Jurassic Park

Corrected entry: Just before Grant and the kids climb the perimeter fence, they hear the T. Rex roaring behind them. How does it then get to the Visitors Centre at the end after the power has been restored to the fence? It hadn't already made a hole in the perimeter fence because after escaping its own pen it spent the night and next morning chasing the jeep and then hunting the Gallimimus.

Correction: Whatever hole it made to get into the pen with the Gallimimus would still be there for him to pass through after the power was back on.

Corrected entry: In the scene when the group look at the sick triceratops, don't you think it's pretty impossible for a dinosaur of that size to do a massive pile of feces that high? That's pretty much its own body weight! (00:50:35)

Correction: OK it's not a particularly scientific explanation, but if they are anything like most animals they go in the same place every time. It could be a cumulative pile from the same or many dinosaurs. Or it could be from a larger Triceratops as the sick one is particularly below average size when compared to many fossil findings.

David Mercier

Corrected entry: Muldoon is supposed to be an expert on velociraptor behavior yet when he is aiming his rifle at a distant raptor he totally forgets their hunting patterns and is surprised when he is attacked from the side. (01:40:50)

Correction: Muldoon has never seen the Raptors hunting prey. The only times he's seen them killing anything is when they are being fed and when the big one ate one of the handlers. As for Dr. Grant's theory of the Raptors hunting, it is just a theory that Muldoon has probably never heard.

Corrected entry: When Ellie returns with Muldoon to find the children, Ellie sees the car that had fallen down into the T-Rex cage. She runs to the site where the Jeep fell. It's a bit strange, because the car fell down several stories into the T-Rex cage, and she just walked to it.

Correction: The part where she descends to the other car is not shown, but it is implied.


Corrected entry: When sitting in the hall and eating ice cream, look how far she is away from the cups - but a blink later she slightly reaches over the table and gets a spoonfull.

Correction: The shot from behind Ellie shows one tub that is definitely close enough for her to reach considering the manner in which she leans forward. It even has a spoon ready in it.


Corrected entry: In the last scene where they all get in the helicopter everyone is dirty, sweaty, and bloody. Then a few seconds later in the helicopter. Ellie appears to have showered and combed her hair in the past few minutes.

Correction: Not sure about this one. Her face wasn't dirty in the first place, and she appears to have simply run her fingers through her hair. Remember, she didn't spend the night in the jungle or traipse across the whole island.


Corrected entry: In the scene at the very end when everyone's getting on the helicopter, Ian's left leg is bandaged. Then, once he and Hammond are behind the helicopter door, Ian's right leg is bandaged.

Correction: Ian's leg is only seen once during this final scene, and it is his left leg which is bandaged the whole time.


Corrected entry: Malcolm, Grant and Ellie are in the same car, but when Ian talks to Hammond through the camera you can see that Grant is not sitting in the back seat. In the next scene when Malcolm sits down again Alan is sitting there.

Correction: You can see for a couple of frames the Grant IS in the explorer (though mostly hidden by Malcolm's head filling the camera view), but he is sitting in the boot area so that he can look out of the furthest-back side window. Whilst Hammond is saying "I really hate that man", Grant climbs back into the seat, then we see him put his hat on.


Corrected entry: When they are all first taking a trip around the park in the jeeps, they come across the Triceratops lair. Alan jumps out, leaving the door open, Ellie follows very quickly, but when she leaps from the car, you hear two car doors shutting, how was she able to shut both in mid jump?

Correction: As she gets out she leans on the rear door and shuts it, then closes her own door. There is enough time for her to do this.


Corrected entry: During the computer guy's dash for the boat, he crashes a Jeep Wrangler and decides to use the front winch. The sequence shows the Jeep stuck on a downhill in slippery conditions. In order to stop a moving vehicle that way, he would have to be hung up on something solid enough to halt a 20mph+ 3800lbs vehicle cold. The winch was most likely in the 10,000lbs range. The combination of the two would have caused severe damage to either the Jeep or the winch cable. Other than getting the fat man out of the car, it doesn't make much sense.

Correction: Nedry wouldn't have had any idea of the capability of the winch. He was just in a hurry to get out of there, so wouldn't be thinking about damage to the jeep.


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.

Correction: During the kids' eating session, there is plenty of time for the static in his hair to die down a bit, and for him to flatten it down himself. It doesn't become THAT neat.


Corrected entry: When Hammond first introduces himself to Drs. Grant and Sattler in their trailer, he pops a bottle of champagne. Ellie Sattler begins to frantically wash out a dirty set of tumblers that were in the sink. However, a clean set of wine glasses are visible on the cabinet above her.

Correction: Ellie is surely too flustered by the arrival of their biggest contributor to be thinking about where the clean glasses are, so grabs the nearest thing and starts to wash it up.


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.

