Everything we know so far about the new Harry Potter remake series on HBO

Magic is returning to the screen: HBO is preparing a series that will expand the Harry Potter universe with new perspectives and details.

Thirteen years after the release of Harry Potter and the Deathly Hallows: Part 2 in cinemas, which marked the end of Harry’s journey on the big screen, the magical universe is set to return in episodic television format.

Under the direction of Francesca Gardiner and Mark Mylod, both known for their work on Succession, HBO’s adaptation of the beloved saga promises to revive the magical world as Harry Potter discovers he is a wizard and leaves his Muggle family to attend Hogwarts School of Witchcraft and Wizardry. Along the way, he befriends Ron and Hermione, and becomes a key figure in the fight against Lord Voldemort, also known as “He-Who-Must-Not-Be-Named.”

This series announcement comes nearly 30 years after J.K. Rowling published Harry Potter and the Philosopher’s Stone, a book that was adapted into a film by Chris Columbus in 2001. In total, the original film saga grossed $7.7 billion worldwide.

Here’s everything we know so far about the HBO Harry Potter series.

How will the series differ from the films?

Each of the seven books will be adapted into a full season. Gardiner and Mylod have explained that they see this series as an opportunity to expand the stories from the books and films without altering their legacy. For example, they have mentioned their intention not to “alter” the look of the Great Hall.

The series aims to delve deeper into the characters’ arcs and explore Hogwarts figures who didn’t have much screen time, including professors and staff at the castle.

Will J.K. Rowling be involved in the series?

One of the most controversial aspects of the Harry Potter universe in recent years has been J.K. Rowling’s comments about trans and non-binary people. Despite this, Rowling will participate as an executive producer of the series.

At a press conference on November 12, HBO chief Casey Bloys mentioned that Rowling is “very, very involved in the process of selecting the writer and the director,” and that her comments did not influence the decision to work with her.

Is the cast known?

Not yet! It has been reported that around 32,000 children have auditioned in Ireland and the UK for the lead roles of Harry, Ron, and Hermione. Since December 5, Gardiner and Mylod have been reviewing auditions and plan to meet with the finalists in January.

As for other key roles, rumours suggest that Mark Rylance (Bridge of Spies) could play Dumbledore, while Paapa Essiedu (I May Destroy You) is a potential candidate for the role of Professor Snape. No deals have been confirmed yet, as the casting process is still in its early stages.

When will filming take place and when will the series be released?

Filming will begin in the summer of 2025 at Leavesden, the same location where the original films were shot. The HBO Harry Potter series is set to premiere on Max in 2026.
