Jurassic Park (1993)

Revealing: In the scenes where there's a video link to the docks shown on computer, there's a bar moving along the bottom of the screen, showing us that it's actually a video that's just playing on the computer.

Continuity: When the tour trucks are stopped outside the Tyrannosaurus Rex paddock, we are shown a goat in a cage (inside the paddock) that appears to be at the same level as the road (outside). However, when Dr. Grant and Lex go over the wall, the ground is several stories down. This is because the ground along the paddock side of the fence is not level. The tour cars are brought alongside the top of a hill in the T-Rex paddock.

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.

To make the water in the glass on the dashboard 'jump', they strung a guitar string from the underside of the dashboard to a bolt on the floor and then plucked the string.

The T-Rex roars are a combination of tiger, elephant, alligator, penguin, and dog sounds.

In the original script, the T-Rex didn't save the people at the end. Grant shot one of the raptors and the other was killed when he got crushed under the dinosaur ribcage bone. Steven Spielberg thought the audience would hate him if he didn't bring in the T-Rex again.
