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.

Continuity: When The Terminator's stolen police car is shown up close in the parking structure, the motto on the left side of it reads "to care and to protect." After the car crashes, you can see the motto on the left side again, but this time it reads "Dedicated to serve."

Continuity: When the Terminator says "I'll be back" he walks out of the police station. The cop inside the building looks out the window, looks very surprised, and you can see the headlights from the car shining on the cop's face. But when we see the car just before it comes crashing through the building the headlights aren't on. In the next shot of the cop the headlights are still shining on him.

Revealing: At the end of the film just before the tanker truck explodes you can clearly see the tow rope pulling the tanker forward.

Continuity: In the Tech Noir Bar, the same woman - blonde with a pink or orange dress - must have come dancing with her twin, because while she's sitting behind Sarah Connor when the laser beam is pointed at her, she's also dancing near Arnie. The T-800 moves past her when he sees Sarah Connor and moves to shoot her.

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.

Visible crew/equipment: In the scene where Sarah and Kyle have run into the factory, the Terminator is breaking through the armour plated door. As the Terminator comes through you can clearly see the two operator guys crouching behind the model.

Continuity: Arnold looks up Sarah Connor's address in the telephone book. The telephone book address has 4 digits, but he goes to a house that has 5 digits on it.

Continuity: In the scene where the Terminator enters the police department and he bends over to say "I'll be back" you can see through his shades and he has both of his eyes, despite cutting one out in an earlier scene.

Continuity: During the scene when the Terminator is killing Sarah Connor's roommate and boyfriend, the sound of the phone being knocked around, enough to be off the hook, is heard. Shortly after the killings, a call (from Sarah herself) comes in and the phone rings until the machine picks up.

Visible crew/equipment: In the scene where the terminator is blown up inside the gas truck and you think it is destroyed, Linda Hamilton and Michael Biehn begin to hug. In the shot where the terminator begins to rise from the destroyed truck, look just a little to the right of Linda's head and you'll see a mans head pop up and his hands pull down on a lever that makes the terminator rise up.

Continuity: The telephone message left by Sarah's roommate changes the two times we hear it. The second time, there is no delay between "Hi there" and "ha ha ha fooled you", while the first time has a delay of over a second.

Continuity: During the final chase scene, Sarah loses control of the pickup and it rolls over, as it rolls you can plainly see that it has no engine.

Continuity: Early on in the film Kyle cuts the wooden handle of the shotgun with a saw, but then later on when they are in the car park hiding from the cops you can clearly see that the handle is back to its original size.

Revealing: When Arnie drives through the police station, the cop is just sitting there. Not only that, his skin is a lot paler. It is so easy to see that it is a dummy.

Revealing: When the Terminator's flesh is burning off in the burning tanker wreckage, you can see the wire moving the Terminator puppet around.

Continuity: When the tanker explodes near the end, the Terminator gets out of the truck on the left-hand side of the cab, and falls to the ground. When the endoskeleton arises minutes later, however, it is on the opposite side of the cab (Sarah approaches Reese from the right side, and the endoskeleton arises in the background).

Revealing: Watch the third 'future flashback' sequence carefully, particularly any shots that show Kyle charging towards the Terminator firing that oversized plasma weapon. There are at least two instances where you can see plasma bolts going straight through Kyle's body and impacting behind him.

Continuity: At the start of the film when we first see Reese arriving, the drunk homeless guy is holding a bottle in his left hand, then the camera continuously switches between Reese's arrival and the old guy, in these shots, the bottle keeps changing hands from left to right, then back to left.

Deliberate "mistake": After Reese rams the Terminator with the pick-up truck, the truck starts to back up out of the motel. The Terminator gets up and runs after it. Just before the shot changes, you can see that the truck still hasn't left yet. But when we cut to the Terminator getting on his motorcycle, the truck has disappeared. Considering that Sarah and Reese are in a huge pick-up truck, it is highly unlikely that they could have traveled that far in a short period of time.
