You could probably make a list of Ghostbusters trivia and Easter eggs purely based around Gozer. For example, did you know that Paul Reubens as in Pee-Wee Herman was originally in line to play the film's supernatural antagonist, because the character was originally meant to look like a mild-mannered, regular guy? That's probably because that's closer to Gozer's probable namesake, with the title taken from a Gozer Chevrolet dealership in upstate New York. Oh and there's a documented haunting in England where the name appeared mysteriously throughout the house, which is less fun.
