Kualoa Ranch was used for the Gallimimus herd scene after a hurricane ravaged Kauai.
The production originally planned to shoot the stampede sequence on Kauai, one of the Hawaiian islands used for Jurassic Park’s location work. Hurricane Iniki struck Kauai in September 1992, damaging the island and disrupting the filming schedule.
The crew moved the scene to Kualoa Ranch on Oahu about two weeks later. Its dramatic cliffs and broad landscape proved more visually striking than the flatter setting originally envisioned. In the finished sequence, the Gallimimus herd races through the valley while the Tyrannosaurus pursues and catches one animal.
The storm affected more than the location. Spielberg and a small crew captured footage during the hurricane that was incorporated into the movie’s storm scenes. Another planned sequence—in which Velociraptors killed Ray Arnold onscreen—was abandoned, leaving Arnold’s death to occur offscreen.
