When Sarah is in the night club she has to put change into the pay phone to call 911. While 911 calls are free, many pay phones in the 1980s required you to insert a coin in order to obtain a dial tone.
At one point during Reese's explanation, Sarah begins to say "Ky..." and then stops herself. Linda Hamilton obviously forgot that Sarah doesn't ask Reese's first name until much later.
Just before the Terminator kills the power to the police station, he comes to a door at the end of a hallway. He fires his shotgun, but we hear the sound of the machine gun instead.
Just before the car crashes into the police station, the officer at the desk is alerted to the car by the headlights flashing in his face, yet when we cut to the car, the lights are off.
Before the TechNoir scene, Reese pumps his shotgun at least twice, which would load a shell into the chamber and make it ready to fire. But when he identifies the Terminator at the nightclub, he has to pump the gun again before firing.
When the Terminator is rising to his feet after getting blasted out the window, a production vehicle and a huge stage light are visible behind him.
Even with a taped-together pair of large-capacity magazines, there are far too many shots fired from the Terminator's machine gun at the police station.
When the Terminator tosses the bearded man away from the phone booth and begins searching the phone book for Sarah Conner, he uses his finger sliding down the page to assist separating the lines of type, the way human beings do when they read. Yet the Terminators have specially enhanced telescopic vision that allows them to zoom in/out, etc., on anything, even in the dark. It therefore makes no sense that this Terminator would have to use his finger to assist with his reading, he should be able to merely glance at the book and zoom in on the entire page, or on the smallest part of the page and process this information in seconds.
When Sarah is walking from her apartment you can hear the heels of her shoes hitting the pavement. Later when she's walking into the disco she's wearing tennis shoes.
The three "Sarah Connors" are listed in different sections in the phone book when Reese, The Terminator and Sarah Connor look them up (right page, left page, right page). They might have been different editions, though books at pay phones are generally all replaced at the same time.
When the Terminator is stalking Kyle and Sarah in his police car, the sticker on the driver's door reads "To care and protect". When the car is later wrecked in a tunnel, the sticker has changed to "Dedicated to serve".
The Terminator purchases firearms at a gun store, including a short-barreled, automatic Uzi. There are strict federal laws, and California has had bans on these for decades. No gun store sells them, and no criminal enterprise would have them readily visible on the wall. Converting a long barreled semiautomatic Uzi to full auto takes completely different internal parts, a machine shop and precise tooling.
Traxler allows Sarah to take a nap on the couch, and he tells Sarah her mother should arrive from Big Bear in about an hour. Shortly after, the Terminator arrives, and Sarah and Reese flee, all of this happening at night. Later, the car Sarah and Reese take runs out of gas, and they spend the night under a bridge. A short time later, it's light out, or the next day, and they make their way to the Tiki Motel. Sarah then gets on the phone, and we find out the Terminator is there, and has killed her mother, mimicking her to get Sarah to reveal her location. The question is, why would Sarah's mother still be at the cabin in Big Bear when she was supposedly on her way to pick up Sarah at the police station? No mention is made of her stopping along the way at a pay phone to call her, and there were no cell phones in 1984. It also takes a lot longer than an hour to get to get to Los Angeles from Big Bear. The Central Division of the LAPD is about 120 miles (190Km) from Big Bear, with the first 40 miles (65Km) which is on highway 38, a twisty two lane mountain road. It's closer to a 3 hour drive in all.
When the Terminator finishes punching the hole in the door to the computer factory and walks in, a puppeteer's head can be briefly seen behind him.
During the flashback scene in which a Terminator infiltrates the underground human hiding place and starts killing people, if you look at the right side (his right side) of the Terminator's face by his eyes, you can see a flat line which is part of the makeup used to give him his glowing red eyes (like the sunglasses with LED lights that were popular to wear in the 1980's).
