Blade Runner is a 1982 American neo-noir science fiction film, directed by Ridley Scott. The screenplay, written by Hampton Fancher and David Peoples, was based on the novel Do Androids Dream of Electric Sheep? by Philip K. Dick. The film stars Harrison Ford and features Rutger Hauer, Sean Young, Edward James Olmos, Daryl Hannah, M. Emmet Walsh, William Sanderson, Joe Turkel, Brion James and Joanna Cassidy.The film depicts a dystopian Los Angeles in November 2019 in which genetically manufactured beings called replicants—visually indistinguishable from adult humans—are used for dangerous and degrading work in Earth's "off-world colonies". Following a small replicant uprising, replicants become illegal on Earth; and specialist police units called "blade runners" are trained to hunt down and "retire" (kill) escaped replicants on Earth. The plot focuses on a brutal and cunning group of replicants hiding in Los Angeles and a semi-retired blade runner, Rick Deckard (Ford), who reluctantly agrees to take on one more assignment.
