Jurassic Park

Corrected entry: In the jeep, just after they arrive on the Island, the lawyer says "If they're not convinced, then I'm not convinced" when referring to the financial insurers he was referring to. Of course, what he should have said was "If I'm not convinced, they're not convinced".

Correction: He's referring to the experts on the island, like Malcolm and Dr. Grant - he's not knowledgeable enough, but is going to trust their opinion.

Corrected entry: When the t-rex is running after Malcolm, Ellie and Robert, it shouldn't take them so long to go faster than 30 mph (which is what John Hammond mentioned earlier in the film that they had clocked the t-rex at). If you really need to, you can go to faster than 30 mph in less than 20 seconds (depending on how fast you can get the revs high enough to change gear), so why does it take Robert a minute or two? He should have been away from the t-rex before Malcolm went anywhere near the stick. Considering there's a massive monster ready to eat them, wouldn't you be speeding away as fast as the jeep will go? Even conceding a muddy road with trees on either side - they are in a four wheel drive jeep and the trees would shield the road from much of the rain, making it not quite as muddy as the earlier shots when the t-rex attacked. The jeep is built for these types of conditions, plus Robert (the driver) has been all over the world tracking animals; there is no doubt he has been driving jeeps in all sorts of weather and would be quite an expert at it.


Correction: Firstly, it doesn't take 2 minutes to get away from the T-Rex as you describe. And it is doubtful that Muldoon's experience at driving jeeps extends to being chased by a T-Rex that became extinct 65 million years ago.


Corrected entry: Grant says that he and the two kids need to climb over the electric fence. So to check if the power is off to the fence he throws a stick at the fence, most people would know that wood doesn't conduct electricity, therefore even if the power was on it still would have just bounced off.

Correction: It was just an act to try and scare the kids. Grant looked up at the fence before throwing the stick and saw the light on the fence was off indicating the power was down. He then acted like he was checking the fence using the stick and then scared them by grabbing the fence and pretending to be electrocuted.

Corrected entry: There's a problem with the "faulty lysine gene" idea. If the idea is to insert a faulty gene to prevent the dinosaurs metabalizing lysine, then feeding them dietary supplements won't help. They won't be able to metabolize the extra lysine, so what's the point of them eating it? If the idea is to stop them manufacturing lysine then they are on a hiding to nothing anyway, as lysine is not "manufactured" in the body and is obtained exclusively from dietary sources. Either way, those dinosaurs are in trouble from the getgo.

Correction: The faulty lysine gene wasn't inserted to prevent the dinosaurs from metabolising lysine: It makes them lysine dependent. Word for word from the book (since it explains it better): "we don't want them to survive in the wild. So I've made them lysine dependent. I inserted a gene that makes a single faulty enzyme in protein metabolism. As a result, the animals cannot manufacture the amino acid lysine. They must ingest it from the outside. Unless they get an extraneous source of lysine - supplied by us, in tablet form - they'll go into a coma within 12 hours and expire."


How is it even possible to administer tablets to a dinosaur?

Depends on the dinosaur. With a T-Rex, just get another animal such as the goat and put the tablets in the body of the goat. Same way you put a dogs tablet in a bit of ham.

Correction: Lysine could be administered by making vegetable matter high in lysine available.

Corrected entry: Watch carefully as Ellie removes her protective gloves after examining the um, droppings. To properly remove soiled gloves, one should "peel" the first one down from the top, turning it inside out. Hold the removed glove in your other hand, and "peel" the second glove down, turning it inside out and encasing the first glove. This prevents your hands from becoming contaminated. Ellie removes her gloves by pulling the first one off at the fingers, keeping it soiled side out. She then grabs the other glove, removes it the same way, then holds both of them together in her right hand, thereby ensuring nice, dinosaur-poopy hands. (00:51:00)

Correction: OK not pleasant and a strange choice, but not a mistake and definitely not a factual error to decide to remove gloves in this fashion.


Corrected entry: When Tim is holding onto the fence, when the power came on, it would cause his hand muscles to clench the cable.

Correction: You haven't been electrocuted before. Otherwise, you would know that a powerful electric shock will knock you backwards by several feet.