As has been demonstrated on MythBusters: Brown Note, and re-confirmed in MythBusters: Mythbusters Revisited, Newton's Third Law establishes that bullets and shotgun blasts do not have the momentum to knock a human body backwards, although the trauma of being shot may cause them to fall backward. Since the Terminator is made of a solid alloy, is much heavier than a human, and cannot feel pain (confirmed by Reese), much less trauma, it should not react at all to being shot, much less be thrown backwards by the shotgun blasts in Tech Noir.
Thousands of rounds are fired by various automatic weapons and shotguns throughout the movie, yet none of them ejects any empty shell casings when they're being fired.
In some scenes, Reese has a clean shaven face. In others, he looks like he's growing a beard.
During the scene where the psychologist is talking to Reese, the attending police officer in the interrogation room has his sidearm on his hip. Police officers don't wear their sidearms when in an interrogation room with a suspect.
The number 14239 appears above the front door of the first Sarah Connor (a similar number 14329 appears above the entrance of the Alamo Gun Shop) but does not match any of the addresses for Sarah Connor shown in the telephone directory.
May 19th in 1984 was a Saturday not a Friday. (This error was due to the script of the film being written in 1983, and the film itself was to begin production that same year, but ultimately was postponed because of Arnold Schwarzenegger's commitment to finishing another project at the time. When it was decided to have the film set in 1984, the writers chose not to change the day of the week.)
As Kyle and Sarah are sneaking toward another car in the parking garage, a police car with the serial number 1874 drives by. The number 1874 is also visible on the Terminator's police car. The first car that drove by couldn't have been the Terminator's because a second cop is visible in the passenger seat.
During the gun shop scene, the Terminator asks the clerk for a 'phased plasma rifle', presumably a weapon from its own time (2029). Some claim that the Terminator, as an advanced infiltration unit, should have had detailed files on the current time period. Therefore it should have known that the plasma rifle did not exist yet in 1984. However, as Reese explained, most of the records were destroyed during the war. Skynet knew very little about Sarah Connor, apart from her name and city in 1984. It therefore doesn't seem unlikely that the information on weapons availability in the 20th century had been lost as well. The 'phased plasma rifle' may have been an earlier version of the energy weapons seen in 2029, something that might have existed in the late 20th century, so the Terminator just tried if it was available.
When the Terminator stumbles out of the burning cab, he collapses and burns in the fire. Its skull is clearly shown burning with no internal machinery. Later, when it rises out of the fire, it does so from underneath wreckage of the cab. These two inconsistencies have led some to erroneously believe that there was someone else in the truck.
Kyle would not have told Sarah to screw the end cap onto the pipe bomb till he had the fuses ready, since he would have to insert the fuse in through the cap and into the explosive paste.
As Vukovich is rushing toward the auto-weapons storage room, the camera light is briefly visible on his back.
At the beginning of the film, the garbage truck driver's mumblings are completely mismatched from his lip movements.
The Terminator was sent back through time to kill Sarah Connor and thus prevent the birth of John Connor, its enemy, who destroys it. The film clearly states that the records from that time period are sketchy due to "Judgment Day", the nuclear attack launched by Skynet, the artificial intelligence which created the Terminators, to destroy humanity.
Several problems arise from this:
1) At the time of the film, roughly 3 million people lived in Los Angeles proper, with almost 11 million living in the metropolitan area. That would likely mean that there could be as many 100-300 woman with the same name the Sarah Connor that the Terminator was seeking. Was the plan to kill ALL of them, hoping that the Terminator would get the right one? As the film shows, this simply alerts them of the killings and causes them to flee which itself would have foiled the plan. 2) How or why did Skynet believe that "Sarah Connor" was even her real name? Given that the primary industry in Los Angeles is entertainment and people often change their name for performing purposes, it should have been obvious even to an artificial intelligence that her name may not have been Sarah Connor after all. 3) The Terminator uses a phone book to search for Sarah Connor. Besides her possibly having her number unlisted or even not having a phone in her name, this would actually been the worst way to search for someone, even in 1984. Since the Terminator itself is an android with a computer brain, why didn't it attempt to tap in to the extant databases at the time and search in that manner? 4) Skynet, despite being shown as being far more intelligent than human beings, seems to never consider that Sarah Connor's living in Los Angeles might simply be a disinformation campaign to disguise the her true location in the past.
