Corrected entry: The Ghostbusters cross their proton pack streams which results in a tremendous explosion. The next scene shows the blast pushing Mr. Sta-Puft away from the building. A second later another scene shows the explosion radiating outward from the roof. The only part of him shown over the edge of the building is his head and his right hand. To get all over the Ghostbusters, marshmallow would have to be blown in the opposite direction against the force of the blast. It makes sense that there was marshmallow all over the street, but how did it land on the Ghostbusters?
Corrected entry: At the end when they cross the streams, Stay Puft is looking at them at their level. He was nowhere near that tall.
Corrected entry: When Gozar, or the voice of that lady character is telling the Ghostbusters to "choose" the form of their destructor, Peter tells them the example about J. Edgar Hoover and that they need to clear their minds. Well if he was thinking of J. Edgar Hoover at the time, shouldn't he have came out instead? (01:29:41)
Corrected entry: Why did the Gatekeeper and Keymaster (the dogs) have to possess Dana and Louis? From everything we see, the dog statues are at the top of the building, and the demon dogs break through. Then they go and destroy half the building to find people to possess. They wait a while, Louis gets taken to the Ghostbusters, and Dana stays in her apartment. Then even later they go back to the top of the building, and stand exactly where they were standing after changing from the statues where the lightning changes them back into the demon dogs. What was the point of them leaving, possessing people, then coming back?
Corrected entry: In the sequence where the ghosts go berserk in New York, one ghost shoots itself into a taxi cab through the muffler. Right after that a man goes into the taxi, and we see the ghost at the wheel, in the form of a live corpse. The taxi then proceeds to drive off. However, it is now being driven by a regular guy, easily visible in the shot for a second or two.
Corrected entry: Scene where Venkman gives Egon the candy bar and says, "You've earned it": in the original film version, Venkman gives Egon a Nestlé Crunch bar; in the VHS/DVD versions, the candy bar is a Payday. I'm guessing there was a contract dispute with Nestlé sometime between the film release and the video release of the movie
Corrected entry: In the ballroom scene, when Egon shoots the cake, it explodes seconds before the proton beam touches it. (00:36:10)
Corrected entry: In the scene in the hallway at the hotel with the green ghost, the ghost goes through a wall right above a vase of ferns, and about a second later, a cart crashes into the table with the ferns on it. The ferns go up into the air and out of the shot, but they never come back down. (00:33:14)
Corrected entry: When Ray and Winston were driving across the Brooklyn Bridge around midnight in the Ectomobile, Ray quoted a verse of Scripture claiming to be "Revelation 7:12". Although in actuality the verse that contains "...opened the sixth seal...and the sun became as black as sackcloth, and the moon became as blood..." Actually was Revelation 6:12. The writers were one chapter off. (01:03:38)
