Harry Potter (Season 2)

Harry Potter is heading back into production for its second season at HBO, adapting the second book in J. K. Rowling's series, Harry Potter and the Chamber of Secrets. The greenlight comes as Season 1 wraps production ahead of its Christmas 2026 premiere. Jon Brown, a writer on the first season, has been elevated to co-showrunner alongside Francesca Gardiner to manage the overlapping production schedules. The series is produced by HBO, Warner Bros. Television, Brontë Film and TV, and Heyday Films, with Mark Mylod directing multiple episodes. Production is scheduled to begin this fall at Warner Bros. Studios Leavesden in the UK, maintaining the accelerated timeline designed to keep the young cast aligned with their characters' ages across the planned decade-long, seven-season adaptation.