Kyle Reese and the human resistance know a great deal about Skynet's plan to kill Sarah Connor in the past. Since there's no need for Skynet to write such a plan down or to even store it in its memory banks, how could they have discovered it? Even worse, the majority of the information actually seems to have come from John Connor's memories of what his mother told, despite the fact that she definitely would only possess the barest sketch of what Skynet had planned with most of that coming from Kyle Reese who in turn was told what he knows by John Connor.
Cutting the power in the electrical box would not cause the florescent lights to come apart and explode; they would just go dark. The Terminator doesn't cut the power - he actually surges the lights with the wire from the high-voltage box. A high voltage surge like that could definitely cause fluorescent lights to explode, if they got hot enough.
When the terminator talks to the desk officer, you can see through the glasses which shows both his eyes intact, even though one should be missing.
Obvious stunt double for Kyle when he and Sarah are switching sides in the pick-up truck.
When the Terminator is shooting Ginger, he can clearly be seen closing his eyes with each shot. The flash of the gun should not affect the Terminator.
After Reese and Sarah Connor flee the police station, Reese is bleeding from a bullet fired by the Terminator. While the car's windows were not broken during the gunfight, the driver's window is either rolled down or missing, and he could easily have been hit through it - or indeed he may even have been hit by a stray bullet while making his way through the police station, which, throughout the Terminator's attack, is riddled with gunfire.
When Sarah is first holding the iguana, she is holding it across her body, the shot then switches to a head-on and the iguana is resting on her shoulder. It then switches back to it's original position.
When the Terminator punches the windshield he shatters it completely, but in later scenes there is only a fist-sized hole in the windshield.
When the Terminator is heading into the gun store, there is a sign on the glass that says "Clearnce Sale".
Near the beginning of the police station shoot-out, the Terminator fires his shotgun a few times, but the sound effect of his assault rifle is heard.
When Kyle rescues Sarah (during the police station massacre), he screams "Sarah!" loud enough for anyone nearby to hear it. However, this does not draw attention to the Terminator himself, allowing Reese and Sarah to make their escape.
The same woman - blonde with a pink dress - appears simultaneously on the dance floor at Tech Noir and behind Sarah as the laser beam is pointed at her.
During Reese and Sarah's car swap from the Ford LTD to the Eldorado, Reese hits the ignition with the butt of his shotgun and the ignition tumbler suddenly loosens. This is impossible. Reese would have only knocked the chrome fob off. The tumbler itself can only be removed if a hardened bolt is removed that is inserted through the tumbler itself that both locks the tumbler in place and stops the tumbler itself from twisting when you start the car.
At the beginning of the film, when Reese aims a gun at the police officer and demands to know the date, the officer tells him it's May 12. The first scenes with Sarah, which take place later that same day after sun-up, show her clocking in at the restaurant where she works. The date on her time card reads May 19.
In the factory scene after Reese blows the terminator's legs off, Sarah discovers a cylindrical piece of metal has been driven into the calf of her left leg by the explosion. She pulls it out. In reality, it would easily have penetrated her left femoral artery and pulling it out would have resulted in Sarah exsanguinating in a matter of minutes.
In the final scene the boy in Mexico asks for "cincos dolares" [stress on the a]. That's incorrect Spanish for native of Mexico, even a child. It should have been "cinco dólares".
When the Terminator drives the car into the police station, the desk sergeant who gets crushed is obviously a dummy.
