Holden need to
Leon, if the police knew what he looked like? This
test is more crucial in the novel, where it is intimated that there are
humans who have actually been replaced by look-alike replicants. Replicants,
however, can readily change their appearances and aren't easily recognized
from photographs, e.g., Zhora's tattoo, and Pris' raccoon makeup. In the
July 1980 screenplay, Deckard muses, "They could change their appearances but
not their future." In the December 1980 screenplay, Deckard says Zhora's
"black hair is a wig which now hangs on the wall next to the shower. She
didn't look like Nexus designated Zhora to begin with, but even less now."
Bryant tells Deckard that there were six replicants, three male, three
female. Obviously, Roy and Leon are two of the males, and Pris and Zhora are
two of the females. Bryant also says that "one of them got fried trying to
get into the Tyrell building", but doesn't specify the sex. That leaves one
replicant, either male or female. It has been hypothesized that
Deckard was the sixth replicant, but there is ample evidence that this is not the case.
In an earlier version of the script
was the fifth replicant, and
was the sixth. Bryant's line in that script got past the screenwriter
unnoticed. It was recorded correctly in the Workprint as "two got fried" but
botched again on the release print.
Why is it so difficult to tell a replicant from a human, when replicants can
put their hands in boiling/freezing liquids without damage? Surely a tissue
sample would suffice? Perhaps, but Holden couldn't even get a straight
answer from Leon, much less a tissue sample.
How did word of Rachael's escape get out so quickly, and how could Tyrell
tell that she had gone for good? Remember that Deckard called Rachael at
home while he was still at the nightclub. It could not have been more than a
couple hours before he gave chase to Zhora. (How long could she "take the
pleasures from the serpent"?) Was that enough time for Rachael to run away
then for Tyrell to call the police and have Bryant put Deckard onto her?
Another explanation is that Tyrell's "experiment" was voided when Rachael
discovered she was a replicant; Tyrell simply used this opportunity to
dispose of her.
How did Roy get into Tyrell's office so easily? Did Tyrell trust Sebastian
enough to give him the option of bringing anyone/anything up in the lift?
Tyrell was unaware there was anyone in the lift with Sebastian until he said
"I brought a friend." In earlier scripts, Sebastian and Chew both held the
highest security clearance.
In an early version of the script, Tyrell was a replicant, and Roy picks up
on this because of a key both Sebastian and Tyrell are wearing. In that
version, the real Tyrell was in a "cryocrypt", sketches of which appear in
The Blade Runner
Sketchbook. After Roy kills the replicant Tyrell, he makes Sebastian show
him the crypt where the real Tyrell lies dead because of a
mistake Sebastian had made.
