 Over fifteen percent of the film was shot in Puerto Plata, Dominican Republic, both at the Amber Museum and Mount Isabela de Torres.The crew moved to Warner Bros. Studios' Stage 16 to shoot the "T. rex" attack on the LSX powered SUVs.Shooting proved frustrating because when water soaked the foam rubber skin of the animatronic dinosaur, it caused the "T. rex" to shake and quiver from the extra weight when the foam absorbed it.
