At this point I invented a kind of contemplative voice-over for Deckard. Here, let me read it to you [Peoples now quotes from his December 15, 1980 script]
"'I wonder who designs the ones like me... and what choices we really have. I wondered if I had really loved her. I wondered which of my memories were real and which belonged to someone else. The great Tyrell hadn't designed me, but whoever had hadn't done so much better. "You're programmed, too," she told me, and she was right. In my own modest way I was a combat model. Roy Batty was my later brother.'
"Now, what I'd intended with this voice-over was mostly metaphysical," People's continues. "Deckard was supposed to be philisophically questioning himself about what it was that made him so different from Rachael and the other replicants. He was supposed to be realizing that, on the human level, they weren't so different. That Deckard wanted the same things the replicants did. The 'maker' he was refering to wasn't literally Tyrell, either. It was supposed to be God. So basically, Deckard was just musing about what it meant to be human.
"But then Ridley--" People says, laughing "--well, I think Ridley misinterpreted me. Because right about this period of time he started announcing, 'Ah-ha! Deckard's a replicant! What brilliance! How Heavy Metal!
' I was sort of confused by this response, because Ridley kept giving me all this praise and credit for this terrific idea. It wasn't until many years later, when I happened to be browsing through this draft, that I suddenly realized the metaphysical material I had written could just as easily have been read to imply that Deckard was a replicant. Even though it wasn't what I meant at all. What I had
meant was, we all have a maker, and we all have an incept date. We just can't address them. That's one of the similarities we had to the replicants. We couldn't go find Tyrell, but tyrell was up there somewhere. for all of us.
