Michael Crichton's techno-thriller became one of the biggest blockbusters of all time. But the novel and the film diverge more than most fans remember, right down to who survives.
The Book
Jurassic Park
by Michael Crichton
The Film
Jurassic Park
Directed by Steven Spielberg, 1993
🔀 What Changed
Spoiler warning: this section discusses plot changes, including the ending.
The novel's John Hammond is a ruthless, profit-driven figure who dies being swarmed by Procompsognathus dinosaurs, a fate the film cuts entirely, softening him into a well-meaning grandfather who survives. Crichton's book also gives velociraptors and the T. rex far more graphic, sustained violence toward humans, including additional character deaths not shown onscreen. The novel spends considerably more time on chaos theory and Ian Malcolm's philosophical monologues, most of which were trimmed for pacing. Ellie Sattler's role was also expanded on screen, giving her more agency in the park's climax than she has in the source novel.
🎙️ What the Author Said
Crichton was closely involved in the adaptation, co-writing an early draft of the screenplay himself and working directly with Spielberg during development. He publicly expressed enthusiasm for the film, and reporting from the production described the collaboration as unusually smooth for a Hollywood adaptation, with Crichton supportive of the changes made to fit the format, including Hammond's softened characterization.
“Crichton co-wrote an early screenplay draft himself.”
The book digs deeper into chaos theory and consequence; the film built a cultural phenomenon. Which version earns your vote?
