Cillian Murphy has firmly dismissed rumors that he will portray Voldemort in HBO’s upcoming Harry Potter series, leaving the identity of the Dark Lord’s actor still undisclosed. As fans await the show’s debut, Murphy’s denial clarifies speculation surrounding his involvement in the coveted role.
Murphy directly refutes Voldemort casting claims
When confronted with the question of whether he was cast as Voldemort, Murphy responded without hesitation, putting an end to the rumors.
“I am categorically not. Can you make that the headline?”
He emphasized his reluctance to engage with fame and the spotlight that accompanies high-profile roles, explaining his preference to remain grounded and avoid becoming a celebrity persona. Murphy views the surrounding hype and attention as a trap and focuses on acting rather than public recognition.
Previous denials and respect for Ralph Fiennes
This is not the first time Murphy has addressed these conjectures. He mentioned on the Happy Sad Confused podcast that his children occasionally bring such stories to his attention, but there has been no official confirmation of his involvement. Murphy also acknowledged Ralph Fiennes, who famously originated the role of Voldemort, with deep admiration, recognizing Fiennes as an acting legend and a daunting benchmark for anyone attempting the character.
Ralph Fiennes supports the idea of Murphy as Voldemort
Interestingly, Ralph Fiennes himself expressed enthusiasm for the notion of Murphy stepping into the Dark Lord’s shoes. During an appearance on Watch What Happens Live last year, Fiennes praised Murphy’s talent and openly supported the suggestion.

“He is a fantastic actor… I actually think that is a wonderful suggestion. I would be all in favor of Cillian.”
Voldemort’s role already cast, reveal expected in 2027
Behind the scenes, sources indicate the actor playing Voldemort has already been chosen and will feature in multiple episodes throughout the series. However, the production team plans to keep this casting secret until the first season’s release in 2027, maintaining the mystery around the Dark Lord’s portrayal for now.
Other circulating rumors involving Murphy
Aside from the Voldemort speculation, an industry insider suggested on Patreon that Murphy might be considered for the role of Professor Quirinus Quirrell in the new series. While this remains unconfirmed, it has gained some attention within fandom circles.
