‘Harry Potter’ trailer finally drops as fans are torn over HBO reboot

HBO has finally dropped the first teaser and trailer for its Harry Potter reboot, giving fans their biggest look yet at the Wizarding World ahead of its December 2026 release.

The series will begin with Harry Potter and the Philosopher’s Stone, adapting J.K. Rowling’s first book as part of a long-form, multi-season retelling.

First look at Hogwarts and key characters

The trailer revisits Harry’s early life at the Dursleys’ home, showing him living under the stairs before receiving his Hogwarts letter and stepping into the magical world.

It also offers glimpses of key moments including his meeting with Hagrid, his journey on the Hogwarts Express and his first look at Hogwarts itself.

Several major characters are introduced, including new versions of Dumbledore, Snape, McGonagall and Draco Malfoy, alongside Harry, Ron and Hermione.

The footage leans into a more detailed and book-faithful approach, expanding on moments that were only briefly shown in the original films, including Harry’s time at Muggle school and smaller character-driven scenes.

How the HBO reboot compares to the original films

While the scale and detail have impressed many, comparisons to the original Harry Potter films have quickly taken over the conversation.

Fans have pointed out that the reboot feels both familiar and slightly different, with one viewer describing it as “like one of those parallel universes where everything is the same, but slightly off.”

The series appears to follow the books more closely than the films, using its extended format to explore moments and characters in greater depth.

However, the original films remain deeply tied to audiences who grew up with them, making any reboot a difficult balance between nostalgia and reinvention.

Fan reactions split over casting and tone

Online reactions to the trailer have been sharply divided.

Some fans praised the increased accuracy to the books, with one joking the show already looks “so book accurate” based on early character reveals.

Others questioned casting choices and new interpretations of iconic roles, particularly around visual changes to familiar characters.

There were also lighter reactions, with fans joking about details like Hagrid’s voice and referencing iconic lines from the original films.

One widely liked comment read: “As long as Dumbledore says calmly ‘Harry, did you put your name in the Goblet of Fire’, it will be a wonderful series.”

Another fan summed up the mood more bluntly: “It’s like reading the book in a different font.”

Release date and what to expect

The first season of Harry Potter will premiere in December 2026 and will consist of eight episodes.

The show is currently in production at Warner Bros. Studios Leavesden in the UK, with Francesca Gardiner serving as showrunner and Mark Mylod directing multiple episodes.

Rowling is attached as an executive producer alongside longtime franchise producer David Heyman.

With the trailer now released, HBO’s reboot is already one of the most talked-about upcoming series, with fans split between excitement and scepticism as they wait to see how it measures up to the original films.
