For the 20th anniversary celebration, Daniel Radcliffe, Emma Watson, and Rupert Grint will unite American film producer Chris Columbus and other cast and crew from all eight Harry Potter films. HBO Max officially unveiled the reunion with a 52-second video that showcased spectacular moments from Harry Potter's adventures, as well as those of his friends and foes, as they confirmed the reunion.
