HBO is accelerating its new Harry Potter TV series, and there's exciting news on the casting front: John Lithgow has been confirmed as the new Professor Dumbledore. HBO has been searching for the right actor to fill Dumbledore's shoes, and it seems they've found their man. In an interview with ScreenRant, Lithgow shared that he accepted the role, which he describes as defining the "last chapter" of his life.

"I was completely taken aback when I received the call at the Sundance Film Festival. It was a tough decision because this role will define me for the rest of my life," Lithgow remarked. He added, "But I'm thrilled. Some incredible people are bringing Harry Potter back to life. That's what made the decision so challenging. I'll be about 87 at the wrap party, but I've agreed to do it."

HBO's strategy involves re-adapting all of J.K. Rowling's books into a TV format, with a fresh cast portraying beloved characters such as Harry Potter, Hermione Granger, Ron Weasley, and the Hogwarts students. J.K. Rowling will serve as an executive producer alongside Neil Blair and Ruth Kenley-Letts.

Despite Lithgow's verbal confirmation, the absence of a complete cast suggests that the series is still a while away from production.

John Lithgow is a seasoned actor, renowned for his role as Dick Solomon in the sitcom "3rd Rock from the Sun." He also garnered critical acclaim and an Emmy for his portrayal of Winston Churchill in the first season of Netflix's "The Crown."
