Continuity: When the semi truck hits the parked blue AMC Gremlin car, the force of the crash switches the lights off, but when the truck is then blown up, the lights are back on again.

Continuity: Every shot of the semi truck shows it has single round headlights, but after it's been blown up and the Terminator falls out of the cab, you can see that the truck has now got twin round headlights.

Continuity: When the Terminator goes to kill Sarah in Technoir, the camera does a POV shot of the Terminator looking down at Sarah, and Sarah looking directly up at him. The immediate next shot where Kyle Reese is about to shoot the Terminator shows the the position of the Terminator and Sarah is different to the POV shot we saw before.

Revealing: In the scene where Arnie is being pulled under the semi-truck, his foot is caught and the green-colored dummy leg is revealed. It can't be a special effect sock since green screening was not in practice in the early 80's.

Revealing: The second future war segment: During the wide shot where Kyle and the female soldier are following the HK Tank, most of the plasma shots fired from said tank seem to come from above the gun turrets and not out of the barrels.

Audio problem: Early in the film, When the thugs 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." Yet, if you look he mouths "My fu***ing turn."

Revealing: When the Terminator invades the police precinct to kill Sarah, there is a part where he shoots a cop in the butt with his shotgun (right before he short circuits the building's wires). If you pay attention, the cop is smiling and giggling as he takes cover - before he is blasted.

Continuity: Just before Kyle exits the car park, he rams the police car driven by the Terminator into a parked car, and you can see the front left corner of the police car is damaged. In the next shot when you see the police car exit the car park, the damage has gone.

Visible crew/equipment: When Kyle and Sarah escape in the pickup truck, the Terminator chases after them on a red motorcycle. The camera does lots of shots of what's behind Kyle and Sarah and what's ahead of them. When they overtake a truck, you can see headlights following and shining on the back of their pickup. These are the camera crew's lights, as the Terminator's motorcycle is too far away, and previous shots have shown there are no other vehicles around them.

Continuity: Throughout the car chase shots where the Terminator is in the stolen police car, the car's rear view mirror is round. After the car crashes into the wall in the tunnel, the rear view mirror is square.

Revealing: "Dead" Kyle Reese is still breathing.

Continuity: In the scene in the apartment, where the Terminator cuts the flesh away from his damaged eye, he picks up a hobby knife that has a blade attached. In the next shot, as he lifts the knife up toward his eye, the blade has disappeared. Then in the front-on shot the blade is back again.

Continuity: When the Terminator is crawling after Sarah Connor at the end of the film there is a close up of the endo-skeleton and the hydraulic cables from around his shoulders are missing.

Revealing: After Reese finishes battering the Terminator with the pipe, the Terminator strikes back at him. Just before the camera angle changes to show us the pipe dropping on the floor, we get a close up of Reese's face. It is a stunt man, not Michael Biehn.

Other: As the Terminator is approaching Sarah in the Tech Noir nightclub, several other patrons can be seen behind her sitting in booths. These same people are in front of Kyle (he pushes them out of the way to get to Sarah before the Terminator does), yet he's on the other side of the club by the bar.

Visible crew/equipment: When Schwarzenegger rises to his feet after getting blasted out the window, a production vehicle and a couple of huge stage lights behind him are visible.

Deliberate "mistake": After the Terminator (in his police car) discovers Reese and Sarah in the car park, Reese hot-wires the car and starts to speed away. After that, there are several shots of Reese driving the car. It is easy to see that it's not Michael Biehn, but a stunt double who doesn't resemble Biehn at all, and who is seen in several other shots during the movie.

Continuity: When The Terminator is searching through Sarah's address book in his apartment he has flies on him. There is one on his forehead, but when the janitor knocks on the door, the Terminator turns his head towards the door and cusses at him but there is no fly on the forehead. When he turns back and continues reading the fly is again on his forehead at the same exact place on the forehead.

Continuity: In the factory, when Reese yells at Sarah to run and then turns and starts bashing at the Endoskeleton with his metal pole, if you watch carefully you can see that his fourth blow snaps one of the head supports. Yet we see a closeup of the head during his fifth blow, and the support is fixed again.

Continuity: The Terminator loses the flesh around his left eye early on, but at mom's cabin you can see his backlit left eyelash blinking.
