The team who you’re gonna call is not QUITE back in the first trailer for Ghostbusters: Afterlife, but there are plenty of clues that point towards the return of an old friend.
First up we get this symmetrical book stacking just like the Philadelphia mass turbulence of 1947 AND the New York Public Library in the original Ghostbusters film. While this isn’t a trademark of Gozer, it did mark the beginning of a very busy time for ghosts in 1984 that culminated in the return of the Gozerian.
Of course, the most telling clue is the Shandor Mining Company. Ivo Shandor was the architect and Gozer worshipper who designed Dana Barrett’s apartment complex on central park west. That building was an antenna of sorts, a gateway to bring Gozer into our world. It would seem that Ivo Shandor had another location that served a similar purpose as the one in Manhattan.
