The reason Velociraptors and Deionychus share the same attributes in the film is allegedly because Michael Crichton got them mixed up in the novel.
During the kitchen scene, the Raptors are outmaneuvered more than once, perhaps because they're outside they're element, and are unfamiliar with a man-made environment, e.g. the reflective surfaces they mistake for Lex. Its often the film's most celebrated scene, at least whenever the T-Rex is not around.
Michael Crichton spent years working on the story, trying to convince himself the premise was not so unlikely; he had to do a lot of research before he could.
Steven Spielberg managed to acquire the film rights before the novel was even published for $1.5 million in 1990
Michael Crichton was hired to adapt his novel for the big screen for $500,000, but David Koepp wrote the final draft, leaving out much of the novel's exposition and violence, as well as making a few character changes.
The film used CGI to bring dinosaurs to life. When Michael Crichton directed Looker (1981), he predicted such a technology, but put to far more sinister purposes. Crichton was always a skeptic about new technologies.
Jurassic Park gave a much needed boost to Michael Crichton's flagging career. After the global success of the film, Crichton became a hot commodity in Hollywood, with many of his novels adapted into films.
The Raptors seem far more interested in hunting the humans on the island. The only time they ever attack another dinosaur is when the T-Rex attacks them at the climax.
Steven Spielberg knew as soon as his kids saw the model T-Rex they wouldn't want to go home, which is just the reaction he wanted. Michael Crichton also viewed the model and was impressed. |
