Potterheads, unite!

After hearing of the *extremely* exciting news that a new addition to the Harry Potter universe would be coming in the form of a TV series, we have just been given another pretty major development… cue the cast list!

Now, we’re well aware that fans have countless questions that NEED answering before we officially head back to Hogwarts. When will the episodes come out? And what will it be about? Whether you’re a fully-fledged fan or just a curious muggle, we’re breaking down everything we know thus far about the new Harry Potter TV series. 

Will There Be A New Harry Potter TV Series?

After announcing the series in April 2023, Warner Bros. Discovery has officially commenced pre-production on the Harry Potter continuation.  Along with this news, they have also announced an open casting call for the Harry, Hermoine, and Ron 2.0!

Concerning the show’s creative team, it was confirmed by HBO chief Casey Bloys in a press conference on November 12, 2024, that J.K. Rowling was “very, very involved in the process of selecting the writer and the director,” of the new series, despite her controversial comments online against transgender and non-binary individuals.

What Will The Harry Potter TV Series Be About?

Well, without being about to go into much detail, we can tell you that the new Harry Potter TV series will be a reimagining of the entire Harry Potter story as we know it!  Whilst some fans think this means that the series will adapt each OG book into a new TV season, nothing is set in stone.

HBO CEO and Chairman Casey Bloys has revealed to Deadline that the project would be on-air for “10 consecutive years.”

“This new Max Original series will dive deep into each of the iconic books that fans have continued to enjoy for all of these years,” she said, confirming that the revamped show will be “a faithful adaptation.”

Who Is Cast In The TV Series?

Drumroll please… we can confirm that the beloved role of Albus Dumbledore will be played by John Lithgow!

As for the rest? 

  • Minerva McGonogall will be portrayed by Janet McTeer. 
  • Severus Snape will be played by Paapa Esseudu. 
  • Groundskeeper Rubeus Hagrid will be played by Nick Frost.
  • Quirinus Quirrell, will be played by Luke Thallon.
  • Argus Filch, will be portrayed by Paul Whitehouse.

The big three (Harry, Ron and Hermione) are still being decided upon, and according to Variety, after a large casting call was thrown out, more than 30,000 actors submitted their details to audition for the iconic characters!

When Will The Harry Potter TV Series Premiere?

Unfortunately, we don’t have a release date for the upcoming Harry Potter series yet. However, having been confirmed to begin filming in mid-2025 in Leavesden, England — the same location as the films — the series should be hitting streaming services in 2026!
