Deckard confirmed formaybereplicant
>Because the first movie is the story of a human falling in love with a designed human being and the story of the [other edit] is the story of a replicant who didn’t know he’s a replicant and slowly discovers his own identity. Those are two different stories. I felt like the key to deal with that was in the original novel. IN the novel, the characters are doubting about themselves; they are not sure if they are replicants or not. For time to time, they’re doing Voigt-Kampff on themselves to make sure that they’re humans. I love that idea. So I decided that the movie would be on that side, too, that Deckard in the movie is as unsure as we are about what his identity is. That, I love it, because I love mystery. That’s an interesting thing to me—not the knowing who he is or not—but the doubt [of it].”
