Audio problem: When the Terminator first arrives in 1984, the whole time displacement sequence (or whatever you want to call it) is witnessed by a garbage truck driver who mutters 'What the hell?'. His mouth however is obviously saying something else which has been dubbed over. (00:04:00)
Audio problem: Early in the film, when the punks are at the park, one of them is looking through a telescope and the other one breaks an alcohol bottle over it and says "Hey, it's my turn." If we look more closely, he actually says "My fu***ing turn." (00:05:10)
Audio problem: When the terminator smashes the car window, the crash sound occurs before his fist actually makes contact. (00:12:35)
Audio problem: When the Terminator breaks into the police station, he has a Franchise SPAS 12 semi-automatic (or selectable pump action) shotgun in his left hand, and an Armalite AR 180 machine gun in his right. Before he kills the power in the building, he comes to the end of a hall, points his shotgun through a doorway, and shoots. A machine gun sound is used for the blast, instead of a shotgun sound. (01:00:28)
Audio problem: Towards the end of the movie, after the tanker is blown up with the terminator inside, Sarah and Kyle are relieved that he is finally 'dead'. When the terminator gets up from the huge fire in his metal form, Sarah screams twice, however when she screams the second time, her mouth doesn't actually move. (01:30:10)
Audio problem: In every version of the film from the 2001 DVD onward, there is a noticeable audio difference with Kyle's shotgun between scenes. In the parking garage shootout, it sounds muffled, whereas it didn't sound that way in the Tech Noir.
Answer: Its simply a child being a child and playing, but more than anything, showing the innocence of the children that inspite of the near death of the human race all around them, there's still time to play and be... human.
