A collection of essays by the author about films which were important to pop culture and the genre. The chronology includes all science fiction films from 1940 to 1949. Each essay includes a complete plot synopsis, additional analyses and notes, anecdotal information and data, where possible; since some films have been lost. Each has been selected for addition to this volume based on the author's experience as a fan of science fiction and a film critic. Some of the films may seem like cheaply made popcorn thrillers but when seen for their themes and impact they were actually quite educational.
