The Jurassic Park films keep Crichton’s core premise—a dinosaur park spirals out of control—but change important character portrayals and outcomes. The first movie makes Hammond more sympathetic and leaves Ian Malcolm alive, unlike the novel. The Lost World film is a looser adaptation, shaped by those earlier screen choices. The comparison below focuses on the two Michael Crichton novels and their respective film adaptations.
How the first Jurassic Park changes the book
Michael Crichton’s Jurassic Park novel and the 1993 film share the central disaster: a dinosaur attraction becomes impossible to control. The film does not simply reproduce the book, however; it alters the emphasis and the fates of key characters.
Hammond is more sympathetic on screen
Comparison coverage describes the novel’s John Hammond as less sympathetic than the film’s version. That shift changes how the park’s creator reads: the movie gives audiences a more sympathetic figure amid the catastrophe, rather than presenting the same characterization as the book.
Malcolm survives the film
In Crichton’s novel, Ian Malcolm dies during the park disaster. The film leaves him alive. This is one of the consequential book-and-film differences because Malcolm can return as a major character in both versions of the sequel, even though the sequel’s story differs between page and screen.

Henry Wu has a larger role in the novel
Henry Wu is substantially more prominent in the novel than in the film, according to the comparison coverage. Readers who know Wu mainly from the movies will therefore find a different balance of attention in the book: his role in the park’s scientific enterprise is given more space.
How The Lost World differs from its film
The sequel comparison begins with a continuity difference. In Crichton’s The Lost World, Malcolm discovers a second island where Hammond had bred dinosaurs. The film adaptation is looser and does not simply transfer the novel’s premise and events unchanged.
Rank #2
The first film sets constraints for the sequel
The sequel film inherits the first movie’s decisions to keep Hammond and Malcolm alive. Those choices differ from the first novel, where both characters die, so the second film works from a screen continuity that the sequel novel did not establish in the same way. Its departures are therefore partly adaptation choices shaped by the preceding film, not merely omissions from the book.
Compare the sequel on three levels
- Premise: The novel’s setup centers on Malcolm discovering a second island used by Hammond to breed dinosaurs.
- Continuity: The film carries forward the screen versions of Hammond and Malcolm, who survived the first movie.
- Adaptation approach: The film is a loose adaptation, reshaping the sequel around established movie continuity rather than matching the novel beat for beat.
Which version should you read or watch?
Read the novels if you want Crichton’s original characterization, the different survival outcomes, and the second-island premise in its book form. Watch the films as adaptations with their own continuity: the first changes character emphasis and survival, while the sequel builds on those screen changes.

For a direct comparison, read Michael Crichton’s Jurassic Park and The Lost World alongside the films. Readers curious about screenplay decisions can also consult Jurassic Park: The Official Script Book, which the publisher describes as an officially licensed edition containing the final screenplay, annotations, and film stills. It offers screenwriting and production context; it is not a substitute for Crichton’s novel.
