Cillian Murphy as Voldemort? The News Fans Want to Hear — But There’s a Catch

He might just be too powerful to be tempted.
This actor is probably the one whom many see as the perfect replacement for Voldemort in the upcoming Harry Potter series — the only one who could possibly follow Ralph Fiennes’ iconic performance without fading into the shadows. And now, with rumours swirling once again about Cillian Murphy's possible casting, fans are diving into heated discussions. Not about if he could do it (that’s almost a given), but why he might never agree to take part.
"He’s literally the only actor who can pull off Voldemort without CGI," one user gushes on Instagram. Another calls it "cold-blooded casting" — meant in the best way. But over on Reddit, it gets more cautious: "Fantastic choice, but he’s too famous these days. I doubt he’d commit to four seasons of a TV show."
There’s the rub. While Cillian Murphy’s haunted intensity seems made for the Dark Lord, fans worry he’s simply outgrown the role — too big, too busy, or too principled for a Rowling-adjacent project. He’s perfect, sure. But perfection doesn’t always come with a contract.
The series, set to drop in 2027 on Max, will span seven seasons — one per book — with filming starting next year. Almost the entire cast has already been locked in, including the new faces of Harry, Ron, and Hermione. All that’s left now is the darkest one of all.
