The New Harry Potter TV Show Trailer Is Spellbinding
Welcome back to Hogwarts!
Hogwarts is ready to open up to a new generation of witches and wizards. A television adaptation of J. K. Rowling’s fantasy saga is coming to HBO, with a whole new cast reimagining the beloved magical characters. As you prepare to run back into Platform 9¾, here are all the details about when the new Harry Potter series will arrive, and who is going to be taking on the iconic roles.
HBO announced the new Harry Potter show back in 2021. In the years since, the team behind the project set out on an expansive search to cast the three new stars, all while the adaptation has faced controversy due to Rowling’s involvment as an executive producer. Finally, in the summer of 2025, HBO confirmed that production had begun on the massive new TV show. And now, the network has confirmed exactly when fans will be jumping back into the wizarding world.
While you wait for your next visit to Hogwarts, here are all the magical updates about the upcoming series, including the new star who will be this generation’s Harry Potter.
The Cast Is A Mix Of Unknowns & Superstars
As with the 2000s Harry Potter movies, the series opted to cast previously unknown child actors in the lead roles. Dominic McLaughlin will play Harry Potter, with Alastair Stout as Ron Weasley, and Arabella Stanton as Hermione Granger. When production on the series began on July 14, 2025, HBO shared a first look at McLaughlin in his Hogwarts uniform.
The adult cast is full of more established A-listers, like John Lithgow, who is playing Albus Dumbledore, and I May Destroy You breakout Paapa Essiedu as Severus Snape. Janet McTeer is also on Hogwarts’ faculty as Minerva McGonagall, with Nick Frost rounding out the main cast as groundskeeper Rubeus Hagrid.
The Trailer Is Spellbinding
HBO finally gave fans a first glimpse at the new generation of Hogwarts in the show’s first trailer on March 25. There are only quick peeks into the wizarding world, though, as the clip mainly focuses on Harry Potter’s origin story in the Muggle realm.
The Premiere Date Is Appropriately Festive
The trailer also revealed that the new series will premiere on HBO on Christmas 2026.
