Cillian Murphy has firmly denied rumors that he will portray Voldemort in HBO’s upcoming Harry Potter series, clarifying the speculation amid ongoing secrecy around casting. As fans anticipate the show’s release in 2027, the identity of the actor playing the Dark Lord remains officially undisclosed.
Murphy’s Clear Refusal to Play Voldemort
When directly confronted with the question of whether he is taking on the role of Voldemort, Cillian Murphy responded without hesitation. He insisted,
“I am categorically not. Can you make that the headline?”
underscoring his desire to put an end to the rampant conjecture. Beyond the denial, Murphy expressed disinterest in becoming enveloped in celebrity culture, describing the attention and ongoing rumors as a “trap” he chooses not to engage with, emphasizing that he prefers living as an ordinary person who simply focuses on acting.
Previous Denials and Praise for Ralph Fiennes
This is not the first time Murphy has addressed these swirling rumors. During an appearance on the Happy Sad Confused podcast, he acknowledged that his children sometimes alert him to the speculations but stressed that none of it is founded on official information. Murphy also paid tribute to Ralph Fiennes, saying
“he is an absolute acting legend”
and admitting it would be difficult for anyone to live up to Fiennes’ iconic performance as Voldemort. He wished good luck to whoever eventually assumes the role.

Ralph Fiennes Supports the Idea of Murphy as Voldemort
In an intriguing turn, Ralph Fiennes himself voiced support for Murphy possibly taking over the role. On the show Watch What Happens Live, Fiennes praised Murphy, describing him as “a fantastic actor” and adding,
“I actually think that is a wonderful suggestion. I would be all in favor of Cillian.”
Despite this approval, Murphy’s denial remains firm.
