New Stars Revealed For HBO’s Harry Potter Reboot

Announced last spring, the Harry Potter reboot will bring J. K. Rowling’s beloved wizard novels back to the screen – this time, the small screen. That’s right: it’s not a sequel nor a prequel, but reportedly a ‘faithful’ adaptation of Rowling’s original seven novels crafted by an all-star team at HBO. And we finally know who will star. Here’s what you need to know.

What’s The Story With The Harry Potter TV Reboot?

The idea with a Harry Potter TV reboot has been toyed with since 2019, with various prequels and sequels for the small screen discussed – but eventually ditched. Flash forward to 2021, David Zaslav became the new CEO of Warner Bros and travelled to London to meet author J.K. Rowling to discuss possible TV shows in her universe. It wasn’t until March 2023, however, that things really started moving: Warner Bros closed a deal with Rowling for an adaptation, with the author playing a part in creative development. In April of the same year, the reboot idea was confirmed: the TV series won’t be anything new, but instead a faithful adaptation of Rowling’s original seven books, with seven 10-episode seasons beginning with the first in late 2026 or early 2027. Full steam ahead!

In September 2024, however, it became clear that casting still hadn’t happened, with a call-out for Harry, Ron and Hermione floating through the media world. Jump slightly ahead again to October, and it seemed more progress was being made – but how true is it?
