Continuity mistake: Deckard shoots Zhora twice. Both times she is shot, you can see the wound explode out of her right shoulder. But moments later when she is on the ground dead, she is face down and you can see a bullet wound on both right and left shoulders. (00:58:50)
Revealing mistake: Near the beginning of the film when Deckard and the other cop take off in the car to go to the police station, you can see the cables lifting the car up into the air. (00:10:05)
Continuity mistake: When Zhora attacks Deckard, she isn't wearing any lipstick. After she is killed and they roll her over, she has bright red lipstick on. (00:59:10)
Continuity mistake: When Deckard shoots the snake-woman in the back and she falls through several layers of glass she lands on her stomach, with her head lying on the left side. In the next scene Deckard is standing beside her, but now she has turned her head, lying on the other cheek. Her arms also change position. (00:58:30)
Continuity mistake: When Roy throws Deckard to the ground after having rescued him, Deckard's shirt has ridden halfway up his torso, but when the shot cuts to behind Roy, the shirt is down. (01:45:45)
Revealing mistake: When Leon and Deckard are fighting in the street, Leon swings at Deckard and puts a hole through a steel vessel where steam blasts out. It's clear that the spot where Leon hits has been cut out and is visible before he hits it. (01:02:15)
Continuity mistake: When Deckard makes a hardcopy of the picture on the screen, it doesn't match the screen picture. The screen shot is a profile of Zhora; the hardcopy is a frontal view. (00:46:00)
Other mistake: Just before Leon's questioning starts, Holden turns on the VK and the eye monitor censor piece flips out. There is a view from Holden's perspective showing Leon's eye in on the screen, meaning the eye piece has already zoomed in on Leon's eye. Then just after Leon says "Care if I talk?" it cuts to a side angle as he says "I'm kind of nervous when I take tests." This view shows Leon is looking towards the wall at a 90 degree angle away from the VK, meaning the view screen and eye piece could not have been seeing his eye at a frontal view as show in the previous shot. (00:05:15)
Continuity mistake: After he finds dead Pris, the blood smears on Roy Batty's lips change. He touches her bloody wound with the fingertips of his right hand and then presses them to his upper lip. You will see two parallel smears of blood. Moments later there is only one smear going from his upper lip all the way to his chin. (01:37:20)
Continuity mistake: When Deckard shoots Zhora, she crashes down through a glass wall and her cape is rolled over her head; in the next shot, In which she's crawling on the floor, her cape is straight behind her back. (00:58:00)
Continuity mistake: When we first see Deckard he is sitting down and reading a newspaper. After a little bit of time a seat becomes available at the restaurant across the way. The cook calls him over. Deckard then folds the newspaper once and places it over his head to shield himself from the rain. We see him run across the thoroughfare and off camera. It then cuts to him making his last couple steps to the waiting seat and the newspaper is now folded twice. (00:09:00)
Continuity mistake: As Deckard is giving Rachel the V.K. test, it shows that her eyes are a shade of green. Her eyes are actually dark brown. (00:20:15)
Continuity mistake: When about to question Leon, Holden asks him "Please don't move." When he does, his right arm is up and he points at Leon for a moment. It then cuts to a close up of the VK and suddenly his right arm is down in front working on the VK. The folding black flap things on the VK are also suddenly up and moving where they were not in the previous shot. (00:05:20)
Continuity mistake: As Deckard steps off the trolley when he is chasing down Zhora, a guy with weird sunglasses having flashing lights all over it bumps into him. The next shot is from a different angle, and that guy has vanished. (00:57:05)
Continuity mistake: After Leon puts his hand in the freezing liquid holding the eyes, warranting several angered scolds from Chew, Chew looks at Roy in puzzlement. Between this shot and the shot after Roy says "Yes... Questions." The head gear on Chew's head moves up on his hat. The position of it changes several times during this scene. (00:28:40)
Continuity mistake: After Gaf takes Deckard to his police car to go see Captain Bryant, he looks at a screen that is blue, then turns red and says PURGE. He looks down and to his right when he sees this. Moments later as they are flying in the vehicle, a view from the back seat shows the front dash with two screens. The one in the center, which would have been the one he was looking at since he was looking down to the right, is now much skinnier than it was moments before. It's the one showing green and orange text now. (00:10:25 - 00:11:10)
Continuity mistake: Just before Roy kills Tyrell, he says "Nothing the god of Bio-Mechanics wouldn't let you into heaven for." A drop of sweat begins to hang down off Roy's nose, about to fall. The camera changes angles and suddenly the drop has vanished. (01:25:35)
Continuity mistake: As Deckard is setting up the VK to test Rachel, one shot shows him adjusting the eye piece with his thumb as she asks if she can smoke. The view from behind his hand shows his thumb up towards the top of the eye piece. But then the film cuts to a view of the other side and Deckard's thumb is now towards the middle of the eye piece. (00:19:55)
Continuity mistake: While waiting in the rain for his food, the chef across the street calls Deckard to come over. Deckard folds his newspaper and puts it over his head to shield himself from the rain. The paper is folded messily and the crease side is in his hand. When he gets to the other side of the street, the fold is suddenly much cleaner and neat, and the crease side is on the outside, no longer in his hand. (00:09:00)
Continuity mistake: When Zhora collapses after being shot by Deckard, her legs are spread apart, but when Deckard approaches seconds later, her legs are suddenly together.
Chosen answer: The language is Chinese Cantonese, and is saying something like "... Now we can more time.", and when the replicants came inside the lab he says "... What a f*** doing here..."
