Science fiction, fantasy and horror films have spawned more sequels than any other film genre. While the perhaps overly familiar Dracula and Frankenstein have inspired dozens of additional films, such movies as Quatermass and Francis have also produced several sequels. Over 400 horror, science fiction and fantasy films are analyzed in this comprehensive reference to the genre's sequels, series and remakes. Filmographies are given for each film, providing year of release, studio, running time, cast and credits. This is followed by a plot synopsis, reviews of the work, and a critical analysis.
