In The Lost World: Jurassic Park, the escaped Tyrannosaurus rex reaches San Diego.
The animal is transported from Isla Sorna to California aboard a cargo ship, but the vessel reaches port after the crew has been killed. The Tyrannosaurus escapes and wanders through San Diego, creating the film’s major city-set action sequence.
The sequence was notable because it moved the franchise’s dinosaur danger beyond an isolated island. The animal visits locations including a residential neighborhood and the city’s urban streets before being recaptured and returned to Isla Sorna.
The film explains that InGen intended to exploit the dinosaur as an attraction in San Diego. This plot differs from the first film, where the park’s catastrophe remains confined to Isla Nublar. The city sequence is also why the film is sometimes remembered as the franchise’s “dinosaur in the city” story.
