Continuity mistake: At the very beginning of the film when we see the garbage man picking up the steel bin with his forks, if you watch closely you can see the shadow of the large forks pass the windscreen, yet in the following shots the forks are lower than the windscreen. (00:03:50)
Continuity mistake: Two large railings can be seen curving around the building corners when the cops arrive at the alleyway to pursue Reese. Those railings weren't present in the shot preceding Reese's arrival; the cops pulling up was filmed in a separate alleyway. (00:06:15)
Continuity mistake: 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. (01:28:45)
Continuity mistake: When the Terminator punches through the car window, there's broken glass all around the window frame. When he closes the door, there's only a little glass around the top of the frame. (00:12:55)
Continuity mistake: 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. (01:31:14)
Continuity mistake: 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. (00:35:30)
Continuity mistake: In the scene where Sarah and Kyle are escaping in the car they found in the alley after leaving the nightclub, Tech Noir, we see Arnie jump onto the hood of their car in flames. While he is in mid-air during the jump, he is on fire but as soon a he lands (the next shot) the flames are gone. (00:37:35)
Continuity mistake: 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. (01:37:15)
Continuity mistake: When the Terminator arrives at the first Sarah Connor's house, the address number is "14239", even though in the phonebook it is listed as "1823" (or "2816" or "309"). (00:15:15)
Continuity mistake: When Arnie says "I'll be back" and leaves the police station he throws both the doors open as he leaves one of them falls back into place but the other one stays open. When he drives his car through the window both doors are closed.
Continuity mistake: When Sarah is sitting in the bar after talking with the police, there is a drink in a glass on the table in front of her. The scene cuts away and when it cuts back, it is a small bottle, not a drink glass. (00:33:45)
Suggested correction: When she sits down, there's two empty mugs and two bottles, but she doesn't have her own drink. The scene cuts to the Terminator coming in, and then we see her with her drink (a bottle and the glass). But enough time for someone to bring it to her.
Continuity mistake: When Arnie gets shot in the club after he gets up again there's no bullet holes in his chest or blood on his shirt. (00:35:50)
Continuity mistake: 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. (00:49:35 - 00:50:20)
Continuity mistake: 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. (00:48:30)
Continuity mistake: Early in the movie, prior to heading out to the bar where she first sees the Terminator, Sarah Connor is holding her iguana at her apartment while talking to her roommate. In the first shot, she is holding it with her left hand under the lizard's chest. The film cuts to a different angle, and now the lizard is resting against her shoulder, with Sarah's left hand on its upper back. It cuts back to the original angle and again her hand is supporting the chest. (00:23:25)
Continuity mistake: 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. (01:14:05)
Continuity mistake: In the tunnel scene we see Sarah drive past the 2 lorries. They then meet, making it impossible for the Terminator to get past. Angle changes and the lorries still haven't met yet. (01:21:00)
Continuity mistake: When The Terminator's stolen police car is shown up close in the parking structure, look at the police logo. After the car crashes, you can see the logo has flipped. (00:45:50 - 00:50:20)
Continuity mistake: In the scene where Arnold is turning off the power in the police station he gets shot by a cop and jerks forward. But every other time he is shot he does not even twitch. (01:00:55)
Continuity mistake: When the Terminator is washing his face in the motel room after he was wounded during the chase, the tap's valve is showed in different positions between two shots.
