Irish actor Cillian Murphy has addressed recent rumors linking him to the role of Lord Voldemort in the upcoming Harry Potter television adaptation. Murphy, known for roles in Peaky Blinders and Oppenheimer, provided a clear response during interviews while promoting other projects.
Murphy was asked about speculation that he would portray the iconic antagonist in the HBO Harry Potter series. He responded, “I’m categorically not,” and added, “Can you make that the headline?” when discussing the matter with The Times.
The actor also noted that he had not followed the casting chatter closely and was taken by surprise that his name had circulated widely in connection with the part. “Being a personality is not what I am good at,” he told The Times. “It’s not healthy if you start to believe this s—, and I’m really bad at it too. I’m an incredibly average person, really.”

Murphy’s remarks appear to be the most definitive public comment on his involvement in the Harry Potter adaptation to date. They make explicit that he is not participating in the project as the Dark wizard, a character originally portrayed by Ralph Fiennes in the feature films.
Despite his denial, there is no official confirmation yet about who will play Voldemort in the new series. Cast lists for the adaptation include Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stour as Ron Weasley, among other roles announced by the production.
Background on the Rumor and Series Casting
Speculation about Cillian Murphy dates back several months, with some industry and fan sources naming him as a potential choice for the role of Lord Voldemort. At times, comments from individuals associated with the franchise seemed to fuel that speculation. For instance, original Voldemort actor Ralph Fiennes mentioned Murphy’s name. “I’m told [my shoes] are already filled, aren’t they? I think Cillian Murphy is very good. A very good choice.” Let’s Talk Film shared his statement in a TikTok that went viral, making many fans assume the Dark Lord had been chosen.

With Murphy’s denial of the rumor, casting decisions for the villain in the series remain unconfirmed by HBO and Warner Bros. Television. The production has repeatedly released partial cast lists for some key characters, but has not disclosed who will portray Voldemort or other major antagonists.
Casting for high‑profile roles in major adaptations often draws speculation long before studios make formal announcements. In this case, long‑standing interest in the Harry Potter franchise has led to sustained coverage about who will fill specific character parts.

Murphy’s comments reflect a broader trend in which actors sought for major adaptations attempt to clarify their involvement — or lack thereof — as production news circulates. His remarks provide clarity about his connection to the Harry Potter series, even as other casting elements continue to unfold.
At present, HBO and its partners have announced a planned release in 2027 for the Harry Potter television adaptation. The series is expected to cover the original book series across multiple seasons, with an ensemble cast portraying the next generation of familiar characters.
