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.
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!"
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.
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.
Factual error: In the early scene where Dennis Nedry meets a man to plan the embryo theft, the subtitle says that they are in San Jose, Costa Rica. However, the sleepy coastal town in the movie bears no resemblance to the real San Jose (a cosmopolitan capital of almost 1 million people, situated 50 miles from either coast).
