He is also the main protagonist of the film adaptation, titled "The Lost World: Jurassic Park". In the four years since the incident on Isla Nublar, Malcolm loses his reputation, credibility, and university tenure due to his assertions of living dinosaurs, which InGen denies along with the entire Jurassic Park incident. Despite his animosity towards the company, Malcolm is among those hired by John Hammond to visit the island and document the dinosaurs in their natural habitat. Malcolm goes in order to rescue his girlfriend Dr. Sarah Harding who had already set out for the island. Malcolm's earlier experience with the "Tyrannosaurus" at Isla Nublar aids his survival, and he and Sarah work to stop a "Tyrannosaurus" which a rival expedition led by Peter Ludlow had brought to San Diego. This restores Malcolm's reputation, and the Jurassic Park survivors become renowned.
