Despite a wave of viral theories suggesting that the role of He-Who-Must-Not-Be-Named has already been filled, HBO Chairman and CEO Casey Bloys recently set the record stone straight. Speaking with Variety, Bloys dismissed the online chatter, clarifying that the network is nowhere near a decision and urging fans to take any confirmed leaks with a massive grain of salt.
“I don’t even know who we’re casting. I really don’t!” Bloys admitted, effectively resetting the clock for a fandom that has spent months debating who could possibly follow in Ralph Fiennes‘ legendary, serpentine footsteps. As production on the first season continues, the vacancy has only fueled more creative campaigning from fans looking for the perfect blend of menace and gravitas. Here, 10 fan-cast favorites.

The “Oppenheimer” Oscar winner is currently the overwhelming favorite across social media, with fans pointing to his ability to project a chilling, silent intensity. Even Ralph Fiennes has given the Irish actor his seal of approval, calling him a “fantastic” choice for the reboot. While Murphy has politely played down the rumors in recent interviews, his history of playing complex, high-stakes figures makes him the logical frontrunner for a more psychological take on the Dark Lord.
Benedict Cumberbatch
Few actors possess a voice as naturally imposing as the man who brought Smaug the dragon to life. Supporters of this casting argue that his sharp, angular features and proven track record in massive franchises would give the series an immediate sense of prestige. Cumberbatch has a unique talent for portraying intellectual arrogance, a trait that is essential for a villain who truly believes himself to be the greatest wizard of all time.
Bill Skarsgård
Having already terrified a generation as Pennywise in “IT,” this actor is a popular pick for those who want a more transformative and visceral version of Voldemort. He has demonstrated a remarkable comfort with heavy prosthetics and otherworldly physicalities, which could be vital for the character’s snake-like evolution. Fans are particularly excited by the prospect of him playing the manipulative Tom Riddle in flashbacks before transitioning into the monstrous Dark Lord.
Matt Smith
Following his villainous turn in “House of the Dragon,” the British star has become a staple of fan-casting lists for his “alien” and unpredictable screen presence. There is an unsettling quality to his performances that many feel matches the book’s description of a man who has pushed his soul to the absolute limit. Though Smith has expressed humility at the idea of following Fiennes, his ability to command a room with a single look makes him a top-tier contender.
Tom Hiddleston
While he is world-famous for playing a god of mischief, many believe Hiddleston’s theatrical background makes him perfect for the high drama of the “Harry Potter” universe. He excels at playing characters who are driven by a deep sense of rejection and a thirst for power, mirroring Voldemort’s own origins in the orphanage. His casting would likely bring a Shakespearean weight to the series, focusing on the tragedy of a man who chose darkness over connection.

The “Vision” actor has long been cited for his ability to play chillingly calm characters with a hidden layer of explosive violence. With his tall, lean frame and experience in high-concept genre work, he fits the physical profile of the Dark Lord as described in J.K. Rowling’s later novels. Bettany has often been the subject of secret casting rumors, and while he has denied any calls from HBO, the fan demand for his involvement hasn’t wavered.
Mark Strong
Known for being one of Hollywood’s most reliable and intimidating antagonists, Strong is a choice that many feel is long overdue for a major fantasy franchise. He possesses a natural authority and a commanding voice that would make the Malfoy faction’s fear of him feel entirely earned. Because he can transition seamlessly between suave sophistication and pure brutality, he represents a safe yet undeniably effective pick for the network.
Andrew Scott
Best known for his electrifying turn as Moriarty in “Sherlock,” Scott is the go-to suggestion for fans who want a Voldemort that feels genuinely dangerous and slightly unhinged. He has a way of making every line feel like a calculated threat, which could help differentiate this version of the villain from the film adaptations. Seeing him go toe-to-toe with the new Dumbledore, John Lithgow, would provide the kind of heavy-hitting acting duel HBO is known for.
Nicholas Hoult
By leaning into the “Tom Riddle” side of the character, some fans believe Hoult could provide a haunting portrayal of a man who lost his humanity piece by piece. He has spent the last few years taking on increasingly daring and eccentric roles, proving he is far more than just a leading man. Casting a slightly younger actor for the role could allow the show to lean more heavily into the Horcrux flashbacks, showing Voldemort’s rise to power in real-time.

After his standout performance as the terrifying Vecna in “Stranger Things,” Bower has proven he can lead a massive supernatural production from behind layers of makeup. Interestingly, he has already appeared in the wizarding world as a young Gellert Grindelwald, but fans are eager to see him take on an even larger, more central role. His ability to blend youthful charm with ancient, creeping evil makes him one of the most exciting suggestions for the series.
