HBO has released the first teaser trailer for its upcoming Harry Potter television series, announcing a premiere date of Christmas 2026. The series, based on J.K. Rowling's best-selling books, will debut with an adaptation of Harry Potter and the Philosopher's Stone.
The two-minute trailer introduces the three central characters: Harry Potter (Dominic McLaughlin), Hermione Granger (Arabella Stanton) and Ron Weasley (Alastair Stout), who meet as 11-year-olds on the Hogwarts Express. It also teases iconic moments such as Harry's meeting with Hagrid (Nick Frost), the Sorting Hat ceremony and his first Quidditch match.
The cast includes John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall and Paapa Essiedu as Severus Snape. Francesca Gardiner serves as showrunner, with Mark Mylod directing several episodes. The series is produced at Leavesden Studios in Hertfordshire.
Warner Bros Discovery's JB Perrette described the series as 'the biggest streaming event in the history of HBO Max and arguably in streaming, period'. The show aims to delve deeper into the books than the eight-film franchise.
Original star Daniel Radcliffe praised McLaughlin, saying he is 'going to be better than me'. Meanwhile, Essiedu revealed he has received death threats over his casting as Snape, but said he uses the backlash to 'fuel' his performance. Rowling's anti-trans comments have also drawn criticism, but HBO's Casey Bloys defended her involvement, stating the series is not 'infused with anything' from her personal views.
