In January, Warner Bros TV chairman Channing Dungey spoke about the importance of finding the right team to lead the show.

She said: "We're in conversations with a number of different writers to figure out who's going to be the person to lead that franchise for us."

She added: "The first step for us is figuring out who this showrunner is going to be and once we get that locked down, then we can start having those [casting] conversations."

There are no casting details available thus far, although Dungey admitted the "first two books" were the most challenging.

She explained: "The tricky part is the first two books, where the kids are on the younger end, around 11 or 12."

The show will release over a decade, with each season based on one of the seven books, and Warner Bros Dicovery CEO David Zaslav previously said the first is expected to drop in 2026.

The studio's logline reads: "The series will be a faithful adaptation of the beloved 'Harry Potter' book series by author and ex ecutive producer J.K. Rowling.

"The series will feature a new cast to lead a new generation of fandom, full of the fantastic detail and much-loved characters 'Harry Potter' fans have loved for over twenty-five years.

"Each season will bring 'Harry Potter' and these incredible adventures to new audiences around the world, while the original, classic and cherished films will remain at the core of the franchise and available to watch globally."
