Michael Crichton has said that his views on science and genetic engineering are largely expressed by Ian Malcolm. Steven Spielberg saw many parallels to himself in the character of John Hammond. Fittingly, he cast a fellow filmmaker in the role, who begins his tour of the park by showing a film, in which he also acts. While Malcolm is dressed entirely in black, Hammond wears all white.
While discussing chaos theory, Ian Malcolm (Jeff Goldblum) shamelessly flirts with Ellie Sattler (Laura Dern). After meeting on this film, the two actors began a romantic relationship, and were engaged for two years before breaking up.
The glass of water sitting on the dash of the Ford Explorer was made to ripple using a guitar string that was attached to the underside of the dash beneath the glass.
In the shooting script, it was written that, during the Tyrannosaur's escape, Malcolm would simply get out of the car and run away, much as Genarro had done moments before. In fact, this is how Malcolm behaves in the scene as written in the book. When the time came to film the scene, it was Jeff Goldblum's idea to make his flight more heroic, by having him distract the Tyrannosaur so Grant could save the children.
The guest's encounter with the sick Triceratops ends without any clear explanation as to why the animal is sick. Michael Crichton's original novel and the screenplay, however, includes an explanation: the Stegosaur/Triceratops lacked suitable teeth for grinding food and so, like birds, would swallow rocks and use them as gizzard stones. In the digestive tract, these rocks would grind the food to aid in digestion. After six weeks, the rocks would become too smooth to be useful, and the animal would regurgitate them. When finding and eating new rocks to use, the animal would also swallow West Indian Lilac berries. The fact that the berries and stones are regurgitated explains why Ellie never finds traces of them in the animal's excrement. |
