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

Plot hole: How did the men on the ship get killed? The bridge was intact and the T-Rex was still inside the cargo hold. [A raptor escapes from the boat when it pulls in to the harbour, but they cut the scene from the film and now that bit doesn't appear to make any sense.]

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.

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...

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.

Plot hole: Near the end of the movie, Peter Ludlow (the snivelling nephew of John Hammond who wants to create Jurassic Park in San Diego) is addressing company stockholders as they wait for the cargo ship to arrive. He says something to the effect of: "I'd like to thank you all for being intrepid enough to show up in the wee small hours of the morning." Those last six words, and the color of the sky make it seem like it is four or five in the morning at the latest. For that early, San Diego is a busy town. The busses are running, business men are out, video rental stores are open (and with plenty of customers), and generally a lot of people are out to run away from the T-Rex. I have to imagine that the mass of people running in terror (even though it is early in the morning) were put in as an homage to old monster movies. Same thing could be said for the Japanese business men.

Visible crew/equipment: When the T-Rex is running rampant in the streets, we see a guy running away from it. He tries to run into a video store, and the shot is from inside the video store. Right before that guy gets eaten by the Rex, he runs to the door to try to open it. And when this happens, you can see the reflection of the cameraman in the glass on the door walking towards it.

Audio problem: The ship is going at full speed towards the coast - making a roaring engine sound. But when it hits the coast and stops, the sound of the engines stop too. Who turned them off?

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: In the scene where Sarah is hanging from the roof surrounded by 'raptors, the position of the roof tiles she's holding on to change between shots.

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.

Continuity: The day after the T-Rex attack, when they are all walking towards the control complex, Sarah is asked about the blood on her shirt, and answers that it's from last night, but it's too humid for the blood to dry. Nevertheless all their clothes - which ought to have been soaked during the rain storm, are completely dry.

Deliberate "mistake": After Peter falls down the slope, the next few camera shots are 1st person views of the small dinosaurs which are about to attack him. The 1st shot ends a short distance from his face, at the speed which the camera zoomed in, during the 2nd shot the 1st dinosaur should have reached him. Likewise, during the 3rd shot, both the 1st and 2nd dinosaurs should have reached him, but they have not. They only reach him during the overhead camera shot.

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.

Character mistake: Sarah is a trained expert with predatory animals. Yet when her jacket is covered with blood (and not just any blood, the blood of the infant t-rex), and they're in a forest surrounded with carnivorous dinosaurs, and she knows that they need to pass through velociraptor territory, and she thinks that the t-rex might follow them, she doesn't think to take the jacket off. And the others, who also happen to be hunters who would surely know that the blood would attract predators, don't say anything about it.

Continuity: Near the end of the film, when Drs. Malcom and Harding are looking for the baby T. Rex in San Diego they arrive at the new InGen Jurassic Park. The car brakes hard, skids a little pulling a trailing cable for a portable light. the lamp falls. When they get back into the car with the baby T. Rex, to use it to entice the mother back to the ship, the lamp is standing again.

Continuity: When they're in the shack, and the raptors are making the walls shake, something like an animal's muzzle falls off the wall and lands in front of the door. We then see a closeup of the raptors starting to dig under the door, and there's no sign of the muzzle. We then cut back to a wider shot of the door, and the muzzle's back there again.

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.

Visible crew/equipment: In the scene in the shed towards the end, when Sarah and Kelly are at the top, you can see the harnesses that are keeping them safe.

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.

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.
