Which Jurassic Park film was the first to show dinosaurs attacking San Diego?

The Lost World: Jurassic Park was the first Jurassic Park film to show dinosaurs attacking San Diego.

Released in 1997, the film ends with a Tyrannosaurus rex escaping into the city after being transported from Isla Sorna. The sequence includes the animal moving through streets, damaging vehicles, and confronting people before it is returned to the island.

This was a major expansion of the franchise’s setting. The original Jurassic Park is almost entirely confined to Isla Nublar, while The Lost World explores the consequences of bringing a dinosaur into a populated mainland environment.

Jurassic Park III returns to an island setting, and the later Jurassic World films broaden the story further. The San Diego sequence remains distinctive because it is the franchise’s first large-scale dinosaur attack in a modern city.
