Corrected entry: After Timmy has been electrocuted and is back safely you see his hair all sticking up. Same when he and his sister are eating. Upon noticing the Raptor they run to the kitchen, Timmy's hair is nice and neat.
Corrected entry: In order to open a park like that to the public (and obviously it's close to the opening date) Hammond would have to convince more people than just his investors. In reality, the park would have to pass a security review, and those auditors would definitely ask questions like "What happens in case of a catastrophic computer failure?" Something tells me the answer "All the fences turn off and you have to run across the compound to turn them back on manually" wouldn't sit too well with them.
Corrected entry: All of the strands of the high voltage electric fence Tim was hanging on were tied together. This means that all of the wires and Tim were at the same electrical potential. Tim wouldn't have gotten shocked. This phenomenon is referred to as "bird on the wire." Birds sit on live electrical wires all the time and do not get shocked because they are not touching the ground and therefore the electricity has no where to go. The only way for Tim to be shocked would be for him to be touching the fence and the ground simultaneously.
Corrected entry: When Muldoon prepares to shoot the raptor he unfolds his rifle butt. However the rifle is already unfolded when he and Ellie are passing the raptor pen.
Corrected entry: Right towards the end of the film just after Lex manages to reboot the security system the raptor breaks through the glass into the control room. Dr Grant shoots three times whilst he's on the phone to Hammond. There are threes holes in the glass but the subsequent shot of the gun shows it is a shot gun, not a rifle (the red shotgun cartridges can be seen) which would make many holes, not one for each shot. Even using the choke on the end of the barrel there would still be many holes and a single bore shotgun is basically a musket so there would have to be more than one hole for each shot of the gun.
Corrected entry: When Alan becomes overwhelmed after seeing the movie's first dinosaur, he staggers and sits down on the ground... But as he is bending over before sitting, there are already grass stains and/or wet spots on the seat of his pants.
Corrected entry: When Dennis gets back in the car after the dilophosaurus spits at him, he turns to see the dinosaur in the car with him. But how did it get in? The door was closed.
Corrected entry: At the end of the film, they are in the helicopter and in the air, you see a shot of inside the helicopter. Outside the opposite window is land, then when the shot changes to view the large birds, they are flying above water. Inside is always land, outside is always water. Then when the camera pans out to view the helicopter fly away, it is above the ocean with no land in sight.
Corrected entry: During the external shot of Nedry getting attacked by the dilophosaurus, there is a clear reflection of stage lights near the jeep's front left wheel. (01:11:15)
Corrected entry: Dr. Grant holds his canteen out the window in order to get water to drink. But there is no funnel on it. It would take a very, very long time for rain to drop through that small hole to fill the bottle with any drinkable quantity of water, even in the heaviest of rains.
Corrected entry: Before the T-Rex chases Ellie, Robert and Malcolm in the jeep, we see Ellie get in the passenger side of the jeep, and Robert get in the driver's side. Over the course of the chase scene, Robert and Ellie switch seats.
Corrected entry: In the scene where Gennaro is about to be eaten, when the T.Rex knocks over the bathroom walls, you can see that the bathroom tissue dispensers on the wall behind Gennaro are painted images on the wall and not actual dispensers. It is clear once the wall has fallen that the dispensers have no depth and are two dimensional images. (01:02:00 - 01:03:00)
Corrected entry: In the scene where Hammond is sitting at the long table and eating ice cream, Ellie comes in and sits at the opposite end. All of the ice cream barrels are near him. When a scene cuts to Ellie, there is an ice cream container near her and towards the end of the scene she gets some ice cream. At the end of the scene, the shot shows both of them and the table and there is no ice cream within Ellie's reach. (01:21:50 - 01:24:55)
Corrected entry: When the tour trucks enter the T-Rex paddock, the electrified fence is missing an entire section, from the tunnel they exit to the first section of fence.
Corrected entry: Ellie finds the upturned car that Timmy had been stuck in, but how did she get down there? It's down an almost vertical ledge. Not only that but she got from the bottom to the top incredibly quickly.
Corrected entry: During the T-rex attack scene, it comes through the now non-electrified fence to get to the Ford Explorers. However when the T-Rex is pushing the Explorer over the wall, there is now a 50+ foot dropoff it would have had to climb.
Corrected entry: In the scene at the badlands, when Hammond's chopper has landed and Grant goes to the trailer and opens the door, the trailer looks to be around 8 feet (three meters) wide. But switch to an interior shot and it is suddenly more like 30 feet (ten meters) wide.