Depends on whether it's Alternating Current, which would do as the original mistake says, or Direct Current, which would do the second option, like the correction. Insufficient information is given to say solidly which the fence uses.


We can reasonably assume that Jurassic Park was using Direct Current, wisely intended to repel the dinosaurs away from the fence line. If it was Alternating Current, then the multi-billion-dollar menagerie of ultra-rare specimens would be fried to a crisp (or at least seriously injured) on a daily basis, as they would be unable to release the charged fences. Therefore, Direct Current is the only fiscally-logical choice (and it explains Tim being repelled from the fence).

Corrected entry: Right before the scientists see the dinosaurs for the first time, Ellie is looking at this plant leaf and saying, "This has been extinct since the ____ period." If it's an extinct plant, how could they duplicate it? Mosquitoes don't drink chlorophyll - there's no way it could have been preserved if everything worked the way they said. No organic material from an extinct plant from either the Jurassic or Cretaceous period has ever been found, and given that plant material decays very quickly, it never will be. The engineers did not use some magical "other method" to clone plants because there aren't any.

Correction: As has been pointed out on this site before, inventing deux ex machina explanations for plot holes and factual errors does not invalidate them. No organic material from an extinct plant from either the Jurassic or Cretaceous period has ever been found, and given that plant material decays very quickly, it never will be. The engineers did not use some magical "other method" to clone plants because there aren't any.

Correction: The video they watch (with Mr. DNA) only explains how they recreated the dinosaurs, which were the main attraction of the park. The engineers used other methods to make the right environment for the animals, but as it's not half as exciting, the viewer never finds out exactly how.


Correction: Mosquitos do not drink from plants, but it's still possible for a piece of a leaf to get caught in amber. This would be just as viable as DNA in the blood in a mosquito.

Mosquitos do not drink from plants? Are you joking? All male mosquitoes - every single one of them - feed exclusively on plant sap. While this is irrelevant to the posting it invalidates your correction.

Correction: The simplest and most likely explanation, once you accept the logic of this movie in the first place, is that the engineers are removing Plant DNA directly from the amber.


Amber is fossilized tree sap, anything fossilized doesn't hold any DNA. However, it is possible amber holds trapped plant parts (called 'inclusion'), from which DNA can be extracted. Theoretically.


Corrected entry: In the scene where Sam Neill and the little boy are climbing down the tree, the car keeps crashing down a few branches at a time behind them. Why are they in such a hurry? If the car is falling in such a straight line, wouldn't it be easier to climb around to the other side of the tree, where they would be safely out of danger? (01:14:00)

Correction: If you pay attention, as they are climbing down the tree there are no branches within reach that aren't in the path of the falling truck. They would have to go out to the ends of the branches to climb around and that far away from the trunk the branches might not hold their weight. The quickest, safest way down is to outrun the falling truck.


Corrected entry: Ellie locks the outside handle of the freezer with the steel pin, but somehow the second raptor gets out.

Correction: You're confusing two of the raptors here. Ellie locked one in the electrical area, but there may yet be another way out. Lex locked the one in the freezer, which is probably dead after that. There was still the third raptor there.


Corrected entry: In the last scene, the helicopter is shown out at sea, yet the intercuts of the interior show a mountainous green background close by.

Correction: The exterior shot of the helicopter leads straight to the end credits of the film and fade to black; there are no intercuts to the interior. The previous shots of the interior show trees on the right side of the helicopter while Grant sees the birds flying over the ocean from the leftside windows, indicating that the helicopter is flying along the coast of the island. We cannot see the island in the exterior shot because the shot is from the perspective of the island (from the helicopter's right side).

JC Fernandez

Corrected entry: In the scene where the lawyer is running to hide in the bathroom, you can see a rock sign near the bathroom. When Malcolm is running from the Tyrannosaur, the sign is gone. (01:00:55 - 01:04:40)

Correction: The rock is there in all the shots in "The Ultimate Collection" DVD box set version, but it is only visible briefly in Dr. Malcom's shot.

Oliver Hunter Premium member

Corrected entry: During the beginning when the gatekeeper falls when he lands on the ground you can see behind him the light on the lock is already red. In the next shot you see the locks lights going from green, to yellow, and to red again. (00:02:30)

Correction: It looks more like a red lens flare spot than the lights on the doorway. In slow motion the red spot can be seen in front of Jophery, which wouldn't be possible if it was the light on the door.

