Corrected entry: When Roy kisses the dead Pris, her tongue is sticking out. When his mouth moves away from hers, her tongue has disappeared.
Corrected entry: File footage descriptions provided to police on escaped replicates Zora (snake lady) and Pris are reversed. Zora was an inefficient killer and Pris was. Also, a basic pleasure model (Zora, not Pris) would take a job as a sexual entertainer.
Correction: There is no mistake there. Zhora was smart enough to try and strangle Deckard with his tie, so as not to leave any physical evidence before dumping the body. Anyone could have strangled him, no one would suspect an exotic dancer/replicant. And Pris "A Basic Pleasure Model" was quite obvioulsy dressed as a prostitue and her idea of attacking Deckard is to do a cartwheel and gymnastic display.
Yep. To add, the only reason Zhora doesn't succeed in killing Deckard is because other people walk into the room. She is much more efficient in her attack than Pris. She's also very serious and cynical while Pris plays innocent and flirty. Zhora is also more of a Vegas showgirl or burlesque dancer which is quite a different job and skill set from being a prostitute, which to me is what "pleasure model" implies.
Corrected entry: As Deckard (Harrison Ford) stalks Batty (Rutger Hauer) in the building at the end, you see him walk through a room and briefly the shadow of two crew members (one is the director Ridley Scott) skims across the wall.
Correction: Sebastian's toys had the run of the place. Why couldn't it have been one of them?
It looks like one of them is holding a camera.
Corrected entry: When Batty is in the phone booth shaking his hand, the nail stuck in his hand at the end of the movie is seen as he turns his hand. Also, someone's hand is visible on his right sholder.
Correction: This is not a mistake, but rather an artistic choice. Both of these short images repeat later in the film (Tyrell's apt and the final fight.) Scott was trying to portray some sort of android premonition or something.
They went so far as to alter these shots in the Final Cut to remove the thumb on Roy's shoulder and have the backgrounds better blend in with the phone booth. It really doesn't seem like these shots were ever meant to be a flash forward at all.
Correction: Exactly, he has just kissed her pushing her tongue back in her mouth.
He did not kiss her on the mouth, or any way that would have 'pushed' her tongue back in. He kissed her on the cheek, near the mouth.
