Continuity mistake: When President Whitmore and the rest get to Area 51, you see David Levinson in the background. Right before they go through the doors, he has a sunglasses clip over his glasses. As they start walking down the ramp, they are still on, but right after the glass doors open, you can see for a second or two the clip is off the glasses. Then when they go for a close up of Levinson, you can see him take the clip off. (01:14:55)

Continuity mistake: Steve and Jasmine are asleep and the house starts to shake. There are 3 pictures on a night stand. Two of the three fall. When they wake up the 2 pictures are back up. (00:22:20)

TiggBoy

Continuity mistake: When David is explaining to the President about the aliens' intentions with Earth's satellites, he draws two lines that start at the destroyer and go off straight both edging off Earth. But when he places the paper back on the desk to draw in the satellites, the left lines have risen away from the Earth. (00:41:00)

Continuity mistake: On the television screen that has a map of where all the ships have landed in the Eastern Hemisphere, every city is identified by name, except for Berlin, which is just identified as "Germany." (00:26:50)

Continuity mistake: When Sam Neill found the eggshells beside the root of the tree, they are on the dark soil. In the other shot, the same eggshells are on the clear sand. (01:27:40)

Continuity mistake: Just as they start going down the wire into the T-Rex paddock, in addition to the problem mentioned above with the ground level suddenly dropping, take a look at the wire. In the first shot underneath them it's curling up and towards the camera, like it's caught on something, then it changes angle, and the wire's hanging straight down. (01:06:15)

Revealing mistake: When the T-rex is attacking the vehicle and he has turned it over, the camera pans round behind the T-rex and you see through its legs, the ground all around the base of the beast is dry, but it's been pouring with rain for a while. (01:05:45)

Visible crew/equipment: When the T-Rex is knocking the car with Lex and Tim in it, he knocks it once, and then again making the Explorer flip over. If you watch carefully, you can see a big wooden pot containing one of the fake trees for the set and a stage light. This mistake has since been corrected on blu-ray. (01:03:40)

Continuity mistake: When Tim, Lex and Dr. Grant are hiding in a large tree, a large dinosaur appears. They pull some branches off the tree and feed the dinosaur. However, when they first climb the tree, there is no foliage in the area at all. (01:19:20)
