Other mistake: In the opening scene is a paragraph describing why the Top Gun school was started. The word "insure" is used when the word should have been "ensure". They wanted to guarantee the U.S. had superior pilots, not take out an insurance policy.
Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Other mistake: In the final scene of the movie, Megan starts a boat motor and uses the propeller to hit Jason in the face, who has been chained down underwater. But if Jason can only barely reach her foot from underwater, there's no way the boat propeller is underwater far enough to reach his face. (01:17:50)
Suggested correction: The boat was driven a good ways, it's not like they were shallow and then all of a sudden deep. They were deep for a little bit. I mean not so deep like the ocean, but it was a good enough ways for someone to drown. Megan is tall for a girl and Jason is a big guy and the propeller is right at his head/neck.
You are very much mistaken. The boat propeller is too high to reach Jason's face.
Other mistake: When the autoguns fire at the aliens for the second time, there is a flashcut of an alien being blasted apart. Watch closely; it's the same clip of the alien that Vasquez shot and subsequently sprayed Drake with acid. (01:18:00)
Other mistake: After the brief fight between Barnes & Chris, when Barnes has Chris pinned, he cuts him below the left eye with a knife. It is a quick cut with a sharp knife, but instead of a thin bright red line we see instantly a blob of dark blood. This is plain sloppy.
Other mistake: In the scene where Stallone is at the shooting range, after he leaves the morgue, when he pulls out his gun, you can see a target's reflection in a glass pane in front of Stallone. He points the gun at the target and shoots, but the glass is in the way.
Suggested correction: There's no glass in front of him. The glass you're referring to is part of the partitions on the sides. You can see the first one when he and Gonzales walk in and Gonzales is asking what they can do. The reflection is in the 2nd partition that is to Cobra's left. The camera angle just makes it look like it could be in front of him.
Other mistake: The Hitcher reverses his pick-up truck out of the gas station after he drops the lighted match. His wheels, wheel arches and perhaps the underside of the truck would have been soaked in petrol as he drove over the gushing pumps. So as he was burning rubber during this manoeuvre - this would have ignited the petrol on his truck.
Other mistake: The credits for the movie say that they are in alphabetical order, but Peter Cullen is listed before Scatman Crothers.
Other mistake: After finding that he has run over a dummy and not a live person, the officer doesn't resume the car chase even though Roland's panel truck is shown driving only about one block ahead of him with no traffic in between. For those of you who don't know, panel trucks have the get-up-and-go of an arthritic turtle. (01:21:00)
Other mistake: In the scene where Terry is at the computer, and Jim Belushi's character surprises her while pretending to be a Sperry repairman, they keep turning the monitor on and off. But the last time you hear a beep, which is supposed to be Terry turning off the monitor, her hand is nowhere near where the button would be. They obviously added the sound effect later.
Other mistake: In the scene when the Kurgan breaks into the tower house looking for Connor, he breaks down the front door. As the door fragments, we can see it is not made of wood but polystyrene.
Other mistake: In the scene where Howard falls asleep in Beverly's apartment window and his wallet falls out, she takes out the money. The city on the bill says Washington DC instead of Marshington DC. (00:19:00)
Other mistake: Hendershott fires the L.A.W., then gets killed. Nobody reloads it, but Wanda fires it at the beer truck as she dies.
Other mistake: When the family is leaving and the door is shut you see the floor lock (common in older homes) on the door engage. When Brad goes back in through the window you see him run down the stairs. He gets to the door and unlocks 2 locks on the upper part of the door but not the floor lock.
Other mistake: As Packard backs out of the cemetery there's no damage to his car, despite crashing through an iron fence and headstones.
Other mistake: After Jack climbs up the ladder and through the floor he then runs right to the locked door, all this takes about ten seconds. Somehow in those few seconds Wang, Gracie, and the rest of the girls have all made it up the same ladder and coming around the corner when he gives him the signal to come to the door when there's no way they couldn't have all done it that quickly.
Other mistake: The spot light from the school building spotted the scuba divers with yellow oxygen packs, but the guerrillas did not respond.
Other mistake: During the fight on the dam between von Ragnar and Lance, the protective cover of von Ragnar's deadly middle finger nail is never seen until the closeup shot of von Ragnar removing it.
Other mistake: Lakella seems to disappear from the movie after the battle.
Other mistake: The end credits are plagued by the biggest compilation of spelling mistakes you'll ever see. The French cast in particular has 2 out of 2 actors with their names wrong (PallarOy instead of PallarDy, a female, Danièle, turned into a male Daniel) and so many errors in the technical cast to make some of them impossible to identify.
