Continuity mistake: When Nedry meets Dogson he cries "We've got Dogson here!" with the green napkin bundled inside his fist. From the opposite angle a big chunk is standing out.
Continuity mistake: Tim is trying to remember the Gallimimus, and we see a shot of him from behind with both arms down. In the opposite shot his right arm is up as he guesses the name.
Continuity mistake: When Hammond meets Grant and Sattler in the trailer he dries the glass with a white tea towel in his hands. A shot later it's pink. (00:11:32)
Continuity mistake: When Dogson talks to Nedry about the bribe, Nedry's hand on the suitcase changes in every shot.
Continuity mistake: When the movie begins a worker on the top part of the crate falls to the ground, face down. A split second later he's facing upwards.
Continuity mistake: When Grant covers Lex's mouth the dinosaur's breath blows his hat away. A shot later it's by his nape.
Continuity mistake: When Grant sees the first dinosaur, Malcolm is right behind him looking as well. The next shot is above Grant as he stands up. Malcolm has moved forward between cuts.
Continuity mistake: Muldoon lifts his gun to sight the raptor, in the next shot, he is raising the gun up and sights the raptor again.
Continuity mistake: When the gas jeeps stop for the first time they are in sunlight away from trees. At the end of the scene they are in the shade by some trees, despite them not moving in the scene. If you watch closely when Hammond tells them to stop they are in a massive patch of sunlight as shown with Dr Grant standing up. (00:21:05)
Revealing mistake: When Ellie is running to the shed, the same clip of her jumping a tree is seen.
Continuity mistake: When the T-Rex turns the upside-down car around 180°, the car's tail lights move from right to left. When Alan and Lex try to move out of the way, the tail lights are moving from right to left again.
Character mistake: Grant and Tim could simply have moved to the side of the tree instead of climbing down with the Jeep right behind them.
Visible crew/equipment: When Dr. Grant discovers the eggs in the wild, the camera comes down a tad bit too far. The operator obviously notices because the shadow of the camera creeps in along with the shadow of wires attached to it. To correct this, the shot pans up a bit.
Character mistake: When Genarro is explaining to Hammond that he is at the park to report Hammond's progress to the investors, he says "In 48 hours if they're not impressed, I'm not impressed. We'll shut you down, John." He should have said "If I'm not impressed, they're not impressed" since the investors would be shutting down the park on his advice, not the other way around.
Suggested correction: He'll be the one to shut it down, not the investors. They gave him the ability to do that. So once he hears they are not impressed, he'll be shutting it down.
That still makes the statement backwards, since he is representing the investors interests, not his own. The way he words it suggests even if they weren't impressed but he was, he could keep the park open of his own accord. The buck stops with the investors.
There's actually already a submission just like this one in the Corrections section, with the correction - provided by JC Fernandez - noting that Genarro is referring to the scientists that have to be convinced that the park is ready to open, and that if the scientists aren't convinced, then Genarro will not be convinced either, and he will notify the investors of it.
Didn't see that correction before. When reviewing the scene in question Genarro does ever so slightly gesture behind himself when he says "they", which I had not noticed before.
Continuity mistake: After the kids greet their Grandpa there's a shot outside of them waiting for the cars. The boy stands ahead of the girl, who's a meter behind. A shot later he has moved 5 meters behind.
Continuity mistake: The first time the cars arrive the girl walks to the rear passenger window and peeks inside. In the close-up she is meters behind repeating all of the movements.
Continuity mistake: In the tree, before Lex tries to feed the dinosaur there are no branches or leaves in front of her. She leans forward and a shot later a branch filled with leaves has magically appeared by her waist in a mere nanosecond. This keeps changing back and forth depending on the angle.
Continuity mistake: When Grant is feeding a dinosaur in the morning he is either holding the food with one hand or two depending on the shot.
Continuity mistake: When the kids and Grant wake up in the tree Alex covers her ears, but a shot later her arms are down by her side.
Continuity mistake: When the baby dinosaur is born, Grant's arm swaps from bent to extended between shots. (00:00:25)
