Audio problem: In every version of the film from the 2001 DVD onward, there is a noticeable audio difference with Kyle's shotgun between scenes. In the parking garage shootout, it sounds muffled, whereas it didn't sound that way in the Tech Noir.
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: When the Terminator steps into the house to kill Sarah Connor he walks over the thresh-hold however in the next shot he is outside again. (00:16:15)
Continuity mistake: After the Terminator discovers Sarah's mother's address in the little address book of Sarah's, the next shot shows the Terminator leaving his room and going to Sarah's mother's. In that track shot down the hall look at the Terminator's shoes. He's wearing white trainers instead of the black boots he wears for the whole other time in the film. (01:14:40)
Continuity mistake: 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. (00:52:35)
Continuity mistake: When Kyle and Sarah leave the motel in the pickup, they ram the Terminator before they go, and you can see the bull bars on the front are damaged. When the camera shows the front of the pickup during the tunnel chase sequence, the bull bars are undamaged. (01:20:25 - 01:22:00)
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. (01:21:40)
Revealing 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. (00:48:10)
Continuity mistake: The Terminator loses the flesh around his left eye early on, but at mom's cabin you can see his backlit left eyelash blinking. (01:16:50)
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)
Character mistake: When the Terminator walks into the gun store, the "Clearance" sign in the window is misspelled "Clearnce." (00:13:40)
Audio problem: Early in the film, when the punks 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." If we look more closely, he actually says "My fu***ing turn." (00:05:10)
Revealing mistake: 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. (01:00:45)
Suggested correction: He's definitely not giggling and I wouldn't call it a smile. Maybe he's grimacing, but I seen him just wincing at the situation he's in. At best you could say he's a bad actor, but poor acting isn't a valid movie mistake that I know of.
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)
Visible crew/equipment: When Schwarzenegger rises to his feet after getting blasted out the Tech Noir window, a stage light can be seen behind him in the top right corner. (00:36:50)
Suggested correction: No production vehicle is visible and that definitely is not a stage light.
There is a stage light top right corner of the screen behind a black square light blocker.
I just watched Tampa Jay's filming locations video on this film. It's just a funny-looking street post across the street from the Tech Noir. Not a piece of filming equipment.
Revealing mistake: In the scene were Kyle and Sarah are speeding away from Arnold in the truck, Arnold starts shooting the truck with Kyle driving. When Sarah and Kyle decide to switch (passenger, driver), the camera shows them switching but there is a stuntman in place of Kyle. If not he has gained some weight in the cheeks and grown a big mustache during the course of 2 seconds. (01:24:30)
Suggested correction: This scene don't have cuts. In this moment, a shadow covers the face of Reese, causing confusion, but still be Michael.
No, it isn't. It is too obvious that he is a stunt double.
This is a continuous shot. Where and how would they have made the switch?
After Biehn says "trade places", there's a cut. The mistake seems to be saying from that moment it's Biehn's double. And before the two switch seats, there's another cut of the Terminator shooting at them. But I don't think it's a stunt double because typically scenes filmed from the perspective of the hood are done with the camera rigged to the vehicle and the vehicle is being towed, so the actors aren't actually driving, so there would be no need for a stuntman to do the seat switching.
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)
