When Zhora smashed the glass, he obviously used a substitute, and he held the mechanism that detonated the blood bag in his right hand.
Price's hair was wet before entering the Bradbury Building, but when she walked into the building immediately, it became dry.
In a scene where Deckard fights with Prius, Prius is obviously wearing pantyhose in some shots, while in other shots, his legs are bare and there is sweat on his skin.
Judging from the photo, Zhora's tattoo was on her right cheek, but when she was hunted down by Deckard, the tattoo was on her left cheek.
When the images of Zhora and Prius first appeared, the explanation of the two identities was crowned.
In Dickard's residence, the color of the lipstick that Rachel wears changed between red and pink many times.
In the rooftop scene at the end of the film, it was raining when Brady released the pigeons, and then the sky was blue in the shots of the pigeons flying away, and there was no sign of rain. Ridley Scott later admitted that it was his own suddenness. Because the pigeon refused to fly in the rain when shooting this set of shots, he planned to make up the shots, but then he forgot about it.
The owls in the film make a flapping sound when they fly, but in fact this nocturnal raptor is extremely quiet when flying.
Bryant told Dickard that a total of 4 clones had escaped. A few minutes later, he said that a total of 6 people had defected. One of them was shot and the other was never explained in the film. It turned out that there was another clone character Mary in the script at first, but it was eventually not adopted due to time and funding constraints. According to the actor, the dialogue involving the number of people had been re-recorded at the time, but somehow the director did not use all of it in the end. Contradictory.