Sound synchronisation wrong when Kyle and Sarah are getting up to escape from the Terminator robot, arising from the flames Sarah's screams are not matching her mouth actions
In the future human hideout, some children are watching a hollowed-out TV with a fire burning inside it. But even a small fire would cause heat accumulation at the top of the cabinet which would melt and/or ignite it within minutes.
Obvious dummy for the Terminator when he is sliding on the asphalt after getting hit by the pick-up truck.
At the end of the film, the paramedics load Sarah into the ambulance feet first. Paramedics always load a victim's body head first.
The wire pulling the tanker truck is visible several times.
The bandage on Reese's right hand disappears when he and Sarah climb into the black pick-up truck. During the following chase, it is back on his hand.
When the Terminator skeleton rises out of the flames, a silhouette of a crew member can be seen behind the flames, rising from a crouch to pull a big lever. As the lever comes down, the metal skeleton rises up.
When Sarah is in Tech Noir walking towards the phone, she passes a man in a blue vest with a blonde mullet. In the next shot, she walks past him again, now in a entirely different spot.
Just before the Terminator crashes his car through the police station door, the officer is writing on a form with his left hand on the table. In the next cut he has his left hand on the form. The position of the pencil also changes in the two shots.
Sarah picks up the second pipe-bomb casing to fill it, yet it is clearly already full of the plastique paste.
The face of Michael Biehn's stunt double is clearly visible for an extremely brief moment (noticeable only by using super-slow motion) at the end when the endo-skeleton is smacking Reese around. He is seen, for an instant, right before the Terminator knocks the steel bar out of his hands. It is not known who the stunt double is.
The human resistance uses the time machine created by Skynet to send Kyle Reese into the future. However, despite having no reason to do so and using the coordinates inputted by SKynet, he arrives well AFTER the Terminator does. If anything he should have arrived simultaneously or very shortly afterward (within seconds or minutes)
As the tanker truck is pursuing Sarah near the end of the film, the parked car that the truck smashes is already badly damaged from a previous take.
When Det. Vukovich laughs at Dr. Silberman's ray gun joke, he can be seen reacting to an off-screen crew member who must be gesturing for him to stop looking at Sarah Connor and back to the video monitor.
Reese and Sarah ditch an AMC Gremlin after the police station massacre, and they then sleep under a bridge nearby. Despite possibly being exhausted, it seems like they're leaving themselves open to attack by the Terminator by leaving the car in the nearby woods, then sleeping near it. The Terminator could certainly have decided to travel down the same road they did, and possibly have found them.
When Sarah tries to escape from Reese in the first car chase, he grabs her by the hair. His grip on her (grabbing her hair, pinning her to the seat with his arm, shoving her head to the floor, or not holding her at all) changes frequently during the chase.
The tanker truck has single headlights. When the terminator jumps out of the burning wreck, the semi has twin headlights.
After the Terminator finishes operating on himself and puts on the sunglasses, he only has a shirt on, but when he walks towards his bed to get the guns from underneath the mattress, he is suddenly wearing a leather jacket.
"Dead" Kyle Reese can still be seen breathing and moving his eyes.
The broken window in the Gray Ford changes sides during the movie.
At the factory, when Reese is fighting the terminator with a metal rod, an obvious stunt double for Reese is being used, particularly when the Terminator backhands him in the face.
During the second car chase, there is a burst of smoke from the Terminator's shotgun in one shot, but no sound effect.
If the Terminator can imitate anyone's voice, why doesn't he just do that all the time?
When Reese tosses the third pipe bomb, we can see that the pick-up and motorcycle are almost at the end of the tunnel. But when Reese tosses the fourth bomb, the two vehicles still have a long way to go. After the fourth bomb explodes, the truck and motorcycle have cleared the tunnel.
When the Terminator gets into the tanker truck, there is a close-up shot of his left hand grabbing onto the type of door handle that protrudes from the door, and pushing the button on the handle with his thumb. But when the Terminator is chasing Sarah and Kyle with the truck, the door handle is the rectangular type that is recessed into the bottom right corner of the door.
