And illuminati actresses and actors galore..............

In 1975, Crichton ventured into the nineteenth century with his historical novel The Great Train Robbery, which would become a bestseller. The novel is a recreation of the Great Gold Robbery of 1855, a massive gold heist, which takes place on a train traveling through Victorian era England. A considerable portion of the book was set in London. The novel was later made into a 1979 film directed by Crichton himself, starring Sean Connery and Donald Sutherland. The film would go on to be nominated for Best Cinematography Award by the British Society of Cinematographers, also garnering an Edgar Allan Poe Award for Best Motion Picture by the Mystery Writers Association of America.

In 1976, Crichton published Eaters of the Dead, a novel about a tenth-century Muslim who travels with a group of Vikings to their settlement. Eaters of the Dead is narrated as a scientific commentary on an old manuscript and was inspired by two sources. The first three chapters retell Ahmad ibn Fadlan's personal account of his journey north and his experiences in encountering the Rus', the early Russian peoples, whilst the remainder is based upon the story of Beowulf, culminating in battles with the 'mist-monsters', or 'wendol', a relict group of Neanderthals. The novel was adapted into film as The 13th Warrior, initially directed by John McTiernan, who was later fired with Crichton himself taking over direction.

In 1980, Crichton published the novel Congo, which centers on an expedition searching for diamonds in the tropical rain forest of Congo. The novel was loosely adapted into a 1995 film, starring Laura Linney, Tim Curry, and Ernie Hudson.

Seven years later, Crichton published Sphere, a novel which relates the story of psychologist Norman Johnson, who is required by the U.S. Navy to join a team of scientists assembled by the U.S. Government to examine an enormous alien spacecraft discovered on the bed of the Pacific Ocean, and believed to have been there for over 300 years. The novel begins as a science fiction story, but rapidly changes into a psychological thriller, ultimately exploring the nature of the human imagination. The novel was adapted into the film Sphere in 1998, directed by Barry Levinson, with a cast including Dustin Hoffman as Norman Johnson, (renamed Norman Goodman), Samuel L. Jackson, Liev Schreiber and Sharon Stone.
