Corrected entry: During the scene when Laura Dern is running away from the Velociraptors towards the main door, you can see that she's dragging along a torch attached to her waist. In the next shot, the torch has gone missing because it caught on the door, but her pink shirt has disappeared completely with no good reason.
Corrected entry: When Nedry slips and falls on the small waterfall, you can see the area in which he slid down is smooth, but in the next view of the waterfall, the smooth slide is gone.
Corrected entry: During the scene in which the T-rex first breaks out of its paddock and terrorizes everybody, it pushes the Jeep containing Timmy over the edge of the cement cliff, narrowly missing Dr. Grant and Lex. The following shot shows the Jeep landing, overturned, amidst the branches of a large tree. However, when Dr. Grant scales the tree to rescue the trapped Timmy, the Jeep is completely righted.
Corrected entry: Just before the T-Rex attacks the Explorers, there is a shot of Malcom and Grant talking with the headlights from the other S.U.V. shining into the rear window. How is this possible if they are in the second vehicle?
Corrected entry: When the group is watching the 'Mr. DNA' film, when the camera cuts back to a wide shot of the whole "clean-room", if you look near the back of the room on the left side, there are two vending machines full of goodies. Vending machines in a clean room? Please.
Corrected entry: Why aren't there subwayesque service tunnels all round the island to permit the staff to travel hidden from the dinosaurs/sundry other emergencies/all the other incidental occurrences that make every other undertaking on our planet use similar tunnels? Expensive and laborious, but if you have the resources to make dinosaurs, everything else is a breeze.
Corrected entry: When the visitors are watching the baby dinosaur breaking out of the egg, Dr Malcolm discusses the possibility of the dinosaurs breeding. He is told by an engineer that this would be impossible as the genetic engineering has created only female dinosaurs. Later, when Dr Sattler examines the sick Triceratops, she asks the park vet what 'his' symptoms were. Although this was probably just a slip of the tongue, it's still worth noting.
Corrected entry: When we first met Nedry in San Jose Dodgson informs Nedry that he will receive a total of "One-point-five million dollars if he gets all 15 species off the island." Take a closer look at that test tube receptacle. If you look when he is closing the test tube receptacle after he steals the the DNA you can see that there is only enough room for ten species.
Corrected entry: When the T-Rex moves to Dr. Grant and the boy they hold still because it can't see things that don't move. Unfortunately though, T-Rex's have a highly developed sense of smell and would certainly have known they were there.
Corrected entry: At the badlands when Alan touches the monitor and it messes up and the kid speaks up. How could the kid see the screen? Even we can barely see it. The crowd moves to reveal the kid way in the back of them and short as they are tall. He couldn't see the screen from there.
Corrected entry: When the Raptor is chasing Grant, Ellie, Tim and Lex through the computer lab, and they get into the ceiling, the Raptor jumps up on a table ad pokes his head through the ceiling. When Grant kicks it in the eye, and it falls, the table is gone. (01:50:40)
Corrected entry: When the doctor is showing off the piece of amber that they have gotten the DNA from, there is a problem. The mosquito in the amber is a male, as one can tell by the antennae. Because it is only the female mosquito that feeds on blood, the male should only have nectar in its stomach. To make it worse, in that species of mosquito, Toxirhynchites, both the males AND females are flower feeders, and would therefore have no blood, or dinosaur DNA in their stomachs. (00:25:00)
