Revealing mistake: When Nedry is attacked by the Dilophosaurus, (the spitting dinosaur), the first spit supposedly lands on his shirt, BUT if you look closely, Nedry slaps it there himself with his hand - there's only a little bit on his shirt before he hits himself, then there's loads. (01:10:40)

Revealing mistake: When the Explorers are entering the park through the large wooden gate, during the overhead angle you can see that the perimeter fence isn't continuous. (00:40:00)

Continuity mistake: When the baby dinosaur is breaking the egg, the eggshell is almost open on one shot, and starting to break with a different shape, in the next shot. (00:27:35)

Sacha ★

Continuity mistake: When Lex and Tim are in the car and the T-rex is attacking them, at one point the T-rex smashes through the roof of the car and the clear roof falls through on top of Lex and Tim. The T-rex breaks it with her teeth, but in the next shot it's whole again. (01:03:20)

Continuity mistake: When we first meet the dinosaurs Alan is sitting in front of a lake. Ellie is standing right in front of him. After the cut Ellie comes to Alan from behind and puts her hands on his shoulders. (00:21:25)

Continuity mistake: Before the vehicles leave the compound Lex says to Grant, "She said I should ride with you cuz it'll be good for you." In this shot, Ellie's door on the second car is open with Malcolm talking to her. In the next close-up shot of her, the door is closed with Malcolm gone. (00:38:40)

Continuity mistake: When Grant and Malcolm's car suddenly "just stops" you can see outside that they are in a thick dense jungle area. A few minutes later, the two parked cars are in a wide open area next to the T-Rex fence. (00:55:20 - 00:58:10)

Continuity mistake: Just before the Tyrannosaurus Rex escapes from its pen, it drops a goat's leg on Lex and Timmy's car. When it comes back to attack them, the leg is gone. Then it appears and disappears. (01:00:25)

Continuity mistake: Just after Timmy puts the goggles on and climbs into the back with Lex she says, "don't scare me" and turns to face him as he crawls into the boot. In the next shot she is immediately facing in completely the opposite direction, looking through the window. This is just before Timmy says, "oh cool, night vision". (00:58:35)

Continuity mistake: When the T-Rex is approaching, the lawyer runs into the bathroom stall and the roll of toilet paper is mounted horizontally. After Ian runs towards the bathroom away from the T-rex, in the shot of the panicked lawyer as he shuts the door the toilet paper is now mounted vertically, but when the T-Rex knocks down the stall walls, leaving the lawyer sitting out in the open, it is again mounted horizontally. (01:00:50 - 01:04:45)

Continuity mistake: When Hammond watches the vehicles leaving the visitor center the first car is passed the main steps. In the next shot of the car, they are just moving past the steps. (00:39:30)

Continuity mistake: In the badlands segment of the film, after Ellie, Alan, and Hammond enter the trailer. Hammond decides to open the bottle of champagne that Ellie, and Allen were saving. Hammond begins to buff a couple of glasses with a towel that magically changes to a pink towel in the next shot. (00:10:45)

Continuity mistake: At the start of the Badlands sequence, the palaeontologists are brushing-out a dinosaur skeleton. In the close-up shot, they are working on the head (someone 'picks its nose') and one of them has a red-handled brush. When we cut to a wide shot, there is only one person working on the head (the nose is still being brushed) and there is no red-handled brush in sight. (00:05:30)

Continuity mistake: Hammond pours champagne into his glass and it's full of foam. After Grant says his line, when Hammond says, "...for the next three years." the foam is all gone. Foam from champagne takes longer to disappear. (00:12:25)

Continuity mistake: When Nedry is trying out the shaving foam can, he puts some on his right hand. When the camera pans back after he's wiped most of it off on the pie, his hand is suddenly completely clean. He then pretends to wipe it off with a napkin anyway. (00:14:15)

Continuity mistake: In the opening scene Jophery is being attacked by the dinosaur in the cage and Muldoon is holding onto him while the workers shock the dinosaur. Muldoon's hat is on in one shot, then the camera cuts and it is off while the camera is dollying forward, then it is on again. This happens just as he is about to shout "SHOOT HER! SHOOT HER!" (00:03:00)

Visible crew/equipment: In the opening scene, a velociraptor is being introduced into the park from a shipping container. The velociraptor runs into the gate as it opens, knocking Jophery off the top; he falls to the ground and is attacked. As he falls, two hands come in to break his fall and prevent him from hitting the camera or hurting himself. (00:02:30)
