Author J.K. Rowling made her first visit to the set of HBO's upcoming Harry Potter TV series amid ongoing production. The series, based on her books, began filming in July at Warner Bros. Studios Leavesden and other UK locations, with a planned release in 2027 on HBO and Max. The visit comes against the backdrop of Rowling's ongoing controversies over her views on trans issues.
Visit Details
J.K. Rowling, the creator of the Harry Potter franchise, visited the production set of the new HBO TV series adaptation for the first time. Filming for the series started in July 2025, taking place primarily at Warner Bros. Studios Leavesden in the UK, along with additional locations across the country. The project is expected to premiere on HBO and HBO Max sometime in 2027.
Production and Involvement
HBO has maintained close collaboration with Rowling throughout the development process. A network spokesperson stated last year, “J.K. Rowling has a right to express her personal views. We will remain focused on the development of the new series, which will only benefit from her involvement.” HBO chief Casey Bloys added at a press event that Rowling was “very, very involved in the process selecting the writer and the director,” and noted that her statements have not impacted casting, hiring of writers, or production staff.
Background Context
Rowling has faced significant controversy since 2020 due to her public expressions of anti-trans views, which she has reiterated frequently. Variety reported in 2024 that she posted or reposted over 200 times on trans-related issues in a two-month period. In response, several Harry Potter and Fantastic Beasts actors, including Daniel Radcliffe, Rupert Grint, and Eddie Redmayne, have voiced support for trans and non-binary individuals. A notable public rift occurred with Emma Watson, whom Rowling criticized online after Watson expressed sympathy for those facing hate. Watson later shared she was “most upset” that “a conversation was never made possible” but remained open to dialogue. Warner Bros. issued a 2020 statement emphasizing the importance of a diverse and inclusive culture without directly addressing Rowling's comments.
Deadline was the first to report on Rowling's set visit.
