Corrected entry: If the Rex can only see things that move, how did she find the goat?
Corrected entry: When the insurance man runs into the bathroom, and is eaten by the T-Rex, why would they have bathrooms on an automated car tour where you're not supposed to open the doors anyway? Even if it were an emergency staff bathroom, it probably wouldn't have multiple stalls.
Corrected entry: A live bull is lowered in a sling to feed the raptors in the pen, but when the shredded sling is brought back up, there's no blood on it. How could they have shredded the sling without drawing blood on the bull? (00:32:40)
Corrected entry: The dilophosaurus is far too small; in reality they stood at about two metres tall.
Corrected entry: Early in the movie, in the scene where the goat is presented to try and attract the T-Rex, Lex claims to be a vegetarian. Yet later in the movie, Lex is eating jelly, which contains gelatin, an animal derived product, which is unsuitable for vegetarians and vegans.
Corrected entry: They are somewhat undergunned with 12 gauge for deadly, strong and fast animals like T Rex and Raptors. Express rifles in African calibre would work better, or even the mighty powerful .460 Weatherby magnum. (01:32:40)
Corrected entry: When the velociraptor entering the park attacks the "gatekeeper," the staff use tasers to get it to stop. These tasers probably operate at a high voltage and possibly more amps. In reality, the gatekeeper and Robert Muldoon would be dead since they would've received the same shock or lower. Humans can die at 200 milliamperes (0.2 amps), which is probably what would've happened to Robert and the worker, if the velociraptor didn't kill him.
Corrected entry: When they first arrive at the park, they see a brachiosaur feeding on the leaves of a tree. When the dino gets on its hind legs to get a hold of the top branch, it could've easily reached the top branch without taking the extreme energy to lift itself. This counteracts anything that would naturally happen but is used to make the impressive landing that it makes coming down.
Corrected entry: When meeting Muldoon, Dr. Grant calls Muldoon "Greg" instead of using the character's first name, which is Robert.
Corrected entry: In the initial scene where Ellie rushes from the emergency bunker to the underground power station, she must first open the door before slamming it closed behind her. Shortly thereafter (immediately after throwing the breakers and restoring power to the park) a velociraptor attacks her and she must flee to escape the bunker. If a raptor had pursued Sam Jackson into the same underground bunker, then why was the initial door that Ellie had to enter closed? Are we to believe that the raptor politely closed the door behind it before continuing its pursuit of Sam Jackson?
Corrected entry: At the beginning when the insurance man says "I represent the investors, if they aren't satisfied, I'm not satisfied." He meant to say "I represent the investors, if I'm not satisfied, they aren't satisfied." He is the eyes and ears representing the investors, he has to be the one satisfied that their money is not being wasted.
Corrected entry: In the scene when the characters are having dinner, just after the first waiter delivers the food to the table, you can see the second waiter in the top left corner waiting for his cue to deliver the food to the table. You see him waiting a few seconds for the other waiter to return and then he comes into shot completely, with the plate. (00:33:00)
Corrected entry: The brachiosaurus is shown to be chewing, but they didn't chew, they swallowed food whole. Also when Dr. Grant and the kids are in the tree, the brachiosaur's head is larger than it should be.
Corrected entry: If you listen carefully, you can hear some common Costa Rican birds, including a keel-billed toucan and a three-wattled bellbird. Since it was filmed in Hawaii, they must have taken the time to add a soundtrack of Costa Rican birds. Unfortunately, these birds would not likely be found on an island that far off the coast. The bellbird in particular occurs only at mid-elevations in the Costa Rican mountains. These birds are not on Cocos Island, 340 miles off the Pacific Coast of Costa Rica. Cocos is considered the inspiration for the fictitious island in the movie. Since Cocos is uninhabited, and visits are strictly restricted, a soundtrack from there would have been extremely difficult to get. The fact that they went so far as to add a Costa Rican soundtrack is pretty impressive.
Corrected entry: In the end scene where they are loading Ian onto the chopper, he is bleeding and his pant leg is cut. But when they show him again, the bleeding has stopped in a matter of minutes, and his pants have magically grown a new leg. (01:53:30)
Corrected entry: Dr Sattler is hardly out of breath after she is told to run towards the shed by the game warden. (01:34:55 - 01:35:25)
Corrected entry: At the end the T-Rex comes in and saves the day by killing the raptors. Where did he come from? He's huge and no way he could have fit through any of the doors. Second, how come nobody heard him coming? He can be heard many other times during the movie before he shows up. Finally, how come nobody saw him? He's huge and can be seen from a distance.