When the Terminator's flesh is burning off, a wire is clearly visible moving the Terminator puppet around.
The phone number that Sarah Connor gives the Terminator (impersonating her mother) for the Tiki Motel, where she and Kyle are staying, is 408-555-1439. However, after the Terminator hangs up with Sarah, we see him dial 555-1639 and get an answer from the Tiki Motel.
When Sarah realizes that despite being burned, the terminator is still alive, you can hear her screaming "No, no!". It's obvious that she's not actually screaming the second "No!"
Amount of time between Sarah dialing phone at Technoir to the time of answering machine pick-up.
Stage lights visible in Sarah's sunglasses when she puts them on and drives off at the end of the movie.
The Terminator punches the door window of the car, some broken glass hangs in the window. As the Terminator is sitting in the car, the broken glass disappears in the next frame.
When the Terminator is using the knife to cut away his eye, from the side view, there is no blade in the knife.
During the police station massacre, just before the Terminator shorts out the lights, he shoots a policeman in the back. The policeman is clearly seen smiling just before he starts to flee from the Terminator.
The police car that the Terminator steals has neither a rear-view mirror, nor a partition between the front and back seats.
The rear-view mirror has been removed from the Ford that Reese steals.
During the police station massacre, the camera is positioned on the floor, and shows the Terminator shooting through a door on the left. As he fires his gun, the supposedly dead cop in the foreground can be seen to jump.
Tanker truck obviously being towed.
The message on Sarah's answering machine goes, "Hi there... Ha-ha, fooled ya. You're talking to a machine..." with a pause between "Hi there" and "Ha-ha". When the Terminator has shot Ginger, the answering machine starts and we hear the words immediately following each other. Also, when the police call Sarah's apartment, the message changes/speeds up; it is much quicker.
Reflected in Sarah's sunglasses when she puts them on just before driving off at the end of the film.
When Sarah is put into the ambulance, the boom microphone is briefly reflected in the left rear window.
Obvious stunt double for the Terminator when he pulls a sharp u-turn in the police car.
Just after the car chase leaves the parking garage, one shot is obviously sped up.
Both Reese's and The Terminator's outfits change inexplicably throughout the film. Reese first steals a pair of trousers and then a long gray coat and a pair of sneakers, but in the next scene he is shown also wearing a T-shirt. The Terminator wears a military style jacket for the first part of the film, but when he returns to the apartment to "operate" himself he is wearing a leather jacket which he keeps wearing for the rest of the film.
May 12 1984 fell on a Saturday and not a Thursday, like a police officer tells Reece near the start.
Without no reason The Terminator at 39:48 has no eyebrows for couple of scenes following. Later on he has eyebrows again.
As Sarah Connor is being wheeled out of frame(close up)by the paramedics and she is looking at Reese's body, her mouth isn't moving but her voice on the soundtrack is heard saying "Kyle..."
An easily audible ripping sound is heard when the Terminator tries to drag Sarah out of the car by her shirt, yet in subsequent shots, her shirt is undamaged.
During the chase with Reese and Sarah in the Eldorado, the police car the Terminator is driving is forced onto the sidewalk, at which time the same car passes by in the opposite direction three times.
When the Terminator crashes the car into the front of the police station, you first see the lights of the car light up the desk sergeant. As we see next, the car approaching outside the doors doesn't have its lights on.
As the Terminator walks toward the wall at the Griffith Park observatory, the shadow of the camera can be seen on the far left of the screen before the shot ends.
The scene when the terminator is removing his damaged felt eye in the mirror he's shown removing it from his right eye. Even after the terminator removes it when it shows the cyborg's eye on his right eye in the mirror.
In the beginning of the movie The terminator had full eyebrows but a couple of minutes later they were hidden with makeup.
