Terminator 2: Judgment Day goofs

After Sarah assaults the unsettling guard at the psychiatric hospital and runs down the corridor with a truncheon, you can hear the sound of hard‑soled shoes even though Sarah is barefoot.

When John rings his "foster mother", the T-1000 answers a Slimline telephone; yet that Slimline instrument has only a single bell. The ringing heard when it is answered is actually the tone of a Western Electric 500 — a two-bell telephone. Furthermore, the ringing sound itself doesn't come from the handset but from an ageing vinyl analogue recording, showing pitch wobble consistent with the uneven surface of that particular record and with the periodic pitch variation that corresponds to one revolution of the disc.

When the Terminator seizes the man in the yellow shirt, he says "ah ah get him off of me", but his lips do not move.

When the T-1000 fires the Beretta 92FS in the shopping centre corridor, the shots sound muffled and distorted as if a silencer were fitted, despite the pistol having no silencer attached to its muzzle.

When Dyson and a security guard initially unlock the vault containing the T-800's chip and arm, the guard vocalises "3, 2, 1" but can be seen mouthing "1, 2, 3". Later, Dyson also joins John in counting "1, 2, 3".

In a chase sequence, the Terminator, riding a Harley, passes in front of a Honda CRX whose driver sounds the horn at him, but the noise heard is not that of a Honda CRX horn.

The engine noise of the motorbike John rides in the aqueduct bears little relation to his hand movements on the handlebars. John's throttle movements on the motorbike scarcely align with the acceleration, engine and intake audio tracks of the machine he is "controlling".

John says, "Right. Time out. Stop the bike." Afterwards he and the Terminator ride into an alleyway and come to a halt. Once they have stopped, the reflection of the boom microphone can be seen momentarily on the mudguard of the motorbike's front wheel.

(at around 49 minutes) Sarah tells Dr Silberman that there are 215 bones in the human body. In reality, an adult has 206 bones; humans start life with about 270 bones, many of which fuse during development to give the adult total of 206. Had Sarah completely broken his forearm, two bones would have been fractured — the radius and the ulna. Instead, she struck his wrist at the base of the thumb, so she broke his hand rather than his forearm.

A security guard at the establishment glances into his cup, which contains two jacks, two aces and a queen, and cries out "Hey, I got a full house." Two pair is not a full house.

In the biker bar, the Terminator surveys a number of patrons to find matching body shapes and clothing. The body‑type descriptions do not always correspond to the individuals he inspects.

[Special Edition] In the Special Edition, Miles Dyson powers down his computer simply by pressing the Enter key. The display doesn't show any shutdown screen that would justify such a single‑key action.

[Special Edition] As Sarah Connor is about to remove the CPU from the Terminator he says 'Do it'; take a close look at John Connor (Edward Furlong) on the left of the frame, holding a light — he looks directly at the camera.

Arnold Schwarzenegger's Terminator makes a sound transcribed as "exhales" while replacing the lorry's starter motor, as though turning a torque wrench demanded effort. At that strength, the T-800 could have rotated the wrench with only his little finger.

Despite being an unrelenting killing machine on a mission, the T-1000 doesn't always behave as if he takes it seriously. In the arcade he is shown strolling down the stairs at a leisurely pace instead of running to pursue John, and there are several other moments in which he seems to intimidate his victims rather than immediately finish them off (walking through the bars, wagging his finger, etc.).

When John starts crying, the Terminator asks him what is the matter with his eyes. A few minutes later, while stitching Sarah's wound, he states that he has "detailed files on human anatomy," which would presumably cover the tear ducts.

Even if he does not understand human emotions, he would at the very least know where John's tears are coming from and likely appreciate their function — crying, a reaction to dust and so on. He certainly would not presume there was anything "wrong" with his eyes.

To open the Cyberdyne vault from outside, both keys must be turned in unison. Dyson and the security guard do not turn them together.

It is established that the T-800 is obliged to carry out any directive John Connor gives him. Strangely, the Terminator also complies with any command Sarah issues.

