In an interview with Screen Rant, Lithgow said that he has accepted the role of the Hogwarts head wizard in HBO’s forthcoming series: “I’ll be about 87 years old at the wrap party.”

The Emmy-winning actor, hot off a SAG Award for "Conclave," said playing the Hogwarts headmaster would "define me for the last chapter of my life."

Albus Dumbledore’s half-moon spectacles will be handed down to none other than John Lithgow.
