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.
Revealing mistake: In the shot of the Terminator skidding down the street after being rammed by the pick-up, it is a dummy. It's even missing a hand.
Audio problem: In every version of the film from the 2001 DVD onward, Kyle's shotgun has two completely different firing sounds in separate scenes. In the parking garage shootout, it sounds muffled, whereas it didn't sound that way in Tech Noir.
Continuity mistake: When Schwarzenegger runs the car into the wall, then goes to a room to patch himself up, he's wearing a grey jacket. When he leaves, he's now wearing a leather jacket.
Plot hole: When Arnie is driving the cop car and shooting at Conner and Reese, 5 or 6 inch holes from the gunfire are shown in the door right beside Connor. If the shell penetrated the steel door (which it could easily do - and was shown to do), there's nothing inside the door or on the other side of it to stop the bullet. Connor, and probably Reese, would've been ripped to shreds.
Factual error: When Kyle is hot wiring the car he touches 2 wires together and you can hear the starter trying to start the engine. This indicates the wire is controlling the starter. Then he takes the starter wire and twists it onto the other wire, keeping them together. If you really did this the starter would be permanently turned on and grinding on the flywheel. In reality, you would hold the 2 wires together until the engine starts, then disconnect them.
Revealing mistake: After Reese blasts the Terminator with his shotgun while at the Tech-Noir nightclub there should be huge holes in the Terminator's shirt and jacket, but there are none.
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.
Revealing mistake: Just before the tanker blows up near the end, there is a scene of it turning to hit a vehicle. The cable pulling the truck is visible.
Continuity mistake: When Reese and Sarah are fleeing from the Tech-Noir nightclub, right when the Terminator jumps on the car they're driving away in his hairstyle magically changes.
Continuity mistake: When Reese and later the Terminator go through the phone book to locate Sarah Connor, the second Sarah is listed as Sarah Ann Connor. Later, when Traxler and Vukovich are discussing the death of the second Sarah, Traxler reads the name on the police file as Sarah Louise Connor.
Suggested correction: A similar mistake was already corrected. When Vukovich says "girl number 2", he says she was killed earlier this afternoon, not that she was the 2nd victim. Sarah Louise Connor was shot first.
While Sarah is having pizza in a pizza place, the reporter confirms that "2 hours earlier" Sarah Ann Connor was the second victim.
Continuity mistake: The number 1874 is on supposedly different patrol cars driven by the T-800 and the police officers.
