Probably Ray Bradbury’s best-known work, and the source of most fanfiction set in his writings, Fahrenheit 451 takes place in the not-too-distant future where books are burned by firemen to prevent them from making people think, as ignorance is bliss. One fireman, Guy Montag, begins to question this behavior and his role in it, eventually rebelling and trying to rescue books. The novel is a combination and running together of several older stories by Bradbury about a (much older) fireman in a similar situation.
Fahrenheit 451 was made into a film released in 1966. Details were changed from the novel (the name of Montag’s wife changed from Mildred to Linda, the action was moved from America to Great Britain, Montag is suddenly and inexplicably German), the themes and messages behind the novel are largely intact. The biggest deviation is the absence of the Mechanical Hound, a spider-like hunting robot, which was replaced by the more special effects budget–friendly "men in jet packs with clearly visible wires."
