Warner Bros. Discovery is developing a new Harry Potter television series for its Max streaming service. The series will be a faithful adaptation of J.K. Rowling's seven books, with each season focusing on one book. Rowling is involved in the project as an executive producer and will have creative control over the series. The series will feature an entirely new cast and is expected to debut in 2026. Warner Bros. Discovery is hoping the series will be a major hit and help to revitalize the Harry Potter franchise.
