Who’s Going to Be in the ‘Harry Potter’ Series? See the Rumored New Actors Side-by-Side with the Original Cast

The new Harry Potter show has been keeping its chamber of secrets closed when it comes to casting — until now.

The beloved book series by J.K. Rowling will be adapted for the screen once again, but this time it’ll be getting a more in-depth treatment as a TV show, with each season slated to capture one of the seven books, per Bloomberg.

While some of the original cast have spoken out about their hopes to return to the wizarding world, others have confirmed they didn’t have plans to reprise their roles.

“Like the rest of the world, [I’m] very excited to watch as an audience member,” Daniel Radcliffe, who originated the titular role, told E! in May 2024. “I don’t know if it would work to have us do anything in it.”

Now, John Lithgow has been the only cast member confirmed so far, while a few actors are nearing deals, with Deadline reporting in March 2025 that Nick Frost, Janet McTeer and Paapa Essiedu are in talks.

So who is joining the cast of the new Harry Potter series? Here’s a look at the actors that have been cast so far side-by-side with those who originated the roles.
