Perhaps one of the greatest horror movies to date, The Shining was directed by Stanley Kubrick and adapted from Stephen King’s novel of the same name. King has famously criticized Kubrick’s take on the story, which was co-written for the screen by Kubrick and Diane Johnson, due to the significant changes in theme and downplaying of supernatural forces in the film.

The classic 1997 slasher I Know What You Did Last Summer was loosely based on Lois Duncan’s 1973 novel of the same name. The novel and the film are quite dissimilar, as the novel is closer to suspense while the film leans heavily into the slasher genre with supernatural elements.

The adaptation of the novel was written by Kevin Williamson, who is best known for his work writing Scream (1996). I Know What You Did Last Summer also launched a franchise like Scream, along with a 2021 remake in the form of a series.

The interviews recount the various social, environmental, and political changes that occurred as a result of the outbreak.

The 2013 film was directed by Marc Forster and written by Matthew Michael Carhanan, Drew Goddard, and Damon Lindelof. Unlike the novel, World War Z follows one man (Pitt) and his family at the beginning of a zombie outbreak as he searches for safety and a cure.

Another adaptation of a Stephen King novel, Gerald’s Game (2017) was directed and co-written by Mike Flanagan.

Robert Bloch’s 1959 novel, Psycho, is the source material for Alfred Hitchcock’s famous 1960 horror film. Written mainly by Joseph Stephano, Psycho is fairly faithful to the source material. Some aspects were changed for the silver screen. Namely, the film’s violence was toned down.

Silence Of The Lambs (1991) became a worldwide success and nearly swept the Academy Awards, and it is based on the 1988 horror novel written by Thomas Harris. Both the novel and film tell the story of the famous Dr. Hannibal Lecter as he’s profiled by a young FBI agent, Clarice Starling, while she searches for a new serial killer actively hunting local women.

Silence Of The Lambs is the sequel to Harris’s novel, Red Dragon. The Red Dragon film wasn’t released until 2002 and received less acclaim.

The acclaimed 2020 film The Invisible Man is inspired by H.G. Wells’ novel of the same name, which was published in 1897. The Invisible Man follows Cecelia Kass as she escapes an abusive relationship with Adrian, who then takes his own life. Cecelia believes that Adrian has faked his death and is following her. Strange happenings begin occurring around Cecelia which seem to confirm that Adrian isn’t dead, and events spiral as the story continues.

The novel and the film are very different due to the differences in when the stories were written. However, Leigh Whannell, writer and director of the film, turns a famous story into a terrifying film with many meanings behind it.

The Ring (2002) is an adaptation of the Japanese horror/mystery novel, Ring, by Koji Suzuki. The Ring was directed by Gore Verbinski and written by Ehren Kruger. As the film is an Americanization of the novel and the previous 1998 Japanese film adaptation, significant creative liberties were taken.

The film was successful upon its release and has garnered cult status. The Ring's success also opened doors for American remakes of other Japanese horror films, like The Grudge.
