The Lost World: Jurassic Park (commonly referred to as The Lost World) is a 1997 American science fiction film and the second Jurassic Park film as part of the Jurassic Park franchise. The film succeeds Jurassic Park directed by Steven Spielberg, based on the novel of the same name by Michael Crichton. The film centers on the island of Isla Sorna, an auxiliary site for the main Jurassic Park island, where dinosaurs have taken over and live in the wild. Ian Malcolm leads a team to document the dinosaurs in their native habitat, while an InGen team attempts to capture them for a second Jurassic Park in San Diego.

After the release of the original Jurassic Park book and the success of the first film, Crichton was pressured not only by fans, but Spielberg himself, for a sequel novel. After the book was published in 1995, production began on a film sequel.

After a small girl is attacked by a small group of compsognathus, Ian Malcolm (Goldblum) discovers that there is a second island full of a variety of dinosaurs. Dr. John Hammond (Attenborough) decides to send four adventure to monitor the dinosaur's lifestyle before INGEN move forward in controlling the island. Ian Malcolm doesn't like the idea and wants to contact the other three members, but before he can contact them, he finds out that his girlfriend, Sarah Harding (Moore) is already on the island. Now, what was supposed to be a natural viewing of the incredible creatures in their habitats, has turned into a rescue mission with everyones life at danger. Written by Film_Fan

Four years after the failure of Jurassic Park on Isla Nublar, John Hammond reveals to Ian Malcolm that there was another island ("Site B") on which dinosaurs were bred before being transported to Isla Nublar. Left alone since the disaster, the dinosaurs have flourished, and Hammond is anxious that the world see them in their "natural" environment before they are exploited. Written by Murray Chapman

Ian Malcolm is recruited by John Hammond to lead a research team to Isla Sorna, an island 87 miles to the south of Isla Nublar (the site of the original Jurassic Park). Here, InGen Bioengineering had constructed the secret "Site B", where the dinosaurs were actually bred and then transported to the park. Hammond's nephew, who has taken control of InGen, leads his own team to the island to capture the dinos and bring them back to the U.S. to become attractions at a "dino park" in San Diego. The dinos cause havoc and have a field day with the movable "feast." Written by John Deming

With the apparent public discovery of the 'Site B' production island full of dinosaurs, John Hammond assembles a team to visit and document the area before it is exploited by others. Included in the four man team are Dr. Ian Malcolm and his girlfriend, Dr. Sarah Harding. When the team reaches the island, they soon discover the presence of another group of people. This new group however are not there for biological data but instead have something more sinister in mind. After a series of events, both groups become stranded when all their communication equipment is lost. It is then that the terror really begins as both groups scramble for their lives. Written by P.

The film picks up four years after the disaster at Jurassic Park. On a nearby island, dinosaurs have secretly survived and been allowed to roam free but now there is a more ominous threat--a plan to capture and bring the dinosaurs to the mainland. John Hammond, who has lost control of his InGen company, sees a chance to redeem himself for his past mistakes and sends an expedition led by Ian Malcolm to reach the island before the mercenary team gets there. The two groups confront each other in the face of extreme danger and must team up for their own survival in a race against time. Written by Robert Lynch
