John Lithgow Confirms Role as Dumbledore in HBO’s Harry Potter Series

The Emmy-winning actor prepares for a decade-long commitment as the iconic wizard, with production set to begin in summer 2025.

John Lithgow has been officially cast as Albus Dumbledore in HBO's upcoming Harry Potter TV series, marking a major addition to the rebooted franchise.
The series will adapt each of J.K. Rowling's seven novels into its own season, aiming for a faithful and detailed portrayal of the books.
Lithgow, who is currently reading the Harry Potter novels for the first time, described the role as manageable due to Dumbledore's limited appearances.
The actor acknowledged the logistical challenges of filming in England and the long-term commitment required, as the series is expected to span nearly a decade.
No other casting decisions, including those for Harry, Hermione, and Ron, have been officially announced, though Paapa Essiedu is reportedly being considered for Snape.
