Casting Voldemort For HBO’s Harry Potter: 10 Actors Who Haven’t Been Mentioned Yet

The actor chosen to play Voldemort in the new HBO Harry Potter series will face a lot of pressure. Tom Marvolo Riddle is a hugely famous movie villain, and Ralph Fiennes’ performance has become the standard for many viewers.

It’s crucial to get the casting right for Voldemort’s backstory, especially now that the series has more time to explore his origins. While well-known actors like Cillian Murphy and Paul Bettany have been mentioned, many other talented British actors could bring a more compelling and unique take to the role.

Jefferson Hall

Jefferson Hall gained recognition for his dual role as the twins Jason and Tyland Lannister in House of the Dragon. He convincingly portrayed both a physically imposing and arrogant twin, and a quieter, more calculating one. This versatility – showing he can play both openly intimidating characters and those who work subtly behind the scenes – makes him a strong fit for the role of Voldemort.

Hall could depict the Dark Lord as more than just a powerful, frightening figure. He could show him as a clever and composed strategist who inspires fear through his commanding presence, intelligence, and quiet threats. This blend of intensity and control would make his portrayal of Voldemort both scary and realistic.

Tom Burke

Tom Burke is a talented actor who consistently gives nuanced and compelling performances. He skillfully portrayed Orson Welles in Mank, capturing the director’s confidence, charisma, and imposing nature. More recently, as Praetorian Jack in Furiosa, Burke was chillingly calm and controlled, creating a quietly threatening character who commanded respect without needing to shout.

Tom Burke naturally projects intelligence, a key quality for Voldemort, who is a cunning planner and driven by strong beliefs. Burke wouldn’t portray Voldemort simply as a frightening monster; he’d show a man whose intelligence and pride gradually transform into something truly terrifying – a cold, calculating Dark Lord who commands attention in the Harry Potter TV series. He’s able to convincingly draw people in, not just inspire fear.

Nick Mohammed

Nick Mohammed is well-known for playing Nathan Shelley on Ted Lasso, a character who unexpectedly turns against Ted because of envy. Though often viewed as a sympathetic figure, Mohammed has subtly shown Nathan’s capacity for more complicated and even unsettling behavior, which makes him a surprisingly compelling pick to play Tom Riddle.

Some viewers might initially question this casting choice, but it ultimately makes sense. The actor deeply grasps the themes of inner conflict, hidden emotions, and brokenness. His performance would also enrich the portrayal of Slytherin, moving beyond simple prejudice and offering a more nuanced understanding of Voldemort’s world and motivations within the series.

Rafe Spall

Rafe Spall is a talented British actor who works in film, television, and voice acting. He often portrays characters who are a bit anxious, intense, or have difficult moral choices. Spall is known for being charming, intelligent, and bringing a unique, slightly quirky energy to his performances, making him captivating in a wide range of roles.

Whether it’s leading a horror film like The Ritual, playing a complex character in Hustle, or delivering a standout performance in the Black Mirror episode “White Christmas,” Spall consistently shows he can play characters who are both likable and subtly threatening.

These strengths make Spall a surprisingly good fit for the role of Voldemort. He portrays the Dark Lord with a combination of quiet intelligence and sudden, frightening energy, creating a character who is both smart and disturbingly human – all without exaggerated performance techniques.

Sophie Okonedo

Sophie Okonedo is a highly talented British actress who consistently delivers powerful and nuanced performances in a wide range of roles, from dramatic to thrilling and historical. She naturally conveys intelligence, strength, and a hint of danger – qualities that would make her an ideal choice to play Voldemort.

Naomi Okonedo’s performances show she excels at playing complex, calculating characters. In Criminal: UK, her portrayal of Dr. Robyn Sampson highlights a similar strategic intelligence to Tom Riddle, and as Tatiana in Æon Flux, she embodies a powerful, ruthless presence that doesn’t rely on flashy displays. She can captivate an audience with subtle movements, making her a perfect fit for a smart, driven villain like a Dark Lord.

Her acting subtly shows intelligence, making her character’s schemes feel realistic and her moments of fear truly frightening. She could play the role of Slytherin’s heir as either a purely evil mastermind or a charming, persuasive leader, which gives HBO options for a fresh take on the character without losing the sense of power and menace he possesses.

