After seven core-series books, 11 films including three Fantastic Beasts prequels, a stage sequel, and countless spinoffs and inspirations in the form of theme parks, video games, merchandise, and more, the Wizarding World is set to soon expand to one more medium: TV.
Warner Bros. Discovery announced plans in 2023 to develop a new live-action Harry Potter series, with each book in the main franchise to be adapted into one of seven seasons that will come out over 10 years on cable network HBO and its streaming platform HBO Max.
“I’m looking forward to being part of this new adaptation which will allow for a degree of depth and detail only afforded by a long form television series,” said J.K. Rowling, who authored the novels that first published in 1997 and who will be an executive producer of the series.
“The series will feature a new cast to lead a new generation of fandom, full of the fantastic detail, much loved characters and dramatic locations that Harry Potter fans have loved for over twenty-five years,” Warner Bros. Discovery said in its announcement.
The original movies launched the careers of stars like Daniel Radcliffe and Emma Watson, while also featuring beloved actors such as Alan Rickman, Helena Bonham Carter, and Ralph Fiennes.
With the first season of the reboot expected to be released in late 2026 or early 2027, Warner Bros. Discovery has steadily revealed more and more of the names set to take part, most recently announcing nine roles on June 9.
Here’s everyone we know so far that will be in the new Harry Potter series.
