LOS ANGELES, CALIFORNIA: Rumors began swirling across the internet claiming that Daniel Radcliffe—best known for portraying the Boy Who Lived—would be returning to the Wizarding World as Lord Voldemort in HBO’s highly anticipated reboot.
According to the viral reports, Radcliffe was slated to play the adult Dark Lord opposite newcomer Dominic McLaughlin, who has been cast as the new Harry Potter. Let’s take a closer look at the validity of this report.

The speculation gained traction after a post on X (formerly Twitter) by an account named DiscussingFlow claimed to share an exclusive casting update for the HBO series.
The post asserted that Radcliffe would step into the shoes of He-Who-Must-Not-Be-Named to oppose his own successor, attributing the false news to industry outlet Variety.
Within a short span, the tweet amassed over 744,000 views, leaving many fans puzzled and eager to find out if the shocking casting choice was authentic. Numerous users turned to AI tools like Grok or posted online to verify the news.
You either die a hero, or you live long enough to see yourself cast as Lord Voldemort.
Daniel Radcliffe playing the Dark Lord in the HBO reboot wouldn’t just break the internet, it would be the single greatest passing of the baton moment in pop culture history. Do it, HBO. https://t.co/nPiFzkQERZ
The internet reacted with a mix of disbelief, humor, and excitement. One user joked about the poetic irony of the original hero transforming into the ultimate villain, calling on HBO to make the hypothetical casting a reality for the sake of pop culture history.
Another commenter noted that while they hadn’t planned on watching the reboot, seeing Radcliffe play the antagonist would certainly win them over.
Fact Check: The Casting Claim is Entirely False

To clear up any confusion: Daniel Radcliffe is not involved in the HBO Harry Potter series as Lord Voldemort. While Dominic McLaughlin has indeed been attached to lead the project as Harry Potter, network executives have not yet cast an actor to portray the adult version of Voldemort.
For the adaptation’s second season—which will cover Harry Potter and the Chamber of Secrets—HBO previously announced that Billy Barratt will play the younger Tom Riddle. However, the older incarnation of the character remains uncast.
While various high-profile names, such as Paul Bettany and Cillian Murphy (who has already debunked his involvement), have frequently surfaced in fan theories and media rumors, Radcliffe’s name has never been officially associated with the role.
Furthermore, Radcliffe has consistently maintained that the upcoming adaptation should offer a completely fresh and clean break from the original film adaptations, signaling no personal desire to return to the franchise in a new capacity.
Ultimately, the viral post originated from a parody-style account leveraging the ironic concept of the original franchise star taking on the role of his former nemesis, and it holds no truth.
