To film the scene when the T-Rex ate a Gallimimus, a man waved a long stick with a drawing of a T-Rex head at the end of it. Joseph Mazzello thought it looked amateurish, more like a child's drawing. It made him think of Jeff Golblum's line "Uh, now eventually you do plan to have dinosaurs on your dinosaur tour right?"
The Gallimimus vocals were done with with horses, male and female, because the females make interesting sounds when a male horse shows up like high pitched squealing. The stampede sound was running horses or cattle getting herded.
Michael Crichton was encouraged to write the novel after he took the idea about dinosaur cloning to some scientists who saw the plausibility in it. Crichton told Steven Spielberg the idea and he loved it, so Spielberg coaxed the rest of the story out of him. Spielberg then storyboarded the book (something he had never done before), with scenes he wanted to carry over to the film.
Phil Tippett created dinosaur miniatures while Stan Winston provided full size robots. Michael Lantieri supervised interactions between actors and the sets. Dennis Muren led ILM with combining these elements on film in post-production.
Work began at Stan Winston's studio in 1991 with the look of each character; Winston felt it was important in convincing the audience otherwise the film would fail, no matter how good the performances were.
Both dinosaur experts Jack Horner and Robert Bakker were consulted before making the film, and both were name-checked in the novel as well.
During the early stages, Go-Motion was considered to animate all the dinosaurs, except for the Gallimimus herd, where Dennis Muren insisted that be done with the then emergent CGI.
The T-Rex's movement-based vision was attributed in the novel to the animal's frog DNA. |
