John Hammond has developed a dinosaur park (in a very remote Island) using a DNA of a prehistoric dinosaur taken from an ancient insect. In a tour that Hammond makes to a selected audience which suppose to decide whether the park is safe or not safe for public, the security system collapsed, and the dinosaurs set themselves free.
As Dr. Alan Grant, is the primary protagonist of Jurassic Park, he is a professor of paleontology at the University of Denver who became famous in the eighties for his field research on fossilized dinosaur
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.
In the egg-hatching scene, a new-born baby triceratops was originally supposed to come out of the egg, but it was changed to a velociraptor.
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.
