Cillian Murphy Reportedly Eyed For Professor Quirrell Role in HBO ‘Harry Potter’ Series

HBO’s reboot of the beloved Harry Potter epic was announced in April 2023, initially inspired as collateral for the newly announced Max Original brand, but later promoted to HBO’s primetime, tentpole release slot. Rumored castings of Professor McGonagall and Professor Snape appeared a couple of months ago with Janet McTeer and Paapa Essiedu named, respectively; and Phoebe Waller-Bridge reported for the role of Aunt Petunia Dursley yesterday. We may now have our first glance at our p-p-p-p-poor, stuttering Professor Quirrell.

In July 2024, it was announced that His Dark Materials writer Francesca Gardiner would show-run the show, with Mark Mylod (The Menu) pulled in to head-direct episodes of the first season. The two previously worked together on Succession. The writer’s room for the show grew last October, adding Laura Neal, Andy Greenwald, and Josephine Gardiner to the mix.

According to reliable leaker DanielRPK, HBO and Warner Bros. are reportedly eyeing Oppenheimer star and Academy Award-winner Cillian Murphy for the plot-twist villain in the first installment of this saga. Murphy is currently starring in the upcoming Peaky Blinders film. Voldemort actor Ralph Fiennes, who is nominated for an Academy Award for his performance in Conclave, recently named Murphy as his top candidate to play Voldemort in the new TV Show.

Production for the show begins this Summer at Warner Bros. Studios Leavesden, aiming for a Late 2026 release date. Casting for The Golden Trio began last September and isn’t expected to be finalized and announced until after April 2025.

HBO promises that the show will be a “faithful and book-accurate adaptation” that will take 10 years to complete. Warner Bros.’ Harry Potter producers J.K. Rowling, Neil Blair, Ruth Kenley-Letts, and David Heyman will all return to executive produce the series with Gardiner and Mylod.
