What is Final temperature: Definition and 132 Discussions
Final Destination is an American horror franchise composed of five films, two comic books, and nine novels. It is based on an unproduced spec script by Jeffrey Reddick, originally written for The X-Files television series, and was distributed by New Line Cinema. All five films center around a small group of people who escape impending death when one individual (the protagonist of each film) has a sudden premonition and warns them that they will all die in a terrible mass-casualty accident. After avoiding their foretold deaths, the survivors are killed one by one in bizarre accidents caused by an unseen force creating complicated chains of cause and effect, resembling Rube Goldberg machines in their complexity, and then read omens sent by another unseen entity in order to again avert their deaths.
The series is noteworthy among other films in the horror genre in that the antagonist is not a stereotypical slasher or other physical being, but Death manifested, subtly manipulating circumstances in the environment with a design on claiming anyone who escapes their fated demise.
In addition to the films, a novel series, which includes the novelizations of the first three films, was published throughout 2005 and 2006 by Black Flame. A one-shot comic book titled Final Destination: Sacrifice was released alongside select DVDs of Final Destination 3 in 2006, and a comic book series titled Final Destination: Spring Break was published by Zenescope Entertainment in 2007.
