The original Hogwarts wizarding trio are reuniting to recount their adventures from two decades ago.

Daniel Radcliffe, Rupert Grint and Emma Watson will join filmmaker Chris Columbus and other cast members from all eight “Harry Potter” films for the first time in an HBO Max retrospective special to celebrate the anniversary of the franchise’s first film, “Harry Potter and the Sorcerer’s Stone,” which premiered 20 years ago today.

“Harry Potter 20th Anniversary: Return to Hogwarts” will premiere on HBO Max on New Year’s Day, Jan. 1, 2022. The feature will “tell an enchanting making-of story through all-new, in-depth interviews and cast conversations.”