Doc Premium member

Correction: We don't know that Hammond is not going to do that. Having to convince the investors is just the first step. Without financing, nothing else matters because the park will never open.

wizard_of_gore Premium member

The park is all but finished. You convince investors at the beginning, inspectors at the end. Convincing investors after the fact is just not how it works. Thinking about what the security inspectors will ask at the end is equally bad practice, although I have seen it done that way, if not quite at that scale.

The whole manual reboot had to be done because Dennis Nedry locked them out of the system, so they had to do a hard reboot. Dennis Nedry's virus and meddling also shut the fences down intentionally. In practice the reboot would be done with more time on their hands and someone at the compound ready to reboot quickly enough that all fences go back online in time. In this situation however, they didn't have those luxuries. No system can be fully made failsafe from industrial sabotage or hacking.


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.

Correction: An electric fence designed to stop things jumping into and climbing it would have alternate rails electrified with opposite polarity, or AC current with the opposing phase, resulting in exactly this effect. So, while people often object that it doesn't act like a cattle fence, this is only because cows can't jump or climb, and cow-fences are typically a single rail.

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.

Charles Austin Miller

Correction: There's not really a whole bunch of proof that this is valid. As we saw, the freezer floor was covered in ice, which would have negated some of the Raptor's momentum. The kids could have closed it. In the other case, there was no ice on the floor, so the Raptor had full swing.

But even so if the raptor did slip on the ice going into the door it would still send Lex and Tim flying.

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.

Correction: Time passed between those points. It is entirely plausible that he folded his stock as he walked into the thick jungle to keep it from getting hung up on the vegetation, only to unfold it again when he has his shot lined up.

An extremely unlikely situation where by he is making it harder for him to defend himself.

Ssiscool Premium member

The SPAS-12 (a shotgun, not a rifle) can be fired from the hip, as seen in a variety of videos on it. In a dense jungle, being able to swing the gun around to an up-close target without snagging would probably be more important than the shoulder stock. In fact, if you watch Muldoon swing around to try to shoot the "clever girl", the stock is in the way on his shoulder, and he couldn't get the shotgun pulled back far enough to hit her.

Correction: It's actually an Italian shotgun, the Franchi SPAS-12. From the time they pick up the shotgun to the time Muldoon extends the folding stock, you can see the folded shoulder rest still laying atop the shotgun.

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?

Correction: You assume only a single possible scenario. But we don't know that Dr. Arnold (Samuel Jackson) was pursued into the bunker by the raptor. The raptor may have already been down there to begin with when he came in. A careless park employee left the door open or the raptor opened the door itself are just two ways a raptor could have gotten in there. Even in your assumed scenario, the door could have shut any number of ways: Perhaps another of the raptors was with the first (they are pack hunters) and accidentally slammed the door shut and never figured out how to open it. Or perhaps a residual wind from the storm slammed it shut.

JC Fernandez

Corrected entry: At the closing scene on the helicopter, it is very quiet. But helicopters in operation are very noisy.


Correction: Artistic license. All the sound has been quieted for dramatic effect.

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)


Correction: Waiting for his cue is an assumption; he could have just been waiting for the first waiter to deliver his food, then get out of the way.

BocaDavie Premium member

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.

Correction: There are lots of discrepancies between the JP dinosaurs and modern paleontological studies of dinosaurs. Part of it can be attributed to genetic manipulation, and part of it is attributed to a possibly false understanding of dinosaurs (since it's entirely based on an ever-changing interpretation of the limited fossil record). For instance, according to the film, no one knew dilophosauruses were venomous until JP bred them. Since there are no actual living dinosaurs to dispute the movie's portrayal of their behavior and appearance, it's not a mistake, so long as it remains consistent within the fictional world the movie creates.

Jurassic Park mistake picture

Revealing mistake: In the scenes where there's a video link to the docks shown on computer, there's a bar moving along the bottom of the screen, showing us that it's actually a video that's just playing on the computer. (00:52:05)

John Hammond: All major theme parks have had delays. When they opened Disneyland in 1956, nothing worked, nothing.
Ian Malcolm: But, John, if the Pirates of the Caribbean breaks down, the pirates don't eat the tourists.

Trivia: The T-Rex roars are a combination of tiger, elephant, alligator, whale, and dog sounds.

Question: Was there any truth to Hammond's comment that none of the rides at Disneyland worked when the park first opened? I just find that a little hard to believe.

Gavin Jackson

Chosen answer: Yes. The first opening day of Disneyland in California was catastrophic. The pavement was fresh and the sun was so hot high-heeled shoes actually sunk into the walkways. Counterfeit tickets were made, resulting in more people than the park had room for. They ran out of food and drinks. Bathrooms clogged and shut down. Many of the rides broke down on opening day. The Storybook Land Canal Boats had to be pulled by cast members in rubber boots. At the time, there were no guide rails for Autopia; some of the cars crashed into each other, making them inoperable. A gas leak in Fantasyland lead to the land being temporarily closed for part of the day.
