Famous Monsters of Filmland is an American genre-specific film magazine, started in 1958 by publisher James Warren and editor Forrest J Ackerman.
Famous Monsters of Filmland directly inspired the creation of many other similar publications, including Castle of Frankenstein, Cinefantastique, Fangoria, The Monster Times, and Video Watchdog. In addition, hundreds, if not thousands, of FM-influenced horror, fantasy and science fiction movie-related fanzines have been produced, some of which have continued to publish for decades, such as Midnight Marquee and Little Shoppe of Horrors.
Famous Monsters of Filmland was originally conceived as a one-shot publication by Warren and Ackerman, published in the wake of the widespread success of the Shock Theater package of old horror movies syndicated to American television in 1957. But the first issue, published in February 1958, was so successful that it required a second printing to fulfill public demand. Its future as part of American culture was immediately obvious to both men. The success prompted spinoff magazines such as Spacemen, Favorite Westerns of Filmland, Screen Thrills Illustrated, Creepy, Eerie, and Vampirella.
FM offered brief articles, well-illustrated with publicity stills and graphic artwork, on horror movies from the silent era to the current date of publication, their stars and filmmakers. Warren and Ackerman decided to aim the text at late pre-adolescents and young teenagers.
