Corrected entry: During the scene in the subway with the river of slime, as Egon, Ray and Winston are measuring the depth of the river Winston's equipment begins to pull him into the slime. During the struggle to stop this Egon is heard to shout the name Ernie, the actor who plays Winston.
Corrected entry: Why does everyone in the mayor's office and the police think the Ghostbusters are crazy and lock them up? You would think they would believe their story, It couldn't be too outlandish considering a few years before a giant Marshmellow man attacked the city.
Corrected entry: When Ray and Egon are analysing the photos and talking about what sort of take-away to have, Vigo manages to slide the bolt on the door shut. Presumeably this is the only door into the room, so the bolt has to be on one side of the door or the other (being a dark room, it should be on the inside to prevent anyone else coming in). Why didn't they just slide the bolt back? If the bolt was on the other side of the door, then Winston could have slid it back instead of smashing the door open with the fire extinguisher. (00:56:47)
Corrected entry: When Ray is being lowered through the hole in Maine street, he hasn't reached the river of slime yet, but you can see slime dripping from the device he later uses to take a sample.
Corrected entry: When the heroes walk the statue of liberty across New York Harbour, her head etc, are well about the waterline. Yet if you measure the statue herself and find out the depth of the harbour in some places, it would have been impossible for her to take that walk and not "drown". (01:28:23)
Corrected entry: At the end of the movie you see the Statue of Liberty looking down from the rooftop, and then you don't see it the next time we see the rooftop. Then it's on the ground. How can it move without them controlling it?
Corrected entry: The film takes a large liberty when portraying the Titanic. The Titanic we see is complete with a huge hole in one side. The real sinking was nothing like this with small gashes made along the front of the ship, which eventually split in two. There was no large gaping hole like that made when she hit the iceberg. The Titanic was found four years before the film was made, so it was known at that time what condition the Titanic was in. (01:20:35)
Corrected entry: When the Ectomobile, on the way to the birthday party, is driving down the road, you can see that it has the NY plate with the Statue of Liberty on it, which is correct for 1989, but it should have still had the orange plate such would be correct for 1984, when the Cadillac would have been registered.
Corrected entry: During the entire scene where the Statue of Liberty is just outside of the museum, a green screen can be seen in the background anytime there is a closeup of one of the actors in the statue.
Corrected entry: In the scene where Ray and Egon are in the dark room analyzing the photos they took at the museum, watch as they run the one photo through the "spectral analyzer". As they put the photo into the machine on the left side, the photo goes throught the machine at a very slow pace. You can see the photo as they are talking about what food they should get. The photo is about halfway through the machine on the left, when the entire photo magically appears on the right hand side of the machine and is finished being analyzed. When they pull the completed photo out of the right side of the machine, you can see the original photo still being analyzed on the left side. (00:56:26)
Corrected entry: In some shots the slime is red and in other shots it is pink.
Corrected entry: Near the end of the movie, the Ghostbusters are controlling the Statue of Liberty through the streets of New York City. At one point, the statue accidentally steps on a parked police car, smashing it seemingly beyond repair. However, it is fairly easy to notice that the police car is "changed" from a real one to a model - possibly even a Matchbox car - right before the statue's foot comes down on it. Slow motion and/or pausing is NOT needed to see this. It is clear that a (bad) edit was put into place here. The primary tell is that the car's lights go off a split second BEFORE the statue's foot makes contact with it.
