This examination and comprehensive assessment of apocalyptic film studies fifty films that illustrate the variety, range and different categories of the genre. Apocalyptic films are those that depict, on screen as part of the story, an event threatening the extinction of mankind. A brief overview identifies seven major categories of apocalyptic films: the religious or supernatural, celestial collision, solar or orbital disruption, nuclear war and radioactive fallout, germ warfare or pestilence, alien device or invasion, and scientific miscalculation. Alphabetically arranged entries rate the films and provide production information, an annotated cast listing, a synopsis of the film, a critique, and representative quotes. Film scholars and those with a special interest in apocalyptic cinema will appreciate the overview and detailed analysis of the films. Appendices provide additional examples of apocalyptic movies excluded from the main text, a sampling of post-apocalyptic cinema which is distinct from the apocalyptic genre and examples of apocalyptic television. Illustrations are included.
