HBO is developing a new series based on the Harry Potter books, aiming to adapt each book into a dedicated season and revive the franchise after the mixed reviews of the Fantastic Beasts films.

The network is committed to a faithful adaptation of J.K. Rowling's original material, striving to remain truer to the source than the previous film franchise.

To support this ambitious project, Warner Bros. is investing over $1 billion to expand its Leavesden studio, which includes building a school for the cast and enhancing infrastructure.

These upgrades are essential as the studio plans to produce multiple long-running series over the next decade.

Key casting announcements have been made, with John Lithgow portraying Albus Dumbledore, Janet McTeer as Minerva McGonagall, and Paapa Essiedu taking on the role of Severus Snape.

However, J.K. Rowling's involvement as an executive producer has reignited debates about her views on gender identity, which could impact the series' public reception.

Essiedu's casting has sparked controversy, leading to discussions online about representation and his Ghanaian heritage.

Executives are optimistic about the series' success, hoping it will last at least ten years, with an expected premiere on HBO and HBO Max in 2026.

Filming has commenced at Warner Bros. studios in Leavesden, where sets are being constructed, including the iconic 4 Privet Drive.

Fans are encouraged by the show's approach, which appears to rely less on green screens and special effects, aiming for a more tangible magical world.

Recent images reveal the construction of 4 Privet Drive, significant to Harry's early life, showcasing Tudor-style houses that differ from the original films' design.

Casting for student characters, including the lead role of Harry Potter, has not yet been confirmed.
