The new Harry Potter HBO trailer offers a longer look at Harry Potter and the Philosopher’s Stone, offering a longer look at the eight-episode series before its Christmas 2026 debut. The trailer includes the Sorting Hat ceremony, the first Quidditch match, the bathroom troll and a young Harry learning that Hogwarts is not short of surprises.
The footage introduces Dominic McLaughlin as Harry Potter, alongside Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley. It also gives viewers more of Paapa Essiedu as Severus Snape, John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall and Nick Frost as Rubeus Hagrid.
Harry Potter HBO trailer revisits familiar Hogwarts moments
The trailer moves through several recognisable scenes from the first book, including Harry’s sorting into Gryffindor, the trio’s early friendship, Ron receiving his Hogwarts letter and Harry using the Cloak of Invisibility. The Mirror of Erised and a Quidditch match also appear, while Snape remains unimpressed with his new pupil.
It includes brief shots that appear to show Lily and James Potter in a flashback. There is also what may be an early glimpse of Lord Voldemort, although the footage does not identify the figure directly.
Watch the official HBO trailer
The official trailer runs for 2 minutes and 37 seconds and is available on the Harry Potter YouTube channel. IGN’s trailer breakdown lists the major scenes and cast appearances shown in the footage.
The series is written and executive produced by Francesca Gardiner. HBO has confirmed a Christmas 2026 debut, but a specific date and regional streaming details have not been announced in the sources checked for this report. Variety has also reported that Warner Bros. Discovery is planning a wider 2026 Back to Hogwarts celebration around the 25th anniversary of the original film.
The new series follows earlier casting news, including Sirine Saba as Professor Sprout, and Season 2 of Harry Potter begins filming in the fall with Kit Harrington taking on the role of the Defense Against the Dark Arts teacher Gilderoy Lockhart (replacing Nicholas Hoult). For now, the trailer is doing the usual job: showing just enough Hogwarts to make December feel further away than it is.
