"I'll be about 87 years old at the wrap party, but I've said yes," said the actor, who will take on the beloved role for HBO's Harry Potter series

John Lithgow delightfully confirmed his involvement in the upcoming Harry Potter TV show during an interview. While speaking with Screen Rant, he recalled just how he found out he landed the gig, before sharing his feelings about signing on.

Lithgow will join showrunner Francesca Gardiner and series director Mark Mylod for the upcoming series. No other cast members have been announced so far, but in September 2024, Warner Bros. announced an open casting call for Harry, Ron, and Hermione— aka future wizards who will be lucky to learn from Lithgow.