Corrected entry: In the scene where the characters have fallen from the hanging T-Rex fossil and are being surrounded by velociraptors, the camera views across the room showing nothing at all and then back to the velociraptors. Then it swings back and T-Rex just appears out of nowhere and saves the day by eating one of the velociraptors. How did it get in? We just saw there was nothing there, and they've already elaborated about how much noise a T-Rex makes when it's close, the water ripples, the shaking, and pure noise.

Correction: Previously submitted and corrected entry.


Corrected entry: During the scene with the T-Rex attacking the Explorer 04 the hood level fog lights are off. After the Rex flips the Explorer onto and over the edge the fog lights are on.

Correction: Already submitted, complete with timecode.


Corrected entry: If you play the film in slow motion just as the Dilophosaurus opens its frill for the first time, you can see that it is folded around the puppet's neck like an umbrella instead of being skin-tight and indistinguishable as it was previously.

Correction: Even in slo-mo, this was hard to see, thus disqualifying this per the rules of this site. Furthermore, it looks flawless at normal viewing speed.


Corrected entry: With some of the electric fences it seems that the wires enter the bushes and just disappear. If the fence wires really do continue, we would surely see more columns appearing in the bushes.

Correction: Already submitted entry, complete with screenshot.


Corrected entry: When Timmy is near the top of the fence, just before the electricity turns back on, he has his head and shoulders through the fence, with the wires resting against his armpits. Since the shoulders are the widest part of the body on a person of normal weight, a hole wide enough for your shoulders is wide enough for the rest of you. The spaces in the fence are somewhat circular--they are at least as tall as they are wide--so why is Timmy climbing the fence in the first place? He could have just crawled through at the bottom! (01:39:10)

Correction: At first glance, this is correct. Timmy could fit through the fence wires that are CLOSE TO THE TOP, but earlier when the characters are standing at the base of the fence you see Grant put his face practically touching the fence while he's attempting to make the hole larger and its clear that his head wouldn't stand a chance of fitting thru the hole and i seriously doubt that his head is larger than a ten-year old's shoulders. A possible explanation: the fence they are climbing is labeled as perimeter fence, so likely the holes are smaller at the base of the fence to prevent the small dinos from escaping, but the holes become larger as the fence becomes taller to save on materials a bit as the small dinos obviously couldn't get high enough up on an electrified fence to get through a larger hole towards the top.

Very well, but fact of the matter is, Somewhere on that fence, Timmy could have slipped through, and saved himself from having to climb all the way to the top, saving time, energy and at least some of the risk of climbing to great height.


Corrected entry: In the scene where Nedry falls off the waterfall, the jeep rope in his hands is gone, but when Nedry stands up, the rope is back.

Correction: He scoops the rope up just as he stands up.

Corrected entry: When the raptors open the lever handle doors, (like going into the kitchen) the handle on the opposite side moves too. With these types of doors, only the handle with the pressure applied to it moves, not the other side. This was added to show the raptor's claws on the door handle.

Correction: I've seen plenty of lever handles where the two handles are directly connected. And even if it had never been seen before, there's no reason to say it couldn't be done. It is, after all, easier than keeping the two handles independent.

Corrected entry: On their way to the island, Hammond is sitting on one side of the helicopter, and the lawyer on the other side. The direction behind the lawyer was toward the island. The lawyer looks out he window on the right side of the lawyer. He looks straight while he can't see what is behind him. Then Hammond looks out the same window in the other direction that the lawyer did not look at. Hammond then says, "There it is." How did the lawyer see the island is his position?

Correction: This is wrong. Gennaro is facing TOWARDS the island, and Hammond looks sideways to see a different part of the island out of the other side of the helicopter. They would both have been able to see it, because it is a large island and they were close to it.


Jurassic Park mistake picture

Continuity mistake: When Tim and Lex first arrive, Lex is wearing a purple tank top with a colorful design, and in the following scenes or even between consecutive shots her tank top changes to completely different designs, though it's the same style of tank top.

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.
