Blade Runner is a science fiction film released in 1982 which was loosely based on Philip K. Dick's novel, Do Androids Dream of Electric Sheep? Although originally the film was poorly received by both critics and audiences alike, Blade Runner has since become a major cult hit and an iconic film in the cyberpunk sub-genre. It was re-released on DVD in 1992, and once again in 2007 as Blade Runner: The Final Cut.
