Cillian Murphy’s name has come up a lot, with rumors that he will play either Lord Voldemort or Professor Quirrell. “I May Destroy You” alum Paapa Essiedu is strongly rumored to be playing Severus Snape, while Ted Lasso’s Brett Goldstein has been named as a possibility for portraying Rubeus Hagrid.

It seems John Lithgow spilled the (Bertie Bott's Every Flavor) beans about his involvement in HBO's in-the-works 'Harry Potter' series. 'A total surprise to me,' he says.

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."
