Continuity mistake: When Leon goes to sit down for his test, he appears to be wearing a name tag that is attached to the left breast of his outfit. Once he sits down, you only see the printing on the shirt. (00:05:00)
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: The dialogue between Holden and Leon in the beginning never matches the interrogation tapes during the films (excluding Deckard's recall a moment before he confronts Pris). Most notable are the time and speaking manner. It can be heard when Deckard and Bryant listen to the tape. (00:05:35 - 00:13:35)
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: 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: The Asian chef calls Deckard over to order his food once a seat becomes available. There is a guy in a yellow shirt sitting next to the open seat. A blue bottle of some sorts is right next to this guy's arm. When Deckard comes over, the blue bottle has vanished. It appears again once Deckard sits down to his left by the yellow guy's arm. And then after the chef gives Deckard his food, the blue bottle is suddenly on Deckard's right. (00:09:05)
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: 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: 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: 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 Pris and J.F. Sebastian startle each other, they begin to talk for a moment. Watch J.F.'s hands as he says "Don't worry, I won't hurt ya." In the side angle, his left hand is hidden and his right hand is fidgeting with the bag he is holding at his chest. It then cuts to a view from over Pris' shoulder and suddenly his right hand is now hidden from view and it's his left hand fidgeting. (00:39:00)
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)
Continuity mistake: When Deckard is snooping about in Zhora's dressing room asking questions. We see her putting on high heel mid-calf boots (just under her shin pads). Watch the chase sequence soon after. Especially when she gets shot and is on the ground picking herself up, you can see she is wearing what looks like black trainers. (00:52:10 - 00:55:40)
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: When Decker shoots the snake-woman replicant, she hits the glass and in one shot you can clearly see that is not the actress that hits the glass, but a stuntperson dressed like her. This has been corrected in the 2007 Final Cut of the film, but exists in all previous versions. (00:57:50)
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 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: 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)
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: Just after Rachel asks Deckard if he ever took the VK test himself, she walks in after no response and sees that he has fallen asleep. Before the camera shows him sleeping, she is shown walking into the room, clutching a drinking glass with both hands in front of her. The camera switches to Deckard for a couple seconds, then back to Rachel. She is standing in the same spot, with no immediate area to set the glass down at, but her pose has completely changes where she has one hand on one hip, and the other arm limp at her side. At which point she then reaches forward with her left hand to grab a picture off the piano, and the drinking glass has vanished. (01:07:50)
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..."
