Now, with the Harry Potter TV show's release date nowhere in sight, Heyman provides an update to Total Film (via GamesRadar) regarding the status of the series and what audiences can expect. While it doesn't sound like the show will be coming anytime soon, the producer does tease that this new format will allow for a more faithful adaptation. Check out Heyman's full comment below:
"[On Harry Potter] It’s early days. We haven’t even hired a writer to begin writing. It’s a bit early. But hopefully [it will be] something that’s very special, and gives us an opportunity to see the books, and to enjoy a series which explores the books more deeply."
It is expected that the Harry Potter TV series will premiere on Max (formerly HBO Max) sometime between 2025 to 2026.
The thing is, Philosopher's Stone is short and straightforward enough that the entire book can reasonably be fitted into one movie without leaving out too much details, and every book after that just gets longer and more complicated so the movies have to allocate for time.
A miniseries is probably a good idea just because there's more time to elaborate on things, but I think due to various reasons, Harry Potter just isn't as popular as it was when the movies came out nowadays.
