Blade Runner (R) is a 1982 American neo-noir science fiction film directed by Ridley Scott, written by Hampton Fancher and David Peoples, and starring Harrison Ford, Rutger Hauer, Sean Young, and Edward James Olmos. It is a loose adaptation of the 1968 novel Do Androids Dream of Electric Sheep? by Philip K. Dick. The film is set in a dystopian Los Angeles in 2019, and depicts a future in which synthetic humans known as replicants are bioengineered by the powerful Tyrell Corporation to work on off-world colonies. When a fugitive group of replicants led by Roy Batty (Hauer) escape back to Earth, burnt-out cop Rick Deckard (Ford) reluctantly agrees to hunt them down. During his investigations, Deckard meets Rachael (Young), an advanced replicant who causes him to question his work. The film has been highly influential on many science fiction films, video games, anime, and television series. The film brought the work of Philip K. Dick to the attention of Hollywood, and several later films were based on his work. Scott regards Blade Runner as "probably" his most complete and personal film. In the year after its release, the film won the Hugo Award for Best Dramatic Presentation, and in 1993 it was selected for preservation in the United States National Film Registry by the Library of Congress as "culturally, historically, or aesthetically significant". In 2007, Warner Bros. released The Final Cut, a 25th-anniversary digitally remastered version, and the only version over which Scott retained artistic control.
