Jurassic Park, later also referred to as Jurassic World, is an American science fiction media franchise created by Michael Crichton and centered on a disastrous attempt to create a theme park of cloned dinosaurs. It began in 1990 when Universal Pictures and Amblin Entertainment bought the rights to Crichton's novel Jurassic Park before it was published. The book was successful, as was Steven Spielberg's 1993 film adaptation. The film received a theatrical 3D re-release in 2013, and was selected in 2018 for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". A 1995 sequel novel, The Lost World, was followed by a film adaptation in 1997. Subsequent films in the series from Jurassic Park III (2001) onward are not based on novels by Crichton.

John Michael Crichton was an American author, screenwriter and filmmaker. His books have sold over 200 million copies worldwide, and over a dozen have been adapted into films. His literary works heavily feature technology and are usually within the science fiction, techno-thriller, and medical fiction genres. Crichton’s novels often explore human technological advancement and attempted dominance over nature, both with frequently catastrophic results; many of his works are cautionary tales, especially regarding themes of biotechnology. Several of his stories center specifically around themes of genetic modification, hybridization, paleontology and/or zoology. Many feature medical or scientific underpinnings, reflective of his own medical training and scientific background.
