All About HBO's Harry Potter TV Series, from the Writer to the Director

Get ready to return to the Wizarding World of Harry Potter.

Following reports in early April 2023, Warner Bros. Discovery confirmed their plans for a brand-new Harry Potter series based on the best-selling novels of the same name during a presentation to press and investors on April 12, 2023.

"We are delighted to give audiences the opportunity to discover Hogwarts in a whole new way," said Casey Bloys, Chairman and CEO, HBO & Max Content in a press release.

The series marks the latest onscreen adaptation of Harry Potter, which was first released in 1997 with the book, Harry Potter and the Sorcerer's Stone. In addition to the popular eight-movie franchise starring Daniel Radcliffe, Rupert Grint, and Emma Watson, a spinoff prequel titled Fantastic Beasts and Where to Find Them starring Eddie Redmayne was released in 2016, followed by two sequels, Fantastic Beasts: The Crimes of Grindelwald (2018) and Fantastic Beasts: The Secrets of Dumbledore (2022).

An original play titled Harry Potter and the Cursed Child, which premiered on the West End in London and later hit Broadway in New York City, also followed a grownup Harry, Ron and Hermione as their children attended Hogwarts.

While the Harry Potter films were a worldwide phenomenon during their initial release, the franchise has become embroiled in controversy in recent years. Author J.K. Rowling has come under fire after making comments widely condemned as anti-transgender in 2020, while the Fantastic Beasts franchise has been plagued by a series of controversies surrounding its key players, including Ezra Miller and Johnny Depp, the latter of which resigned from his role as villain Gellert Grindelwald after losing his libel case in the U.K. in 2020.

What will the Harry Potter series be about?

Unlike other book-to-film adaptations such as The Hunger Games taking the prequel route with new releases, the upcoming series "will be a faithful adaptation of the beloved Harry Potter book series," per an official press release from Warner Bros. Discovery.

The release adds that "each season will be authentic to the original books and bring Harry Potter and these incredible adventures to new audiences around the world, while the original, classic and beloved films will remain at the core of the franchise and available to watch globally."

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

In their official press release, Warner Bros. Discovery confirmed that Rowling will serve as an executive producer along with Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV and David Heyman of Heyday Films.

Who is writing and directing the Harry Potter series?

In June 2024, HBO announced that the new series will be written and executive produced by Francesca Gardiner, whose past credits include Succession, Killing Eve and His Dark Materials.

Meanwhile, Mark Mylod will executive produce and direct multiple episodes of the series in association with Brontë Film and TV and Warner Bros. Television. Mylod is best known for directing numerous episodes of Succession, which earned him two Primetime Emmy Awards, in addition to helming 2022's The Menu.

Will the original Harry Potter cast members appear on the series?

Where can you watch the Harry Potter series?

Despite earlier announcements that the show would be a Max original, it was reported in June 2024 that the series will now air on HBO. Though Deadline reports that like all HBO originals, the series will likely be available to stream on Max.

How many seasons will the Harry Potter series include?

The official press release from Warner Bros. Discovery confirms that the new show would be "a decade-long series," however, it's unclear just how many seasons that will entail.

Bloys noted that it would be up to the showrunner how to split up the seven books, but the first season would mostly revolve around Harry Potter and the Sorcerer's Stone, while potentially including bits from other books.

When will the Harry Potter series be released?

Though Warner Bros. Discovery didn't confirm a release date in their press release, Deadline reported that it could be aiming for a 2025/2026 premiere.
