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.
Corrected entry: All the scenes in the cave with the pirate ship would surely have been a lot darker, after all they're completely enclosed in a cave with no light source, it would have been pitch black. Instead everything is brilliantly and brightly lit.
Corrected entry: If the secret tunnel system leads through the pipe-filled passage below the country club, then why have the tunnels remained such a secret? Surely when those pipes were built or maintained, the workers would have noticed the tunnels.
Corrected entry: At the beginning of the movie, when the Goonies find the map in Mikey's attic, Mikey says that the Inferno was chased into the cave by the British Armada, who then sealed the entrance of the cave with cannon fire, trapping One-Eyed Willy and his crew inside. Yet near the end of the movie, Mama Fratelli sets off a trap which makes the blocked entrance of the cave crumble, and revealing the mouth. If One-Eyed Willy was able to build a trap that could do this, why didn't he just unblock the entrance and sail away to enjoy his plundered wealth, rather than stay trapped in that cave and die.
Corrected entry: When Data falls into the pit where the spikes are at the bottom, he sets off a device where a set of plastic teeth catch the roof of the pit and save him. Plastic teeth like that would not catch a spike at the top of the pit and still hold Data up.
Corrected entry: If all the kids entered the same water slide, how is it they exit through different holes? There is no shot showing them splitting up. In fact, in one shot, two of the kids are shown almost on top of each other when sliding down the water slide.
