Blade Runner

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 an adaptation of Philip K. Dick's 1968 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 on space colonies. When a fugitive group of advanced replicants led by Roy Batty (Hauer) escapes back to Earth, burnt-out cop Rick Deckard (Ford) 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 critiqued its slow pacing and lack of action. It later became a cult film, and has since come to be regarded as one of the all-time best science fiction films. Hailed for its production design depicting a high-tech but decaying future, Blade Runner is often regarded as both a leading example of neo-noir cinema as well as a foundational work of the cyberpunk genre. The film's soundtrack, composed by Vangelis, was nominated in 1982 for a BAFTA and a Golden Globe as best original score.

The film has influenced many science fiction films, video games, anime, and television series. It brought the work of Philip K. Dick to the attention of Hollywood, and several of his works later became films such as Total Recall (1990), Minority Report (2002), and A Scanner Darkly (2006). In 1993, it was selected for preservation in the U.S. National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".

Seven different versions of Blade Runner exist as a result of controversial changes requested by studio executives. A director's cut was released in 1992 after a strong response to test screenings of a workprint. This, in conjunction with the film's popularity as a video rental, made it one of the earliest movies to be released on DVD. In 2007, Warner Bros. released The Final Cut, a 25th-anniversary digitally remastered version. This is the only version over which Scott retained artistic control.

The film is the first of the franchise of the same name. A sequel, directed by Denis Villeneuve and titled Blade Runner 2049, was released in October 2017 alongside a trilogy of short films covering the thirty-year span between the two films' settings. The anime series Blade Runner: Black Lotus was released in 2021.
