"Blade Runner is a 1982 American science fiction film, directed by Ridley Scott and starring Harrison Ford, Rutger Hauer, and Sean Young. The screenplay, written by Hampton Fancher and David Peoples, is based on the novel Do Androids Dream of Electric Sheep? by Philip K. Dick".
"The film depicts a dystopian Los Angeles in November 2019 in which genetically engineered organic robots called replicants—visually indistinguishable from adult humans—are manufactured by the all-powerful Tyrell Corporation as well as other mega manufacturers around the world. Their use on Earth is banned, and replicants are exclusively used for dangerous, menial or leisure work on Earth's off-world colonies. Replicants who defy the ban and return to Earth are hunted down and "retired" by police special operatives known as "blade runners".
