Continuity mistake: The T-rex completely destroys the outdoor bathroom facility that the lawyer ran into. The lawyer is perched atop the toilet and the remaining damaged wall behind him is tilted backwards. When the camera cuts to a shot where the lawyer is seen from behind and the T-rex is just about to eat him, the wall is missing. When it cuts back to a front shot, the wall is back again.raywest
Continuity mistake: When Ian uses water to explain chaos theory to Ellie he drops the first water droplet on Ellie's hand and she immediately begins to tilt her head to the left to follow it. The very next shot shows Ellie's head has turned to the right. (00:47:40)
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)Ssiscool
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.
Continuity mistake: When the Dilophosaur spits on Nedry the second time, it is only on his forehead and eyes. In the next shot, a second later, it is all over his face and cheeks. It was too soon for the rain to have washed it down that far.
