Biosyn is InGen's genetics rival in the novel.
Michael Crichton estimated that the screenplay has about 10 to 20% of the novel's content.
John Williams scored the film at the end of February, 1993 and recorded it a month later. He felt he needed to write "pieces that would convey a sense of awe and fascination, given it dealt with the overwhelming happiness and excitement that would emerge from seeing live dinosaurs."
Dennis Muren suggested most of the full size dinosaurs could be done on computer from head to toe, but he had to prove it first to Steven Spielberg, which he did with a skeletal Gallimimus herd running through a field. Spielberg was so blown away by the scene, especially when a fleshy T-Rex arrived on the scene; he and Tippett looked at each other and Tippett said, "I think we're extinct". Spielberg liked the line and gave it to Jeff Goldblum to say to Sam Neill in the Visitor's Centre.
The electric cars in the film are Ford Explorers, but in the novel, they were Toyotas; Steven Spielberg managed to get seven for the film. The Explorers were modified to create the illusion of automation by hiding the driver in the trunk. The jeeps were also customized for the shoot. Universal Studios, Japan has a replica of one of the Ford Explorers from the movie.
To study the movement of the Gallimimus herd, the film's digital artists were ordered to run along a stretch of road with some obstacles, their hands next to their chest.
