Gary Grooberson (Paul Rudd)
Gary is a science teacher in Summerville who is obsessed with Seismology and the Ghostbusters of the 1980s. It’s Gary who shows Phoebe online clips that feature her grandfather, Egon, and also Gary who lets one of Gozer’s minions out, starting the major conflict of the film.
Gary goes on a date with Callie Spengler and soon finds himself part of Gozer’s plan, though he’s ultimately freed and saved. In the end, we aren’t sure of what his status is but the trailers make it seem as if he and the Spenglers are pretty close.
