Harry Potter: Ralph Fiennes Reveals Why He Won't Return As HBO's Voldemort And Endorses Surprising Actress

Ralph Fiennes played Voldemort in the Harry Potter movies, and reveals why he's closed the door on a possible return for the upcoming TV series on HBO Max while endorsing Tilda Swinton.

Harry Potter and the Philosopher's Stone will premiere on HBO Max this Christmas, and following a well-received teaser trailer, excitement for this small-screen reboot of the Wizarding World is rapidly building. 

While the main cast has now been revealed, the streaming platform is keeping Voldemort under wraps. All puns aside, the villain will, of course, be literally under wraps in the show's first season as he currently resides on the back of Professor Quirrell's head. 

Fans are expecting to learn who will play Voldemort before Harry Potter premieres, with their voice and likeness used for both his possession of Quirrell and a flashback to the night James and Lily Potter were murdered

Ralph Fiennes didn't start playing Voldemort until the fourth movie, 2004's Harry Potter and the Goblin of Fire. HBO could similarly make us wait before casting the villain, but it doesn't seem likely.

During an appearance on The Claudia Winkleman Show (via SFFGazette.com), the actor said that, despite previously being open to reprising the role, he now feels that the moment has passed.

"I remember being asked the question once we’d shot the total film series, would I reprise the part, and this was some years ago. I said, 'Yes, I’d love to,'" Fiennes revealed. "But then nothing’s happened, and I think that ship has sailed."

"But I’ll tell you, Tilda Swinton was mentioned somewhere as being a contender, and I think she would be amazing," The Hunger Games: The Sunrise On The Reaping star added, giving his seal of approval to the Doctor Strange actress.

There have been online rumours about a female Voldemort, and Fiennes previously gave his seal of approval to his 28 Years Later: The Bone Temple co-star, Cillian Murphy. He's since denied having any involvement, meaning we're in the dark about who will ultimately play He-Who-Must-Not-Be-Named. 

Harry Potter and the Philosopher's Stone hasn't really attracted any A-list film stars, so it remains to be seen whether HBO Max will look to cast a huge name or an actor who is perhaps less well-known but still a good fit for the monster previously known as Tom Riddle.

It's worth noting that the latest rumours have pointed to WandaVision and Solo: A Star Wars Story star Paul Bettany playing Voldemort. 

There is nothing special about Harry Potter - at least that's what his Aunt Petunia always says. On his 11th birthday, a letter of admittance to Hogwarts School of Witchcraft and Wizardry opens up a hidden world for Harry: one of fun, friendship and magic. But with this new adventure comes great risk as Harry is forced to face a dangerous enemy from his past.

The main cast of Harry Potter and the Philosopher's Stone includes Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, Alastair Stout as Ron Weasley, John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Rory Wilmot as Neville Longbottom, and Lox Pratt as Draco Malfoy.

Additional cast includes Daniel Rigby as Vernon Dursley, Bel Powley as Petunia Dursley, Paul Whitehouse as Argus Filch, Luke Thallon as Quirinus Quirrell, Katherine Parkinson as Molly Weasley, Amos Kitson as Dudley Dursley, Gracie Cochrane as Ginny Weasley, Leigh Gill as Griphook, and Anton Lesser as Garrick Ollivander.

The series, based on J.K. Rowling’s beloved books, is written and executive-produced by Francesca Gardiner. Mark Mylod will executive produce and direct multiple episodes of the series for HBO in association with Brontë Film and TV and Warner Bros. Television. The series is executive produced by J.K. Rowling, Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV, and David Heyman of Heyday Films.

Harry Potter and the Philosopher's Stone premieres on HBO Max this Christmas.

Rather than getting into the denial game, he's being a total luvvie and endorsing anyone who gets mentioned.

Quite refreshing actually...

@Biggums - one step away from "oh, I couldn't *possibly* do it luvvie!" Which is luvvie-speak for "I'd love my old job back... for a price."

I love that I guessed Tilda before reading part of the article. Mostly because her character, Ancient One, in Doctor Strange, was on my mind (my “hear me out” 😈)

I can see why he’d be open to “returning to the role” because the character and his portrayal are both iconic and I’m sure he’s fun to play, but I’m not sure why he’d want to just replay the same stories again.

An award winning performer who is one of the most Voldemort looking people alive. I have no doubts Swinton could rock the role.

The meltdown people would have would be more entertaining than the show

@Wahhvacado - wether someone could rock it vs wether it’s necessary are two different things. I don’t really care about potter but I don’t understand this new craze of trying to ragebait fans. Like why not just make the character appear as they were written? I don’t think there’s really any practical or narrative advantage / application to changing it, so as far as I can tell it would just be pointless? Not trying to argue just genuinely want your opinion

@allwalledup - Why would Tilda Swinton not be "As they were written"?

@ObserverIO - umm, cuz isn’t Voldemort supposed to be a dude? “He who shall not be named” right?
ObserverIO

@allwalledup - Just because they're casting a female actor doesn't mean they automatically have to make the character female too. Actors act. She can play a dude.

allwalledup - 4/16/2026, 9:35 PM
@ObserverIO - personally, I never really bought that. I think that’s more applicable to voice acting than live action where the physical appearance matters. Why not just get someone who’s actually a dude so it’s closer to the authentic character? You wouldn’t throw a white person in black face if you wanted to cast a black role, you’d just cast a black person. So how’s this any different? Genuinely asking, if it CAN be done authentically, then why not just do it as authentically to the original version of the character as possible? I don’t see any reason they need to cast a woman as Voldemort when Voldemort is in fact a man.
ObserverIO
ObserverIO - 4/16/2026, 9:44 PM
@allwalledup - She's quite androgynous. Eventually we'd just believe she's a man. We'd see the character not the actor like we do with most good performances.

But even if she looked like Sydney Sweeney, we could still suspend our disbelief for the make-believe.

Also with this particular character there's so many practical and visual effects involved in their appearance it may as well be voice over.
allwalledup
allwalledup - 4/20/2026, 3:56 PM
@ObserverIO - that’s a fair point, I guess along with prosthetics make up and her acting skills it could be done in a convincing way. If they lowered the pitch of her voice like they do with Robert England’s Freddy to give it a more threatening aura would be cool.

Well-received teaser? Goblin of Fire?
What the heck is going on? Another Mandela Effect moment?

Swinton is one of those performers that nail character roles so well, that I'm sure she'd nail Voldemort.

Although, I'd be more down for her to take on Belatrix.

No issues with Tilda whatsoever. She's a walking, breathing, living example of uncanny androgyny.

My only requirement would be that she play it strictly as a male persona. 🤓

Tilda Swinton would be interesting though if there’s any HP role I would want to see her play , It’s Bellatrix tbh…

Also I love Ralph Fiennes as an actor & Voldemort but to me he’ll always be the enemy of Daniel Radcliffe’s Harry so I would rather Dominic McLaughlin have his own.

My pick is still Matthew Goode since he can be charismatic & sinister imo!!.

Goblin of Fire must have come somewhere between Goblet of Fire and Order of the Phoenix.
