Audio problem: When the Terminator breaks into the police station, he has an auto-shotgun in his left hand, and a 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.

Audio problem: When Nighthob and Teeny are talking to the Rockbiter near the beginning of the film, Teeny says to Nighthob "This could be serious", then turns to Rockbiter and calls out his name. Watch Teeny's mouth as he calls out "Rockbiter". You will see a very blatant editing mistake as Teeny is not actually saying 'Rockbiter", but is saying the next line that follows. (00:16:40)
Audio problem: When Jack digs for the statue in the puddle, and he hits it, it makes a sound like iron against ceramics, but the bunny statue is wrapped in hay and cloth. The wrapping is so thick that the spade would not be able to touch the statue, so it would make no sound at all when he hit it with the spade.
Audio problem: When the geek and the prom queen are cruising down the road in the Rolls Royce convertible, the drunken prom queen says to the geek "Looks like rain, better put the top up." However, her mouth movements do not match the words.
Audio problem: During the song 'Found A Job' (about 30/60 secs. in?) a cymbal crash can be heard, but the drummer doesn't hit a cymbal. Later on, the error is reversed (drummer hits cymbal but no crash is heard).
Audio problem: When Alex and Maggie are going back into space at the end, everyone moves back and they yell goodbye. You can hear Otis say goodbye, but his mouth does not move at all.
Audio problem: In 1943, a top secret Naval experiment went wrong and David was sent forward in time to 1984, with his friend Jimmy. In 1984, David and Allison, a girl fom the present day, are staying in a hotel room. David picks up the talking travel alarm clock and fidgets with it. Yet, in the shot of Allison the alarm clock is still on the nightstand between the two beds. Then as he puts the alarm clock back on the nightstand, in the shot of Allison, the alarm clock is on the nightstand even though we hear the sound of him actually placing the alarm clock down.
