<P> 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". A sequel, Blade Runner 2049, was released in October 2017 . </P> <P> Seven versions of Blade Runner exist as a result of controversial changes made at the request of 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 first movies to be released on DVD . In 2007, Warner Bros. released The Final Cut, a 25th - anniversary digitally remastered version, and the only version over which Scott retained artistic control . The Final Cut was shown in selected theaters and released on DVD, HD DVD, and Blu - ray . </P> <P> In 2019 Los Angeles, former police officer Rick Deckard is detained by officer Gaff and brought to his former supervisor, Bryant . Deckard, whose job as a "blade runner" was to track down bioengineered beings known as replicants and "retire" (kill) them, is informed that four are on Earth illegally . Deckard starts to leave, but Bryant ambiguously threatens him and he stays . The two watch a video of a blade runner named Holden administering the "Voigt - Kampff" test, which is designed to distinguish replicants from humans based on their emotional response to questions . The test subject, Leon, shoots Holden on the second question . Bryant wants Deckard to retire Leon and the other three Tyrell Corporation Nexus - 6 replicants: Roy Batty, Zhora, and Pris . </P> <P> Bryant has Deckard meet with Eldon Tyrell so he can administer the test on a Nexus - 6 to see if it works . Tyrell expresses his interest in seeing the test fail first, and asks him to administer it on his assistant Rachael . After a much longer than normal test, Deckard concludes Rachael is a replicant who believes she is human . Tyrell explains she is an experiment who has been given false memories to provide an emotional "cushion". </P>
