The Lost World: Jurassic Park (1997) - 43 mistakes

Continuity: At the very beginning, when you see the English family on the beach, the little girl wanders off and you then see a shot of her on her own. However, she must have walked a pretty long way because the beach she is on is definitely not the beach that her parents were on; the rocks in the ocean are gone and the waves are smaller.

Continuity: When the English family arrives at the island, the sky is a bit gray. When the little girl wanders off, it is suddenly a sunny, beautiful day.

Continuity: In Hammond's bedroom, Ian distinctly asks, "And who are these four lunatics that you're trying to con into this?", before Hammond states the specific number in the team. This is backed up by the subtitles.

Visible crew/equipment: When Ian is talking to John in the bedroom you can see a mirror. After John tells him about the project, the camera moves to the bed and there is a reflection of blue jeans, probably the cameraman's.

Continuity: When Ian starts to walk out of Dr. Hammond's office, we see an empty hallway. A shot or two later, there is a butler standing to the left of a lamp in the middle of the hallway. Then another shot or two later, the butler is standing to the left of the hallway where we can't see him.

Continuity: When Jeff Goldblum is giving his daughter the news about him going away for a few days, he gives her a piece of paper with someone's number on it.  However, in the next shot Jeff has the paper back in his hand.

Continuity: Towards the beginning where the girl goes to photograph the Stegosaurus, the scene cuts back to her boyfriend and the guy with the video camera.  In two cuts to their scene while the girl is photographing and interacting with Stegosaurus, the guy with the video camera opens the flip out LCD on the video camera and starts shooting the action.

Revealing: In the beginning of the movie, when the rescue group arrived on Isla Sorna, the actress grabs the Nikon F5 of the photographer and makes her way to the nest of the Stegosaurus. After several shots of the small Stegosaurus there is no more film left in the cassette, so the camera begins to rewind it automatically. The thing is, you never see the rewind knob moving although you hear the camera's motor rewinding (The Nikon F5 has a manual rewind knob to be able to rewind the film when the batteries are dead). There was obviously no film at all in the camera.

Revealing: When the stegosaurus begin to move around a lot, you can see the one that is charging at her steps in the creek water, but there is no splash or any ripples.

Continuity: When Sarah, Malcom and his daughter argue in the trailer for the first time you can see out of the back window. It shows they are right in front of a thicket of trees a few feet behind the trailer. When they step outside a minute later to see the InGen choppers arrive you see that the trailer is pulled up on the cliff tops already. The only view you should have seen out of that window was open sky as the window points out to sea.

Other: When they're on the island and the INGen helicopters are flying in, Jeff Goldblum takes the binoculars and looks through the wrong end.

Continuity: When the second INGEN team is rolling through the open field and you first see Rolland talking to Peter about not setting up camp on the game trail, if you look carefully in the shot looking at Peter they are actually on a paved road instead of open field. Split second mistake.

Continuity: When Rowland and the other man spot the baby T-rex, it is eating its meal. Then it looks up at them. Then it cuts to another shot where Rowland and the other man are talking. If you look in the background you can see the baby with his head down eating again. Then it cuts back to where the baby is. It is looking up at them again.

Visible crew/equipment: When Sarah and Nick return to the trailer with the baby T-rex, there is a shot of Nick carrying the rex towards the operating table. Look between the baby rex's legs - there are a series of wires leading from a opening in the anamatronic dinosaurs belly to a bulky device (presumably a battery pack) in the actor's pocket. Once you know where to look for the wires, you will notice them in many other shots in the film when various actors are holding the baby rex.

Continuity: In the scene where Sarah is helping the baby T-rex in the trailer and Ian is trying to dial up their ship on the radio, look at the papers Ian is holding. In one shot the back page is white, but in the very next shot, it has a red cover on the back.

Continuity: The night when the T-Rexes attack it is pouring and there is mud all over, but the next morning the grass is dry and not even in the forest is there any mud or rain puddles.

Factual error: When the vehicle is hanging off the cliff and the glass at the rear slowly begins to crack, it does so like sheet ice (or conventional window glass). Safety glass in vehicles would either be laminated (in which case it wouldn't shatter at all), or it would break into a million fragments...

Revealing: The window in the door of the trailer that got pushed over the cliff is quite obviously made of a plastic film. You can see that it is wobbling when they bang the door.

Factual error: When the first half of the trailer is hanging over the cliff, the second half is pulled towards the edge. But the pull from the first half would be going downwards - in a 90-degree angle to the position of the first half. That would not pull the second half outwards, but more lift the end up - or most likely - not pull it anywhere.

Factual error: When the trailer type thing is hanging over a muddy cliff, about to fall off, a guy drives up in a sporty little jeep, ties the trailer to it, and manages to pull the trailer back to safety. Well, at first glance this may seem okay, but that trailer was at least twice the weight of the jeep. And, if the jeep spun its wheels on the mud like that, it would lose any traction it had on the ground, thus going over the edge of the cliff with the trailer.
