Since the first novel released in 1997, the interest in Harry Potter has never really gone away. The Wizarding World is a cultural phenomenon, and undeniably one of the world's biggest entertainment franchises. Despite already being adapted into eight excellent movies, the series will return to our screens later this year with an all new, serialized adaptation at HBO—a series that'll continue to be on our screens for around a decade.
Of course, the HBO adaptation has been shrouded in controversy; look no further than J.K. Rowling, who's often in the media for reasons that aren't positive. Plus, we already have movie adaptations, which begs the question: do we really need a series? Even so, the show is happening, whether we like it or not. And the benefit of it being a TV series means adapting the novels in full with more time and scope to tell stories that couldn't be covered in the constraints of a movie.
Harry Potter keeps getting more popular
Even though it's not airing until December, the HBO series is already sparking great interest in the novels, not least thanks to the release of the official teaser trailer in March 2026. According to a report from language-learning app Preply (via PEOPLE), interest in the original novels has shot up by 156% in the last month. In addition to this, fans are spending more time searching up the original movies, with an increase of 122%.
With Preply being a language-learning platform, their linguistic expert Cristina Miguelez spoke about the jargon used within the Harry Potter franchise, from slang to magical terminology. “The invented terms in Harry Potter help create a shared language among fans and give the story a distinct identity," she said. “Spells and magical terms sit comfortably alongside everyday British dialogue, making the world feel both familiar and new."
In the months leading up the release of HBO's Harry Potter, we expect to see reader interest intensify. The series already has an enormous dedicated audience, but whether it's able to sustain viewership across its massive, decade-long plan remains to be seen.
The main cast of the forthcoming Harry Potter series includes Dominic McLaughlin as Harry Potter, Alastair Stout as Ron Weasley and Arabella Stanton as Hermione Granger. Also involved is John Lithgow as Dumbledore, Paapa Essiedu as Professor Snape, Nick Frost as Hagrid, and Janet McTeer as Professor McGonagall.
HBO's Harry Potter season 1, subtitled Harry Potter and the Philosopher's Stone, launches on Christmas Day 2026.
