Continuity mistake: In the command center, when Arnold turns all the power off, the main system VDU powers down when the 'C-1' switch is thrown (then the main 'Power' switch is turned off). However, the main system VDU comes on again when the main switch is powered on. (01:29:05)
Continuity mistake: When Alan, Lexi and Tim are climbing the hill and you see them from behind, Tim is almost next to Alan. In the next shot, when you see them from the front, Tim is lagging behind the other two and has to catch up. (01:30:25)
Continuity mistake: In the scene where Grant and the two kids start running from the Gallimimus you see a shot of them running toward the camera with the dinosaurs running around and ahead of them. In the next shot they are running away from the camera and there are no dinosaurs in front of them. There were a lot of dinosaurs in front of them, where did they all go? (01:31:05)
Character mistake: Hammond talks about all the things that went wrong when Disneyland opened in 1956. Disneyland actually opened in 1955. (01:32:10)
Revealing mistake: When Ellie runs from the Raptor the stunt double who runs for her has on a wig that looks nothing like her real hair. It just looks very fake. (01:35:00)
Continuity mistake: When Alan and the kids are about to climb the fence, when he throws a stick at the fence, his hair is messed up, it is sunny and windy. In the next scene his hair is perfectly fixed and it is shady, and it is not windy. (01:36:10)
Revealing mistake: During the scene where Dr. Grant and the children are forced to climb a fence to flee from an unseen dino, there's a brief side view of the fence that clearly shows that it isn't continuous - it is probably only about 75 feet wide. (01:36:35)
Continuity mistake: When Tim is up the fence Grant starts counting for him. When he starts to count, Lex and him are next to the fence. In the next shot, Lex and him are much further away from the fence. (01:38:55)
Revealing mistake: When Tim is shocked off the fence as the power comes back on, the sparking effects are not where his hands are touching, instead the sparks are several inches away. (01:39:00)
Continuity mistake: After being electrocuted, Tim flies down vertically, but Dr. Grant catches him horizontally. (01:39:15)
Revealing mistake: In the shot immediately following Ellie turning on the circuit breakers when the raptor attacks her, we see a light bulb touching its head. There is smoke appearing where the bulb is in contact with the raptors head, the power has been off for a while the bulb would not be that hot after being on for just a few seconds. (01:39:35)
Continuity mistake: After Ellie injures her foot running from the raptor, her limp switches legs repeatedly for the rest of the film. (01:40:10)
Continuity mistake: In the scene where the park ranger is about to shoot the raptor with his shotgun, we see him unfolding the butt of the gun. As he does this he places the butt under his arm. As the camera angle changes, he has the butt pressed fully against his shoulder. (01:40:50)
Continuity mistake: When Grant is taking the two children back to the visitor center ("Big Tim, the human piece of toast") Tim's ear is perfectly clean. In the next scene, the children are eating cake when suddenly a raptor's shadow appears on the wall; Tim's ear is covered with blood. Next scene with the hide-and-seek with the raptors in the kitchen you can see the same ear several times and it is perfectly clean. (01:41:40 - 01:45:40)
Continuity mistake: When Ellie is turning on the circuit breakers she turns on "Herbivore Feeding Compound", "Visitors Cntr. Compound", "Visitors Cntr. Control Rm", and goes to press "Visitors Cntr. Tour". In the next shot of her she presses "Visitors Cntr. Control Rm." and "Visitors Cntr. Tour" again. (01:42:55)
Continuity mistake: When the two kids are eating the food just before the raptors try to attack them, the little boy's hair is all messy and strands of it are sticking out. In the next scene, when the kids run into the kitchen and hide behind the counter, his hair is perfectly straight and combed. (01:43:30)
Visible crew/equipment: In the kitchen scene, when the raptor appears in the small window. You can see movement (possibly a reflection of a camera person's arm) on the surface of the door, right below the window. (01:43:45)
Visible crew/equipment: Watch carefully the scene where the raptors enter the kitchen (that angle where you can see almost the whole kitchen while raptors are coming in from the far away door). As the first raptor enters the kitchen, you can see someone grabbing its tail to hold the puppet-thing steady. (01:44:40)
Revealing mistake: When Lex and Tim are playing hide and seek with the Raptors in the kitchen, when the camera cuts to a wide shot of the Raptors walking in from a distance, the Raptor on the left looks directly at Tim while he crawls by, but then looks back in the direction it was going. (01:45:15)
Visible crew/equipment: When Lex & Tim are hiding from the two raptors in the kitchen, a ladle (a soup spoon) by Tim's head falls to the floor and attracts the attention of the raptors. If you watch the top of the ladle right before it falls, from the right you can clearly see the shadow of the device that causes it to turn and fall. (01:45:55)
Chosen answer: They all left on the same boat Nedry was trying to get on with the embryos. You can hear Samuel L Jackson's character announce that the boat will be leaving at a specific time and everyone had to be there or be left behind.
