After months of speculation and behind-the-scenes photos, HBO has finally unveiled the first footage of its Harry Potter television series. The series is scheduled to premiere on HBO on December 25, 2026, with the first season consisting of eight episodes. The trailer's release marks a turning point for the franchise: no longer just film adaptations, but a full-scale television reimagining.
The first season is officially titled 'Harry Potter and the Philosopher's Stone', taking the original book's UK title rather than its American counterpart. The trailer opens with Harry living in his cupboard room under the stairs at the Dursleys' home, bullied by his cousin Dudley and receiving a painful haircut from Aunt Petunia, who tells him he's not special until he gets his acceptance letter to Hogwarts. Never-before-seen moments from the stories will be brought to life on screen for the first time, starting with Harry's time at Muggle school.
The casting represents a generational shift. Dominic McLaughlin will play Harry Potter, Arabella Stanton will play Hermione Granger, and Alastair Stout will play Ron Weasley. The three are largely newcomers, with McLaughlin acting in 'Grow', a comedy on Sky, Stanton starring as Matilda in the musical of the same name in the West End, and Stout having no prior acting credits. Rather than casting recognisable faces, HBO appears to be betting on fresh talent to make these roles their own.
The supporting cast leans toward established names. John Lithgow entered final negotiations to portray Dumbledore and was confirmed in April 2025, while Janet McTeer and Nick Frost entered negotiations to play McGonagall and Hagrid and were confirmed alongside Paapa Essiedu as Snape. Lox Pratt plays Draco Malfoy, with brief appearances from John Lithgow's Albus Dumbledore, Paapa Essiedu's Severus Snape, and Janet McTeer as Minerva McGonagall.
The series itself represents something broader: a long-form television commitment. The series is structured as a faithful retelling of J.K. Rowling's novels, with each season adapting one book from the seven-part saga. Succession writer Francesca Gardiner serves as showrunner and executive producer, while Mark Mylod will direct multiple episodes in addition to serving as executive producer. Filmed at Warner Bros. Studios Leavesden in the U.K., the series is led by showrunner Francesca Gardiner, with "Succession" director Mark Mylod taking on multiple episodes.
As a faithful adaptation of the books, the show is packed with 90s nostalgia, from outfit choices and hairstyles of the Muggles on the London Underground to Mrs. Weasley's ensemble making her the epitome of the 90s mum. The series will offer insight into the personal lives of both teachers and the Draco family, providing a perspective wider than the books which are very much over Harry's shoulder.
The Christmas 2026 premiere date is earlier than the 2027 date that had been previously announced. Filming for the first season is expected to last until mid-2026, with production on the second season set to begin a few months thereafter. In November 2025, HBO reaffirmed its intention to film these seasons back-to-back.
For longtime fans, this remake carries both promise and risk. The original 2001-2011 film series defined a generation's experience of the books. A decade-long television adaptation offers the opportunity for nuance and detail that film cannot provide. Whether audiences embrace a Dumbledore who isn't Richard Harris or Michael Gambon, or a Hagrid played by Nick Frost rather than Robbie Coltrane, remains to be seen. Daniel Radcliffe has expressed his support for the up-and-comers, saying he does not want to be a specter in the life of the new cast. That goodwill may matter as viewers prepare to step back into the Wizarding World on Christmas Day.