Richard E. Grant

Richard E. Grant is a well-known British actor with a strong screen presence and a unique voice. He’s skilled at playing a wide range of roles, often bringing to life characters who are well-spoken, authoritative, a little unusual, and able to be both charming and intimidating. This makes him a perfect choice to play Voldemort in a new take on the story.

Richard E. Grant excelled at playing powerful and intimidating characters, as seen in his role as General Pryde in Star Wars: The Rise of Skywalker. He also comfortably portrayed complex and unusual figures, like Izembaro in Game of Thrones, Classic Loki in Loki, and in a guest appearance on Doctor Who, demonstrating his versatility across different genres.

Hugh Grant’s acclaimed performance as Jack Hock in the 2018 film Can You Ever Forgive Me? showed his ability to play charming but flawed characters. While he’s 68, his strong presence, intelligence, and seriousness could make him a uniquely compelling and memorable villain for HBO’s planned Harry Potter series.

Kristin Scott Thomas

As a huge cinema fan, if HBO were to reimagine Voldemort, Kristin Scott Thomas would be my absolute choice. I’ve loved her work in films like Gosford Park and The English Patient, but more recently, her role as Diana Taverner in Slow Horses really cemented her ability to play icy, powerful, and frankly, intimidating characters. She just has this incredible presence – someone who can seem polite while still being completely terrifying. It’s a masterful, disarming quality, and exactly what Voldemort needs.

The idea that you don’t recognize the threat until it’s too late fits a Dark Lord who gains power through cleverness and control, not just flashy displays. Thomas would portray Voldemort as a truly frightening thinker – calm, convincing, and completely devoted to her beliefs. She’d make intelligence itself seem menacing, and that’s when Voldemort is most effective.

Gary Oldman

Gary Oldman is consistently one of the most adaptable actors in the industry. He’s known for seamlessly transitioning between diverse roles, from the dependable James Gordon in the Dark Knight films to his Academy Award-winning portrayal of Winston Churchill in Darkest Hour, and even his early, raw performance as Sid Vicious in Sid and Nancy.

He was once known for playing Sirius Black in the Harry Potter films, but his part was smaller than in the books. This might be why people don’t often mention him when talking about who could have played Voldemort.

When Gary Oldman fully embraces dramatic, unpredictable, and commanding performances, like in Bram Stoker’s Dracula and Léon: The Professional, he captures a core element of the Tom Riddle character.

David Tennant

David Tennant has proven he can play convincingly sinister and captivating villains – qualities essential for the role of Lord Voldemort. While he’s famous for his friendly and clever portrayal of the Tenth Doctor in Doctor Who and his realistic intensity as DI Alec Hardy in Broadchurch, he completely transformed his image to play the chilling Kilgrave in Jessica Jones.

Kilgrave’s power to control people is similar to Voldemort’s – he forces others to do his bidding, uncaring of the damage he causes. David Tennant previously played Barty Crouch Jr. in Harry Potter and the Goblet of Fire, but that role was short enough that audiences wouldn’t be confused if he took on another part.

As a huge movie fan, I’ve always been impressed by David Tennant’s ability to play characters who are both charming and genuinely scary – it’s a really delicate balance, and he nails it every time, especially when you think about iconic villains. Honestly, I’m a little surprised he’s not mentioned more often when people talk about dream casting for big roles!

James McAvoy

James McAvoy consistently delivers compelling performances, blending charm, intelligence, and deep emotion – qualities that would actually make him a surprisingly good choice to play Voldemort. While he’s famous for his role as the young Professor X in the X-Men films, that role really highlights his talent for portraying a character who is both intellectually powerful, intensely focused, and morally complex – someone who could easily walk the line between good and ruthlessness.

James McAvoy brings similar qualities to his role as Lord Asriel in His Dark Materials. He’s both captivating and intimidating, driven by a strong and unwavering belief. And, as seen in Split, McAvoy has an incredible ability to play complex characters, even showcasing a frighteningly convincing portrayal of multiple personalities.

James McAvoy’s ability to play a wide range of roles, combined with his naturally compelling presence, makes him a strong fit for the role of Voldemort. Considering his acting background, it’s surprising he isn’t getting more attention as a potential cast member for the upcoming Harry Potter TV series.
