Actor Cillian Murphy, known for his outstanding performances in “Oppenheimer” and “Peaky Blinders,” recently addressed circulating rumors about his involvement in the upcoming Harry Potter reboot. Despite widespread speculation that he would portray the villain Lord Voldemort in the new HBO series currently filming in the UK, Murphy firmly denied these claims. His clear response puts to rest rumors linking the celebrated actor to the reboot cast ahead of its anticipated 2027 release.
Addressing Rumors of Joining the Harry Potter Reboot as Voldemort
The entertainment world has been abuzz with talk that Cillian Murphy would replace Ralph Fiennes as Lord Voldemort in the Harry Potter reboot. This speculation started in January 2026 when Ralph Fiennes suggested in an interview with Let’s Talk Film that the role intended for him had been filled and hinted that Murphy was the new choice. Fiennes remarked,
“I think Cillian Murphy is very good. A very good choice,”
further sparking interest in Murphy’s casting. However, Murphy decisively denied these rumors during a recent interview with The Times. He stated,
“I’m categorically not. Can you make that the headline?”
putting an end to the swirling conjecture about his participation as the dark wizard.
Current Status and Cast of the Harry Potter Reboot Series
The highly anticipated Harry Potter reboot is underway, filming primarily in the United Kingdom. Set for release on HBO in 2027, the series introduces a new generation of young actors stepping into iconic roles. Dominic McLaughlin plays Harry Potter, with Alastair Stout as Ron Weasley and Arabella Stanton taking on Hermione Granger. These roles were famously portrayed by Daniel Radcliffe, Rupert Grint, and Emma Watson in the original film series, who remain fan favorites.
The reboot’s supporting cast features esteemed actors too, including Janet McTeer as Professor McGonagall and John Lithgow as Headmaster Dumbledore. Nick Frost joins as Hagrid, while Paul Whitehouse plays Hogwarts’ caretaker Argus Filch. Johnny Flynn is cast as Lucius Malfoy, Warwick Davis continues in his original role as Filius Flitwick, and Paapa Essiedu portrays Severus Snape. Notably, Warwick Davis is the only returning actor from the original films to reprise his character.

Reflecting on those formative years, Murphy shared to The Guardian in 2016,
“And it was around the same time I met my wife. She came on tour with us. It was so exciting, 20 years ago or whatever it was — we were all just kids, trying to find our way — but such a special, special time.”
This personal aspect reveals the grounded nature Murphy maintains despite his international stardom.
