The role of Voldemort in the upcoming HBO Harry Potter series has not been officially announced yet as of early 2026, so there is no confirmed actor at this time.

Quick Scoop

  • HBO’s new Harry Potter TV series is aiming to debut around 2027, with casting still being rolled out piece by piece.
  • The studio has confirmed that Voldemort has been cast internally, but they are deliberately keeping the actor’s identity secret for now.
  • Ralph Fiennes, who played Voldemort in the original films, has implied that “his shoes are already filled,” suggesting someone has the role, but he did not name them.
  • Various rumors have linked names like Cillian Murphy and Paul Bettany to the part, but both remain unconfirmed, and at least one has publicly denied being cast.

What’s rumor vs. reality?

  1. Rumors and hints
    • A viral interview clip of Ralph Fiennes led many fans to believe Cillian Murphy had been chosen, especially after Fiennes called him a “very good” choice.
 * Fan sites and entertainment outlets have reported “insider claims” that Voldemort is locked in, but those reports all agree the name is being kept under wraps.
  1. What’s actually confirmed
    • Official channels (HBO/Max, major studio announcements) have not publicly revealed the Voldemort actor yet.
 * News coverage consistently describes the casting as done or in progress, but emphasizes that the identity is still secret.

Trending context & fandom buzz

  • Online forums and social media are full of fantasy casting: fans debate whether the show should go for a prestige drama actor (Murphy-type), a theater veteran, or a lesser-known face who can grow with the series.
  • Entertainment sites are treating the Voldemort reveal as one of the show’s big “event announcements,” likely being saved for closer to the first season where he actually appears (around the Goblet of Fire timeline).

Bottom line

Right now, all we truly know is: Voldemort has likely been cast, but the actor’s name has not been officially revealed to the public yet.

Anything more specific you see (like a definite name) should be treated as speculation until HBO or the production officially confirms it. Information gathered from public forums or data available on the internet and portrayed here.
