After making this movie, Ariana Richards developed a great interest in dinosaurs, and assisted Jack Horner (paleontologist advisor for the film and the inspiration for the Dr. Grant character) on an actual dinosaur dig in Montana the following summer.
Generally speaking, any shot of a full dinosaur was computer-generated, but shots of parts of dinosaurs were of animatronics.
Richard Attenborough's first acting role in 15 years.
Grant and Sattler unearth a Velociraptor skeleton in Montana early in the film, and later encounter live Velociraptors that are about the size of a full grown human. In reality, Velociraptors were not even half the size of the animals seen in the film, and their remains have mainly been found in Asia, never in Montana. The species identified as Velociraptor in the film is actually more consistent with Deinonychus. When Michael Crichton was doing his research, he used the book Predatory Dinosaurs of the World by renowned paleontologist Gregory Paul, in which he had proposed that Velociraptor and Deinonychus were species within the same genus. This theory was abandoned by the time the movie was made, but the names for the film weren't corrected.
A baby triceratops was built for a scene where one of the kids rides it. Special effects technicians worked on this effect for a year but the scene was cut at the last minute as Steven Spielberg thought it would ruin the pacing of the film.
Perhaps to increase the general sense of anxiety (if only subconsciously), the Triceratops mural behind Hammond as he eats ice cream in the visitors center also incorporates elements from "Guernica," Pablo Picasso's famous painting of the horrors of war. |
