Ralph Fiennes, the legendary actor known for his portrayal of Voldemort, recently offered lighthearted yet practical guidance for whoever inherits the dark wizard’s role in HBO’s highly anticipated Harry Potter reboot. As excitement grows for the new series, Fiennes’ advice gives fans a fresh look at what it takes to embody one of fiction’s most formidable villains—while putting the spotlight on wardrobe challenges the next Voldemort must face.
Fiennes Opens Up About Portraying Voldemort and His Unique Advice
The Harry Potter universe, since its debut in 1997, has become one of the most influential franchises worldwide. With HBO developing a reboot series, fan reactions have ranged from eager anticipation to hesitation, fearing that nothing can match the original films. Nevertheless, actors like Ralph Fiennes appear to support the next generation stepping into these celebrated roles.
Known for acclaimed performances in “Red Dragon,” “The Constant Gardener,” “The Menu,” and “Conclave,” Fiennes first assumed the persona of Lord Voldemort in 2005’s “Goblet of Fire.” Prior to Fiennes, the infamous villain briefly appeared as portrayed by Ian Hart and Richard Bremmer in “Philosopher’s Stone.” However, Fiennes’ chilling depiction across four movies left a lasting impact, making the position a tall order for any successor.
Wardrobe Challenges for the Next Voldemort Performer
In a recent interview with Entertainment Tonight on TikTok, Ralph Fiennes was asked if he had pointers for the actor soon to wield Voldemort’s wand. He slyly remarked:

“My advice is make sure you can handle the long, flowing robes and don’t trip over them,”
—Ralph Fiennes, Actor
With his signature poise, he added:
“Practice your long, flowing robe walk.”
—Ralph Fiennes, Actor
Reflecting on his time as the dark wizard, Fiennes recalled wearing tights beneath a one-piece suit and wrestling with a gusset that grew increasingly awkward as filming dragged on. While Fiennes has expressed interest in reprising the role—and Hero Fiennes-Tiffin has also shown enthusiasm—HBO appears committed to a new cast for this television retelling.
The Legacy and Transformation of Voldemort in the Franchise
Within the wizarding world, Voldemort—an anagram of Tom Marvolo Riddle—remains the story’s central villain, serving as the architect of Harry’s tragic past and that iconic lightning-shaped scar. Although Rowling’s original vision included some fearsome forms never brought to life on screen, Fiennes’ noseless incarnation became a definitive pop culture image, feared and revered by fans across the globe.
Meet the Cast Set to Continue the Harry Potter Tradition
HBO has begun assembling its spellbinding ensemble, with several key roles already filled by emerging talent. Dominic McLaughlin will play Harry Potter, Arabella Stanton appears as Hermione Granger, and Alastair Stout steps in as Ron Weasley, ensuring the famous trio’s legacy continues. Janet McTeer will take on Professor McGonagall, and Paapa Essiedu is cast as Severus Snape, offering fresh interpretations of characters originally shaped by Dame Maggie Smith and Alan Rickman. John Lithgow has accepted the role of Albus Dumbledore, adding a new dimension to Hogwarts’ esteemed headmaster. Nick Frost is set to portray Hagrid, beloved friend and gamekeeper.
Why the Timing Feels Right for a Harry Potter Revival
Actor Gary Oldman, who portrayed Sirius Black in the original films, weighed in on why this moment is ideal for reimagining the franchise. He noted that, with the assembled cast and modern storytelling possibilities, the reboot provides opportunities for both seasoned actors and newcomers to make their mark on the magical saga.
What Lies Ahead for the Harry Potter Reboot Series
Scheduled to premiere in late 2026 or early 2027, HBO’s adaptation has inspired both nostalgia and curiosity within the fanbase. As the franchise welcomes new faces, the impact of Ralph Fiennes’ take on Voldemort, and his playful yet practical advice, endures as a reminder that even darkest wizards must tackle humble challenges—like mastering their long, billowing robes. The fresh cast and creative team have the daunting task of living up to legacy performances, but with the franchise’s history of memorable quotes and moments, fans can expect plenty more magic—and mischief—to come.
