The Lost Word: Jurassic Park is director Steven Spielberg’s sequel to his original dinosaur thriller. Dr. Ian Malcolm (Jeff Goldblum) returns for more dino-horror when, four years after the disaster at the would-be amusement park, another expedition is mounted by millionaire John Hammond (Richard Attenborough). To document the natural behavior of the beasts at a mysterious Site B, Hammond sends a team comprising Malcolm; Malcolm's girlfriend, paleontologist Dr. Sarah Harding (Julianne Moore); and a wildlife videographer (Vince Vaughn). They face adversity in the form of a less-than-scrupulous big-game hunter (Pete Postlethwaite) and, of course, the terrible lizards themselves. The film is loosely based on Michael Crichton's novel The Lost World, which was named after the 1912 Sir Arthur Conan Doyle novel of the same name. Spielberg proved his determination to alternate making socially conscious films with directing movies of sheer entertainment value; his prior film to The Lost Word was Schindler's List, and he followed the dinosaur adventure with Amistad.
