Other mistake: It is established in the movie that whenever Joi is switched on through the emanator, or when she tries to communicate with K when switched off, a chorus line from the song Peter and the Wolf will play. This is shown at numerous points: when K first activates the emanator, when K is talking with Luv at Wallace Corporation, when K is talking with the hooker, when K switches her on when he is analysing the DNA, when she is reset after the car is shot down and when she switches herself on to tell the hooker to leave the apartment. However, when Luv is beating up K, Joi switches herself on to tell Luv to stop, but the chorus line from Peter and the Wolf is not heard, despite being heard every other time in the movie. (02:00:30)
