In the film "Jurassic Park," billionaire John Hammond, played by Richard Attenborough, brings paleontologists Alan Grant, played by Sam Neill, and Ellie Sattler, played by Laura Dern, as well as mathematician Ian Malcolm, played by Jeff Goldblum, to help him bring dinosaurs back to life for his dinosaur theme park. Hammond's fascination and desire to revive dinosaurs backfires when many of them break free and start to terrorize the park-goers.
