The "Conclave" actor, 79, said the casting "came as a total surprise," adding that the decision to take up the role in the new HBO series did not come easy.

"I just got the phone call up at the Sundance Film Festival for yet another film, and it was not an easy decision, because it's going to define me for the last chapter of my life, I'm afraid," said Lithgow. "But I'm very excited."

"Some wonderful people are turning their attention back to Harry Potter," he added.

Speaking to the potential length of the commitment, the six-time Emmy winner said, "That's why it's been such a hard decision. I'll be about 87 years old at the wrap party, but I've said yes."

HBO has not confirmed the casting.

The network said in a statement to "Good Morning America" Tuesday, they "appreciate that such a high-profile series will draw a lot of rumor and speculation. As we make our way through pre-production, we will only confirm details as we finalize deals."
