This is a quick rant for other Blade Runner nerds. Below explains more.
The whole film director Ridley Scott is showing us that Replicants have human emotions and that they love and hate and that they are very human but emotionally they are like children in a way because they only live until 4 years old. So by the end of the film when we hear Roy Batty’s tears in the rain speech we know that whether one’s soul is mechanical or human that they are the same. So what would it matter if Deckard was a Replicant? It actually just makes Deckard’s life a parallel to Roy Batty’s. At the end of the film whether Deckard discovers his own human soul or his mechanical soul it is just as profound because by the end the whole message of the film is that are the similar to humans and they are not villains, they are just like people.
Last night I drank wine and watched Blade Runner for the 100 time. So may people make a big deal out of whether Deckard is a Replicant or a human. If you hear Ridley Scott talk about why Deckard IS a replicant it’s really hard to argue against. Deckard has a memory implant of a unicorn which only he could know, Gaff leaves an origami Unicorn on Deckard’s doorstep meaning that Gaff somehow has knowledge or Deckards personal memories just like when Deckard described Rachael’s childhood memories that only she could know. When Deckard picks up the paper unicorn we hear from Gaff “It’s too bad she won’t live but then again who does”. “But then again who does” I take to me Deckard your not going to live long either because you too are a replicant but obviously even without reading into Gaff’s line it still seem clear Deckard is a Replicant at least to me. He also has the red replicant glow in his eyes in one scene. If you think about it, the film is told from a perspective a being that does not know he is a Replicant.
I heard Frank Darabont (a hero of mine) talking about Blade Runner . His perspective is that Blade Runner is about a sort of souless human hunting down these Replicants who act more alive and more human then he himself does. Even after killing several Replicants, Roy Batty the Replicant leader saves Deckard’s life and just before he dies for lack of better words bears his soul to Deckard when we hear Batty’s Tears in the rain speech.
“I’ve seen things you people wouldn’t believe.
Attack ships on fire off the shoulder of Orion.
I watched C-beams glitter in the dark near the Tannhauser gate.
All those moments will be lost in time, like tears in rain.
Time to die.”
Roy Batty then dies and you sense that Deckard has seen the soul of Roy Batty and in seeing this regains his own humanity. So Deckard finds his own humanity, gives up killing, sees that Rachael is a being worth saving and presumably leaves town. So Franks perspective is that if Deckard is a Replicant, then he can not discover his own humanity and that the plot unravels but I disagree. I say it doesn’t matter.