Reese starts the car by twisting the starter wires together; this is incorrect. The "run" wires (these get connected when the key is in the "run" position to allow the spark plugs to fire; they get disconnected and stop the engine when the key is turned off) get twisted together, but the starter wires are just temporarily held together till the engine is cranked and started; they are not connected continuously to keep the engine running.
Reese touches two of the wires together to make the car's engine crank briefly, yet when he re-connects them and twists them together (which he would not do in real life to hot-wire the car; only the "run" wires get connected "continuously"; the starter wires just get connected temporarily till the engine cranks over and starts), the starter is only heard a long moment later.
None of the addresses in the phone book that the terminator consults for "Sarah Connor" match the address above the door of the first Sarah Connor he visits and kills.
The black pickup truck that Sarah rolls onto its roof appears soon after undamaged.
When the Terminator kills the first Sarah Connor, he comes through the door and extends his gun arm fully. After a brief cutaway he fires, but he is now behind the door frame and his arm is in a different position.
In Tech Noir, there is a man wearing a white and black tank top on the dance floor. In the next shot, the same guy is standing behind Reese as he's preparing to fire at the Terminator.
For the first few shots of the parking garage chase, an obvious stunt double for Reese is driving the car. Furthermore, there is no one in the passenger seat.
When the black pickup rolls over, it is obvious that it has no engine, transmission, or driveshaft.
In the second future war sequence, when Kyle Reese is with a female soldier and she gets blasted by a HK tank, it is obvious that it is a dummy with a poorly designed head.
After Kyle appears in an alley after traveling through time, he steals a pair of pants from a wino in the alley. Kyle has a slim, athletic figure, and the wino is a large man with a big waistline. Yet the pants fit Kyle perfectly.
In the shootout at the police station, the Terminator twitches in response to being shot while taking out the building's power supply, yet is not phased at any other point when he's shot, including by the police officers armed with M16 rifles.
Both Sarah Connor and Lt. Traxler state that the Tech Noir nightclub is on Pico Blvd. When Kyle and Sarah leave the nightclub, they briefly run down an alley, steal a car and flee the scene. As they leave, a policeman radios in a request for "an ambulance at 7th and Broadway" (erroneously thinking the Terminator will need medical attention). But in reality, 7th and Broadway is nearly a mile away from Pico Blvd. in Los Angeles, not nearby as would have to be the case for the movie sequence to make sense.
The position of "Pugsley" while Sarah listens to the telephone messages.
When Reese uses the final pipe bomb to blow the terminator in half, the terminator's torso can be seen moving as the pipe is placed, obviously made of plastic.
The sound of the car window being smashed by the terminator.
In the TechNoir club, the music changes between when Sarah gets her answering machine and when she hangs up.
As Sarah is talking into the tape recorder, the microphone is up to her mouth. As the boy takes her picture, the microphone is not visible in the photograph of her and her dog.
When Reese starts his explanation in the Ford LTD, he appears to have a brand new wound under his lower lip. When he continues his explanation in the other car (which is only a few minutes later) the wound has been healed and replaced by a scar.
Position of Sarah's right hand (on Reese's cheek) before she starts kissing him and when she is kissing him.
During the police station massacre, an officer shoots the Terminator in the chest before being killed. The bullet hole in the Terminator's shirt doesn't appear until a few shots later.
The events from the time Sarah and Reese arrive at the hotel until the love scene are all during the day. In the middle of this Sarah calls her mom's cabin and talks to the terminator. The shot of the cabin is at night, as is the following shot of the terminator riding his motorcycle. Then everything is daytime again until he arrives at the hotel.
In the chase with the gray Ford LTD, dents, and hubcaps appear, disappear, and reappear on the vehicle throughout the chase.
In the parking garage, when Reese and Sarah get into the car to steal it, Reese's coat gets caught in the door of the car and is pulled tight enough to restrict his movement. A moment later, the coat is free and loose around his neck.
