Corrected entry: The sweat on Muldoon's forehead changes in the scene where he tries to shoot one of the raptors.
Corrected entry: At the very end, the T-Rex barges into the Visitors Center and saves everyone from almost certain peril. Only problem is that we didn't hear the Rex walk up to the center like we did everywhere else. (01:52:20)
Corrected entry: At the beginning, we can assume that there are at least three raptors inside the container. But when the raptors push the container forward and drop the gatekeeper down, we can see some workers went inside the container or, at least, in front of it. If so, why didn't they stun the raptor that is holding the gatekeeper? Furthermore, they didn't get killed by the other raptors.
Corrected entry: When the kids are eating in the hall, I keep wondering about Tim. If he'd just received a serious electric shock, would he even be able to eat? Most people that get even a minor shock can't eat for a couple of days. (01:43:05)
Corrected entry: At the end after the raptors have chased the group into the main lobby, the hanging skeletons overhead start falling on the people. Watch as a huge bone falls practically on top of Tim. This is obviously a very staged shot, because his hands are not covering the back of his head, which is a natural, protective human instinct. His hands are just on the sides of his head. For a real reaction, notice Ellie's, which is (I think) right beforehand - she curls into a ball, and covers the back of her head.
Corrected entry: In the kitchen confrontation, the two little children are strong enough to successfully force the freezer door shut on a charging Velociraptor. Twenty seconds later, in the control room, the two adults are only barely able to hold a door shut against a charging Velociraptor.
Corrected entry: Even though the film is titled "Jurassic Park", the only dinosaur depicted from the "Jurassic" period was the Brachiosaurus. The T-Rex, Triceratops, Velociraptor, ect were all actually from the "Cretaceous" period which was later. This occurred throughout the whole trilogy.
Corrected entry: In the scene where they are "rebooting" the computer system, Lex states "I know this, it's a UNIX system." The scene then cuts to a shot of the interface which is a 3D "flyover" interface. There are, at this time, no commercial UNIX systems that employ such an interface, so there was nothing on the screen to let her know what operating system that goofy interface (probably written by Nedry) was attached to.
Corrected entry: After Ian Malcolm is attacked by the T-Rex and thrown into the debris of the destroyed bathroom, he has blood on his face. When Sattler and Muldoon find him, the blood is gone, not a trace left! And it had stopped raining at this point, note Malcolm's dry clothes and the blood still on his leg, there's no way it could've been rinsed away.
Corrected entry: When on the tour, the two cars pass by the T-rex enclosure where they see a goat raised into it from below. Then, they pass by without seeing the dino. Later in the movie they pass by the same enclosure going the opposite way. The cars would continue on their journey and not backtrack. If they did go backwards on the path to get back to the visitor's center, the cars would be facing the other way.
Corrected entry: In the helicopter scene at the beginning of the movie, Malcolm is talking to Dr. Grant and Dr. Sattler and he is deliberately chewing gum as he talks. In the next shot, Malcolm suddenly isn't chewing gum. He then unwraps a piece of gum and places it into his mouth.
Corrected entry: When the crew is preparing to enter the tour trucks, John points out the trucks are powered by the track running below it. When he directs Dr. Sattler and Dr. Grant to enter the vehicle, the entire bottom of the rear truck is visible and no connection to the track is present.
Corrected entry: In the scene with the raptor in the kitchen, the raptor breathes on the window and fogs it. But reptiles are cold-blooded, which means their insides, and consequently their breath is the same as the ambient temperature. The glass would not fog.
Corrected entry: In the scene where Dr. Grant and the two kids climb the electrified perimeter fence, just before Dr. Sattler reactivates the power, Dr. Grant can be seen from underneath while climbing. After walking for two days in lots of mud and rain, his shoes are still pretty clean.
Corrected entry: In one of the laboratory scenes there is a Zeiss compound microscope sitting on the work bench. It has a binocular head on backwards and it can't be used that way. (00:27:00)
Corrected entry: At the end, Hammond pulls up in front of the Visitor Center in a jeep with the injured Ian in the back. Hammond is a feeble old man who walks with a cane - how did he manage to get Ian into the jeep?
Corrected entry: When Hammond's visitors are viewing the 'movie' about how DNA is extracted, a hypodermic syringe is shown taking a DNA sample from an amber source. It's clear that the syringe is one used exclusively for a tuberculosis skin test. It's even labeled as such because you can see the word 'tuberculin' on it.
Corrected entry: When Nedry is seen stealing the embryos from the freezer, in one extreme closeup shot of his hand he isn't seen to be wearing any gloves. This is absurd as some sort of protection is absolutely necessary while holding objects stored at such low temperatures (indeed Crichton puts it at -10 degrees). (00:54:50)
