Cillian Murphy Shuts Down Voldemort Casting Rumors

Cillian Murphy has put an end to months of wizarding-world speculation. The Oppenheimer and Peaky Blinders star has definitively denied that he will play Lord Voldemort in HBO’s upcoming Harry Potter television reboot.

Rumors had swirled online for months, especially after Ralph Fiennes — who portrayed the Dark Lord in the original film series — suggested Murphy would be a “very good choice” and appeared to believe the casting was already set. Now, Murphy has made it clear: he is not stepping into He Who Must Not Be Named’s robes.

How the Rumor Took Hold

Fan casting around Murphy intensified following his Oscar-winning turn in Oppenheimer. His gaunt features and chilling screen presence made him a popular pick for Voldemort across social media. Even Harry Potter and the Sorcerer’s Stone director Chris Columbus publicly backed the idea, calling Murphy one of his favorite actors.

The speculation gained further traction when Fiennes seemed to treat the casting as a done deal. That comment lit up fantasy forums and headlines alike. But Murphy has now delivered what many fans will see as a final word, firmly shutting the door on the possibility, as reported in The Independent and echoed by outlets including GamesRadar.

What This Means for HBO’s Reboot

HBO’s ambitious adaptation plans to retell all seven of J.K. Rowling’s novels across multiple seasons, with a targeted premiere in early 2027. Dominic McLaughlin, Arabella Stanton, and Alastair Stout have been cast as Harry, Hermione, and Ron. Major adult roles, including Voldemort, remain unconfirmed.

The Dark Lord does not fully appear in the books until Harry Potter and the Goblet of Fire, meaning HBO has time before making its final decision. Still, casting news has become a lightning rod for fans eager to see how this new version will distinguish itself from the beloved films.

The reboot has already sparked intense conversation, from debates around J.K. Rowling’s involvement to speculation about future spin-offs, as previously explored when HBO eyed Harry Potter spinoffs ahead of the 2027 reboot. Even former cast members have weighed in, with Daniel Radcliffe backing HBO’s new Harry Potter star as the torch passes to a new generation.

For now, one thing is certain: Voldemort remains uncast, and Cillian Murphy is officially out of the running. The question that lingers for readers and viewers alike is who will dare to follow in Fiennes’s footsteps when the Dark Lord finally rises again on screen.
