Scenes of the T-Rex attacking Grant and the kids while they ride down a river and through a running waterfall were cut before filming.
The full-sized animatron of the tyrannosaurus rex weighed about 13,000 to 15,000 pounds. During the shooting of the initial T-rex attack scene that took place in a downpour and was shot on a soundstage, the latex that covered the T-rex puppet absorbed great amounts of water, making it much heavier and harder to control. Technicians worked throughout the night with blow driers trying to dry the latex out. Eventually, they suspended a platform above the T-rex, out of camera range, to keep the water off it during filming.
Newspaper clippings on the fridge in Grant's trailer read "Space Aliens Stole My Face" and "Dinosaurs On Mars!"
In the original script, the T-Rex skeleton in the lobby was hooked up to pulleys like a giant marionette. In the ending, Grant was going to man the controls and act as puppeteer, using the skeleton's head and feet to crush the raptors
When Dr. Grant is talking to the boy in the beginning of the movie, there is a dinosaur's head depicted on the mountain in the back.
Michael Crichton always intended John Hammond to be "a dark Walt Disney".
The Mr DNA cartoon was Steven Spielberg's way of condensing much of the novel's exposition into a few minutes.
Two scenes from the book were removed from the film: an opening sequence with Procompsognathus attacking children because Steven Spielberg deemed it too horrific, and for budget reasons, a sequence with the T-Rex chasing Grant and the children downriver, before being tranquilized by Muldoon. Both sequences were reworked for the sequels. |
