HBO released a new full-length trailer for its “Harry Potter” television adaptation on Wednesday, offering the fullest look yet at the young cast inside Hogwarts ahead of the show’s Christmas Day premiere.
The footage, unveiled during a “Back to Hogwarts Day” livestream, shows Harry sorted by the enchanted Sorting Hat, squaring off against Professor Snape and preparing for his first Quidditch match. HBO paired the trailer with an updated synopsis describing an ordinary boy who learns of his hidden magical heritage through a Hogwarts acceptance letter, only to confront a dangerous enemy from his past once inside the castle walls.
Newcomer Dominic McLaughlin stars as Harry, with Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley. John Lithgow plays Albus Dumbledore, Janet McTeer takes on Minerva McGonagall, Paapa Essiedu portrays Severus Snape and Nick Frost appears as Rubeus Hagrid.
The series, adapting J.K. Rowling’s seven novels across as many seasons, follows an earlier teaser in the spring that drew criticism from some fans over its visually darker tone compared with the original film franchise. A subsequent behind-the-scenes special showed full-scale sets built for locations including Diagon Alley and the Great Hall, work the production team said was intended to preserve the books’ sense of wonder rather than lean entirely on digital effects.
Season two, adapting “Harry Potter and the Chamber of Secrets,” has already received an early renewal and begins filming this fall, with Jon Brown elevated to co-showrunner alongside Francesca Gardiner. That season underwent a late casting change after Nicholas Hoult exited his role as the vain professor Gilderoy Lockhart because of scheduling conflicts tied to other film commitments.
Kit Harington, who previously voiced the character in an Audible audio adaptation, stepped into the part instead. Production has framed the swap as routine, though the announcement arrived amid continued scrutiny of the franchise’s ties to Rowling, who serves as an executive producer and has faced backlash over her public statements on transgender issues.
Season one, titled “Harry Potter and the Philosopher’s Stone,” premieres on HBO and HBO Max on Dec. 25.
