Much of the behavior seen in the film is based on modern wild animals, since little is known of the actual behavior of dinosaurs.
Richard Attenborough plays Joseph Mazzello's grandfather. He subsequently cast Mazzello in his next film, Shadowlands (1993).
The tyrannosaur paddock set was constructed both on location and as a studio set. The former was for the daytime scene in which the creature fails to appear, and the latter for its nighttime escape, in order to accommodate Stan Winston's robotic t-rex. This set required a soundstage much bigger than Universal had to offer, so it was filmed at Warner Bros.
According to Foley Artist Dennie Thorpe, the sounds of the hatching baby dinosaurs were created by a combination of crushing ice cream cones (egg shell breaking), squishing cantaloupe melon halves (embryonic emergence), goo-smeared pineapple skin (baby dinosaur flesh cleansing).
On the walls inside Grant and Settler's trailer are a couple of scientific skeletal reconstructions of raptors, according to how they had really been imagined in the beginning of the '90s. Interestingly, these are actually the most accurate dinosaur reconstructions on the film, having been made by paleontologist and paleo-artist Gregory Paul, whose book (Predatory Dinosaurs of the World) Michael Crichton studied when writing the original Jurassic Park novel. One of the papers on the wall is in fact a page from Paul's book.
The park software is written in Pascal; a program is clearly visible in one of the monitor close-ups on the UNIX system. The graphical interface recognized as a UNIX system was the experimental Silicon Graphics 3D File System Navigator. The version number of the Silicon Graphics UNIX Operating System is 4.0.5 and is visible in one of the close-ups in the operating system's shell window (command program). |