We see Ginger walking back to the bedroom with a plate of food and a glass of milk. When Matt crashes through the door, Ginger tosses and drops the food. When Ginger is shot and is trying to crawl away from the Terminator, the food on the floor in the hallway had some how disappeared.
At the beginning of the chase with the Cadillac, bullet holes can be seen appearing in the front windshield several times, but during most of the chase, it only has one hole.
When Kyle and Sarah hit the Terminator with their truck at the Tiki Motel, the grill has significant damage. During the highway chase, the shots of the front of the truck show no damage to the grill whatsoever.
Sarah grabs Kyle's shotgun to stop him from getting out of the Cadillac. When the camera switches to the other side of the car, she is holding Kyle's arm, then she grabs the shotgun.
In the future scene where Reese and other fighters are just entering the underground 'base', you can see a camera crew off to the left as the scene pans out.
Sarah's two screams as the pick-up flips in the final chase scene are identical, and, most likely looped.
Before Sara closes the cage-like door at the press, a silhouette of the Terminator's legs can be seen in close-up, even though they're supposed to have been blown off.
In the TechNoir scene, when Sarah Conner sits down, there is no Canada Dry drink in hand. Seconds later, during the same "You've got me Burning" song that is playing in the disco, the bottle is in hand.
When the Terminator gets on the motorcycle to chase after Sarah in the pick-up, he turns on the ignition key and jumps up on his right leg to kick start the bike, but you hear a electric starter motor instead before he rides off.
The rear-view mirror has been removed from the Cadillac that Reese steals.
When Sarah and the Terminator are crawling through the hydraulic press, the top of the press can be clearly be seen wobbling like plywood in the background lighting. This is the same press that is strong enough to crush the robot by the end of the scene.
When Traxler and Vukovich arm up with assault rifles during the police station massacre, an officer with a shoulder rig is seen behind them grabbing his own M16. Later, when the station is on fire, the Terminator steps over the same officer dead on the floor, armed with only his revolver.
When the Terminator examines the Spas-12 shotgun in the gun shop he pulls back the bolt and takes aim, then the camera switches to the store owner (Dick Miller) during which we hear the "click" of the Terminator dry-firing the weapon, then the camera switches back to the Terminator revealing the weapon is still cocked meaning he did not actually dry-fire the gun. The click was added later during editing.
After the lights blow out on the tanker truck while driving from the sidewalk back onto the street, they are on and working as the tanker truck explodes.
When the tanker truck runs over the Terminator and comes to a stop, the driver gets out to check on him while the passenger waits in the cab. The driver however doesn't close his door and the door fails do so on its own. After the Terminator kills the driver, he opens the door and commandeers the truck. Who closed the door? There's no reason for the passenger to have done it.
In the Tech Noir club, the Terminator passes by a woman on the dance floor wearing an orange shirt. A few shots later, when the Terminator focuses on Sarah, the same woman can be seen in the background sitting at a table and talking with friends. There wasn't enough time for her to move.
When the Terminator is done operating on his own eye, he has a robotic eye. As soon as he puts his sunglasses on, Arnolds eyes are back to normal and clearly visible through the glasses from that moment on.
In the first two car chases between Reese and the Terminator, Reese's headlights are turned off. What's more, when Kyle Reese steals the second car from the parking garage, he again doesn't turn the headlights on. When we see the car exit the parking garage, the headlights are on. But when we see the car again, the headlights are off again.
In the tunnel after ditching the car Sarah realizes that Kyle is wounded and dresses his wound, which Kyle comments on as being a pass-through wound. After spending the night in the tunnel, upon leaving, the bandage has no blood on it. Yet, later, after Kyle returns to the motel with supplies, they bandage is saturated with blood.
At the end of the movie when Sarah is at the gas station, she uses an English to Spanish dictionary to speak to the attendant. A moment later, a boy takes her photograph then speaks to her in Spanish about a storm coming. Sarah then asks the attendant what the boy said, and he translates the boys Spanish into English for her.
