For more than 50 years, science fiction films have been among the most important and successful products of American cinema, and are worthy of study for that reason alone. On a deeper level, the genre has reflected important themes, concerns and developments in American society, so that a history of science fiction film also serves as a cultural history of America over the past half century. M. Keith Booker has selected fifteen of the most successful and innovative science fiction films of all time, and examined each of them at length--from cultural, technical and cinematic perspectives--to see where they came from and what they meant for the future of cinema and for America at large. From Invasion of the Body Snatchers to Star Wars, from Blade Runner to The Matrix, these landmark films have expressed our fears and dreams, our abilities and our deficiencies. In this deep-seeking investigation, we can all find something of ourselves that we recognize, as well as something that we've never recognized before.
