Corrected entry: In the bone organ scene, before playing the last note, Andy says that she doesn't know if it's an A sharp or a B flat. On a piano or organ with the standard keyboard (and there is no reason to think that this organ uses anything else) these notes are the same and played with the same key.
Corrected entry: The scene with the octopus wasn't originally a deleted scene because I remember as a kid watching this movie, they put a tape player inside of the octopus mouth and it starts dancing to it, so the Goonies get away. I have never seen the movie on VHS or DVD so I shouldn't know this.
Corrected entry: When Mikey holds the doubloon up from a distance, the two rocks and the lighthouse are a perfect match for the three holes in the coin. If the coin was really from 1632, how could the lighthouse even be in it? Lighthouses weren't made until a LONG time later in the 1800's or so.MasterChief3624
Corrected entry: In the scene where the kids are entering the hole in the basement of the lighthouse (i.e. the start of the tunnel), Data is seen wearing a pair of white Nike shoes. In the next shot, where his feet are coming down the tunnel, his shoes have changed to a pair of grey/black Nikes.
Corrected entry: When all the kids are in the well and they're all shouting at Troy at the same time, the name "Troy" is shouted twice by one of the characters and the second "Troy" overlapped the first one.
Corrected entry: At the end of the movie when they are all looking at the ship sail off into the sunset, there is one problem: this took place in Oregon and the sun sets over the ocean in the west, which is correct. But the kids coming out the cave takes place in the morning, so the sun would not have been there, as it comes up in the east.
Corrected entry: The Goonies discover a bunch of candles in Chester Copperpot's backpack and take them; among them is a stick of dynamite. Dynamite essentially consists of nitroglycerin soaked in sawdust or diatomaceous earth; old dynamite tends to 'sweat' the nitroglycerine, which makes handling the stuff very dangerous. Since the stick has been lying there for about 50 years, and with all the jostling the Goonies go through from that point, it should have gone off.
Corrected entry: The movie says that the Goonies' house is in danger because it's wanted for a golf course. But they live on a very steep and hilly street - exactly the opposite of the open, flat (if with low hills) kind of land needed for a golf course.
Corrected entry: In the end, Rosalita is the one who saves them all by running over and shouting (in Spanish, which Mouth translates) for them not to sign the contract, since they have the jewels they can use to get the money they need. But since it's already been established that she doesn't understand English, how would she know that they needed money? How would she know that they're signing something precisely because they didn't have it? Mouth never told her, and nobody else speaks any Spanish to have told her.
Corrected entry: At the end, it is Rosalita who saves the Goonies' homes from being sold, because she opens the marble bag to find all the precious jewels and runs over to everyone shouting "Don't sign." There's a huge problem with this though: it's already been established that Rosalita doesn't speak English.
