John Michael Crichton (1942 –2008) was an American author, producer, director and screenwriter (sceneggiatore) , best known for his work in the science fiction, medical fiction, and thriller genres based on action and technology. Among others, he wrote Jurassic Park (1990), Congo (1980), Sphere (1987), State of Fear (2004), Next (2006) and Pirate Latitudes, published posthumously in 2009. An unfinished techno-thriller; Micro, completed by Richard Preston, has been released (pubblicato) in the fall (fine) of 2010. Crichton was also the creator and executive producer of the television drama ER. The majority of his books have been adapted into films. Among the most famous is Jurassic Park (1990), a science fiction novel about imprudent biological searches (ricerche). The story deals with (tratta) a billionaire who creates a technique to clone (per clonare) dinosaurs and locks (rinchiude) the animals in a sort of theme park island behind electrified fences (siepi dove scorre energia elettrica). He thinks many people come and visit his amazing (straordinarie) creatures and asks a group of scientists to come and view the park. Unfortunately something terribly goes wrong (va male). The novel was adapted into a film in 1993 by director Steven Spielberg. The book’s sequel, The Lost World (1995), was also adapted by Spielberg into a film in 1997. The title of the sequel is probably an homage to Sir Arthur Conan Doyle, Sherlock Holmes’ father, who wrote a series of novels about the adventures of the eccentric and unsociable scientist Professor Challenger; the first was The Lost World in 1912, about a journey in a prehistoric land.
