Blade Runner is a 1982 American Sci-fi fiction film based on the novel Do Androids Dream of Electric Sheep? By Philip K. Dick. The film takes place in LA in November 2019, where genetically engineered organic robots who visually look the same as humans, are manufactured by Tyrell Corporation. They are banned from Earth, but those that return to Earth are hunted and killed or “retired” by special police operatives “Blade Runners.”
The theme of identity is very apparent in this film, not only with the replicants but also with Harrison Ford’s non-replicant character, Deckard. While each replicant tries to make his or her’s own identity with the memories they are told by Tyrell or, whether they choose to be good or bad. However the replicants do not have long to find those identities, as they will either be hunted or die after 4 years. The same sense of identity is seen with Deckard. He has been brought onto this mission to kill any replicants on Earth, however he finds himself having feelings and helping one of these replciants named Rachael. Deckard does not see her as a replicant because she has such vivid memories and even pictures – those memories and pictures however are of Tyrell’s neice.
The replicants have 4 years to find their identity; some were evil such as Roy and Pris, some were almost human-like, Rachael and others went about trying to live a “normal” life. Deckard thinking his identity as a Blade Runner are over until he is called back onto the job near the start of the movie, he then finds himself totally emerged into his work, retiring replicants everywhere. Until Rachael, he finds a companion in her and develops feelings for her, choosing to protect her and run off with her at the end.
