Warner Bros. Discovery announces a 2026 “Back to Hogwarts” programme for Harry Potter fans worldwide, built around the 25th anniversary of the film “Harry Potter and the Sorcerer’s Stone” (the U.S. title for “Harry Potter and the Philosopher’s Stone”). The initiative combines anniversary programming with new marketing material for the upcoming HBO Original series.

According to the outlets, the celebrations center on Sept. 1 and include a weeklong theatrical re-release of the 25th anniversary film. In addition, the company plans live fan events held across four global regions, described as part of a larger set of on-the-ground and community activities. The programme also features exclusive content tied to the franchise and provides fresh glimpses of the HBO Original series, which is expected to expand the franchise in a television format.

The announcement is presented as an extended global fan celebration that blends reissued theatrical content, live events, and promotional previews, with the HBO series preview component positioned as part of the broader build-up toward the next chapter of the franchise.
