compared to the film series. Succession producers Francesca Gardiner and Mark Mylod (also a Game of Thrones veteran) are attached to direct and write.
