Who will be the new face of He-Who-Must-Not-Be-Named? Explore HBO's Harry Potter TV series casting, new leads, and the one major role still to be revealed.

AceShowbiz - The upcoming Harry Potter remake by HBO still has one major casting decision pending: the actor who will portray Lord Voldemort. More than 16 years after Warner Bros. concluded the original movie saga with Harry Potter and the Deathly Hallows Part 2, the studio is revisiting the beloved Wizarding World with a fresh adaptation. This time, instead of a film series, the story of the boy who lived will unfold as an extended TV series on HBO and HBO Max.
News about the remake first emerged in 2021, with showrunner Francesca Gardiner and director Mark Mylod taking the helm. As the project progressed, key casting announcements were made by May 2025. Dominic McLaughlin was named as the new Harry Potter, while Alastair Stout and Arabella Stanton were cast as Ron Weasley and Hermione Granger respectively. Veteran actors including John Lithgow, Janet McTeer, Paapa Essiedu, and Nick Frost joined the cast as Albus Dumbledore, Minerva McGonagall, Severus Snape, and Rubeus Hagrid.
Despite these exciting developments, one critical role remains unfilled: the Dark Lord himself, Lord Voldemort. This absence has sparked curiosity and speculation among fans, but there are good reasons why HBO can afford to delay announcing the actor for this pivotal character.
Nearly a year after revealing the new main trio, the HBO series has yet to cast Voldemort. Rumors have swirled around several high-profile actors, including Cillian Murphy, Damian Lewis, Paul Bettany, and Mark Strong. However, HBO has stayed silent on the matter, likely to avoid premature fan reactions given how passionate audiences are about this iconic villain.
Among those speculated, Cillian Murphy has explicitly denied any involvement in talks to portray Voldemort. Murphy’s recent acclaim for his Oscar-winning role in Christopher Nolan’s Oppenheimer had made fans hopeful, but he confirmed he would not be joining the Harry Potter project. This clarification helps clear the air and allows conversations to focus on other potential candidates without distraction.
Importantly, production of the Harry Potter TV series is already underway, yet HBO appears unpressed to finalize their choice for Voldemort soon. This relaxed timeline aligns with how the original movie franchise handled the character.
In the original cinematic series, Ralph Fiennes’ portrayal of Lord Voldemort did not debut until the fourth film, Harry Potter and the Goblet of Fire, released four years after the initial movie, Harry Potter and the Philosopher’s Stone. This means the character's introduction was delayed well into the franchise, providing HBO a precedent for waiting before casting their version of the Dark Lord.
The exact structure of the HBO adaptation is still unclear, but if it mirrors the original’s approach—one episode or season per book—then the show has at least several years before Voldemort’s character needs to appear. Given this, HBO can take its time to find the perfect actor to fill such an iconic and challenging role.
Moreover, if the series enjoys strong reception, Warner Bros. Television and its collaborators may extend its run beyond the original seven books. This potential longevity would further alleviate any urgency in casting the villain, as the story could unfold at a more leisurely pace over multiple seasons.
One of the key advantages of adapting a beloved book series like Harry Potter into a TV format rather than movies is the increased opportunity for in-depth storytelling. While the original films were constrained by runtime limits and the need to condense complex narratives into a couple of hours per movie, the series format allows for exploration of characters and subplots in far greater detail.
This expanded storytelling space not only benefits the development of protagonists but also opens doors to revisit lesser-explored facets of the novels. HBO’s series can delve deeper into the Wizarding World’s lore, character motivations, and relationships, enhancing the narrative richness compared to the original movies.
For the role of Voldemort, this means HBO has the luxury of time to carefully consider casting choices. Finding an actor who can meet or exceed the high bar set by Fiennes is a daunting task. Fans have long admired his compelling and chilling portrayal of the Dark Lord, making it essential that the new actor honors that legacy rather than rushing a premature announcement.
Ultimately, it seems wiser for HBO to hold off on revealing the new Voldemort until they are confident in their choice. Rushing this casting could lead to divisive fan reactions and damage the series’ reception. By taking a patient approach, the showrunners can ensure the Dark Lord is brought to life in a way that satisfies both longtime enthusiasts and new viewers alike.
The Harry Potter remake is currently slated to premiere on HBO and HBO Max in 2027. Until then, fans can look forward to more casting news and updates as the project continues its development.
