Blade Runner is a 1982 science fiction film directed by Ridley Scott, and written by Hampton Fancher and David Peoples. Starring Harrison Ford, Rutger Hauer, Sean Young and Edward James Olmos, it is loosely based on Philip K. Dick's novel Do Androids Dream of Electric Sheep?. The film is set in a dystopian future Los Angeles of 2019, in which synthetic humans known as replicants are bio-engineered by the powerful Tyrell Corporation to work at space colonies. When a fugitive group of advanced replicants led by Roy Batty escapes back to Earth, burnt-out cop Rick Deckard reluctantly agrees to hunt them down. Blade Runner initially underperformed in North American theaters and polarized critics; some praised its thematic complexity and visuals, while others were displeased with its slow pacing and lack of action.
