Fans of the wizarding world have reason to celebrate: HBO has officially unveiled the first trailer and release date for its highly anticipated new series, Harry Potter and the Philosopher’s Stone. The announcement, made on March 25, 2026, during a star-studded event in London, marks the beginning of a bold new era for J.K. Rowling’s beloved saga, now reimagined as a multi-season dramatic series for television. The show is set to debut globally on HBO and HBO Max on Christmas Day, December 25, 2026, promising a magical holiday for viewers around the world.
The fresh adaptation is a direct, faithful retelling of Rowling’s original books, starting with the story that first introduced readers to The Boy Who Lived. The official logline teases: “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.” According to Deadline, the trailer captures many of the saga’s most iconic moments, including Harry’s life under the stairs, his bullying at the hands of cousin Dudley, and the fateful arrival of his Hogwarts letter.
Stepping into the legendary role of Harry Potter is newcomer Dominic McLaughlin, whose first appearance in Gryffindor robes was teased on HBO’s official Instagram just a day before the trailer’s release. Joining him are Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley, forming the new trio at the heart of the story. Other major cast members include John Lithgow as Albus Dumbledore, Janet McTeer as Professor Minerva McGonagall, Nick Frost as Rubeus Hagrid, and Paapa Essiedu as Professor Severus Snape. The supporting cast is rounded out by Luke Thallon as Professor Quirrell, Lox Pratt as Draco Malfoy, Johnny Flynn as Lucius Malfoy, Katherine Parkinson as Molly Weasley, and many others, making for an impressively expansive ensemble.
According to The Hollywood Reporter, the new series is being helmed by Francesca Gardiner, best known for her work on Succession, who serves as both showrunner and writer. Mark Mylod, another Succession alum, will direct multiple episodes and executive produce alongside Gardiner. J.K. Rowling herself is closely involved as an executive producer, joined by Neil Blair, Ruth Kenley-Letts of Brontë Film and TV, and David Heyman of Heyday Films—the latter having produced the original film series.
The trailer, which premiered to an audience in a room designed to mimic Harry’s cupboard under the stairs, offers glimpses of beloved characters and magical moments. Fans are treated to scenes of Harry being bullied at the Dursley home, receiving his Hogwarts letter, meeting Hagrid for the first time, and traveling on the Hogwarts Express. The trailer also features Ollivander, the wand maker, telling Harry, “Mr. Potter, I think we can expect great things from you,” and Hagrid reassuring the young wizard, “Your parents were the bravest, kindest people I’ve ever met … they stood up for what they think is right. … Next time I see you will be in Hogwarts.”
The series has not been without controversy. Paapa Essiedu’s casting as Severus Snape, a character originally described as pale and previously portrayed by Alan Rickman, has sparked backlash in some quarters of the fandom. Essiedu revealed to The Times that he has received death threats and racist abuse since the casting was announced. “I’ve been told, ‘Quit or I’ll murder you,’” he shared. “It really matters. The reality is that if I look at Instagram, I will see somebody saying, ‘I’m going to come to your house and kill you.’ While I hope I’ll be okay, nobody should have to encounter this for doing their job. Many people put their lives on the line in their work. I’m playing a wizard in Harry Potter. And I’d be lying if I said it doesn’t affect me emotionally. The themes that run through Harry Potter are of love triumphing over hate — of acceptance. And that’s why I’m doing it.”
HBO Chairman Casey Bloys addressed the issue directly, telling Deadline, “We talked to them about what to expect ... but any kind of security that’s needed is an unfortunate aspect of doing IP shows. We just try to be mindful and monitor it.” This is not the first time a casting decision in the Potter universe has ignited debate; a decade ago, Noma Dumezweni faced similar backlash when cast as Hermione Granger in the West End production of Harry Potter and the Cursed Child.
John Lithgow, who plays Dumbledore, has also faced criticism, but for a different reason—his involvement in a project associated with Rowling, who remains a polarizing figure due to her views on trans rights. Lithgow told The Hollywood Reporter he’s been “stung” by the criticism, but emphasized that Rowling’s books are “clearly on the side of the angels, against intolerance and bigotry.” HBO boss Casey Bloys has reiterated that Rowling’s personal views are her own and that the series itself is not “secretly being infused with anything.”
Musically, the series will feature a new score composed by Hans Zimmer and Bleeding Fingers Music, adding another layer of freshness to the reboot. According to Los Angeles Times, the show aims to introduce the Harry Potter franchise to a new generation, with a cast of relative newcomers taking on the iconic roles. The creative team has stressed their commitment to a “faithful adaptation” of the original books, a promise that has been met with both excitement and scrutiny from longtime fans.
Anticipation for the series is sky-high. JB Perrette, CEO and president of global streaming and games at Warner Bros. Discovery, described HBO’s Harry Potter as “the biggest streaming event in the history of HBO Max and arguably in streaming, period. It’s number one, two and three in many ways.” The decision to use the original UK title, Harry Potter and the Philosopher’s Stone, rather than the Americanized Sorcerer’s Stone, is another nod to authenticity that has delighted many purists.
Even Daniel Radcliffe, who first brought Harry Potter to life on screen, weighed in on the new series. “I’m sure Dominic is going to be better than me,” Radcliffe told reporters. “I learned as I went. I look back on what I did now with a lot more kindness, and I find it less embarrassing now that I’m older. But I was very much learning how to do it for a long time on Potter.”
As the countdown to Christmas Day 2026 begins, the wizarding world is abuzz with speculation, nostalgia, and excitement. With a new cast, a fresh creative team, and a promise of faithfulness to the original books, HBO’s Harry Potter and the Philosopher’s Stone looks set to enchant a whole new generation—while giving longtime fans plenty to talk about around the holiday table.
