The Lost World: Jurassic Park - DVD

Although Jurassic Park was destroyed four years ago, it didn't mean the definitive end of the dinosaurs. A second, secret island, Isla Sorna, has existed all this time. Dinosaurs were bred there "in the wild", without enclosures or supervision, before being transported to Isla Nublar.

Now, however, the crew of a cruise ship has accidentally discovered the second island, and decisive action must be taken. John Hammond (Richard Attenborough), the mastermind behind the original park, summons Ian Malcolm (Jeff Goldblum) and asks him to lead a new expedition to document the dinosaurs' lives on Isla Sorna (it seems his only qualification for this demanding job is the fact that he has already encountered dinosaurs once and survived). Coincidentally, zoological expert Sarah Harding (Julianne Moore) is already on the island. Hammond sent her ahead, and her presence, as Malcolm's former girlfriend, is meant to partly motivate him to participate. In addition, Malcolm's daughter is travelling with the expedition as a stowaway.
Soon after arriving on the island, Malcolm's team discovers they have competition: Hammond's evil nephew, Peter Ludlow (Arliss Howard), has travelled to the island with a much larger and better-equipped team (including professional hunters) to capture the dinosaurs and transport them to San Diego, where they will be displayed in a zoo. Whatever the outcome, it's clear the dinosaurs will have plenty to eat.
