Who will be the next Lord Voldemort? Ralph Fiennes has his pick.

During an April 10 appearance on "The Claudia Winkleman Show," the "Conclave" star, 63, named the actor he thinks should take over his "Harry Potter" role in the upcoming HBO series.

"Tilda Swinton was mentioned somewhere as being a contender, and I think she would be amazing," he said.

Fiennes played Voldemort, the main villain of "Harry Potter," in the original film series that ran from 2001 to 2011, though he did not appear as the character until the fourth installment, "Harry Potter and the Goblet of Fire."

HBO's "Harry Potter" will be a new adaptation of the original books by J.K. Rowling featuring new actors. Most of the main cast of the series has been announced, though it has not yet been revealed who will play Voldemort.