Schwarzenegger's Terminator tells John that the T-1000 is made of liquid metal. In fact, the T-1000 is usually in a plastic, or at least ductile, condition rather than a true liquid. When it is shot or sliced open, it can be seen to be in a malleable state rather than flowing like a liquid. It only becomes liquid in particular instances — for example, when it melts after being frozen and shattered, or when it liquefies in the molten steel.

When Sarah meets Enrique, they both realise they can trust one another and put their weapons away. Sarah engages the safety catch on her pistol but then holsters it with the hammer cocked and a cartridge in the chamber. That is far from a fully safe condition for a firearm. She should have decocked the hammer and only then applied the safety catch before holstering the weapon.

The Cyberdyne emblem on the security guard's sleeve in the Cyberdyne Building is incorrect: it shows two black triangles and one silver triangle, whereas the proper logo features two silver triangles and a single black one.

As the T-800 approaches the pub, it scans a car and the readout displays "Plymouth Sedan", even though the vehicle is in fact a Ford.

Sarah recognises the Terminator when she sees him emerge from the lift, even though he is wearing sunglasses and Terminators can age.

In Terminator 2: Judgement Day (1991), the Terminator rides his Harley off a ledge into a ravine. In the first shot of the jump the ledge he launches from is pointed; in the following shot it's flat.

As John, Sarah and the Terminator commandeer a police car while fleeing the psychiatric hospital, the number on the number plate alters across the shots as follows: 999273 > 999232 > 999273 > 999001 > 999013 > 999018.

In the scene where the T-1000 drives the lorry off the road and into the canal while pursuing John Connor, its axle snaps on impact with the ground. In the following shot the lorry appears stable once more.

When the Terminator's arm becomes trapped in the gears, he cuts it off below the elbow to free himself and carry on fighting the T-1000. Towards the end of the battle, as the Terminator is crawling towards the grenade launcher, the damage is clearly higher, well above the elbow.

The T-1000 fires bullets into the Terminator's back, but the damage to his jacket vanishes when he is thrown through the window. Director James Cameron said the sequence had been scripted differently at the time of filming.

In the amusement arcade, John appears to be playing an expert-level game of Missile Command (1980), yet his final score is a mere 400 points.

In the psychiatric hospital the Terminator shoves a woman in the face; she slides along towards the bars and comes to rest by an opening on the right. When the T-1000 later approaches the bars slowly, that same gap on the right is visible but the woman has vanished. Then, as the T-1000 breaks into a run and opens fire, she is there again.

When the Terminator takes the lever-action shotgun away from the pub owner, the cocking lever has an oblong opening that closely fits the Terminator's hand (at around 32 minutes). Later, while firing one-handed on the motorbike, the opening of the cocking lever is noticeably larger and more rounded, allowing him to spin it and cock the gun at the same time. However, when he and John collect Sarah from the mental hospital, the cocking lever switches back to its original oblong shape.

John's watch displays times between 10:35 and 12:00 as he attempts to soothe Sarah after she almost kills Dyson.

When the Terminator is stabbed in the biker bar, it initially appears that the wound is just above the nipple (the bend in the knife is visible). In the close-up, the blade seems to pierce him directly on the nipple, but when he walks over to the biker he had thrown onto the cooker, the stab wound is several inches below the nipple.

When the T-1000 drives the lorry over the edge into the canal while continuing to pursue John, the vehicle lands on the bed of the canal and the windscreen is clearly shown falling out. However, later the windscreen appears intact — even after he passes under a low bridge that shears off the lorry's roof — and he has to push the still-intact, damaged windscreen aside because it is blocking his view.

When John instructs the T-800 to help extract Sarah, he hands it a cocked gun. However, in the shot over the T-800's shoulder the weapon is suddenly shown uncocked; in the next shot it is cocked again as the T-800 places it, muzzle pointing downwards, into his trousers — something that would be extremely dangerous were he not made of metal and lacking sensitive equipment in that area.

While Sarah is doing pull-ups on her upturned bed, her arms are slick with sweat, but when the nurses kick her to the floor every inch of her skin is bone-dry.

(at approximately 1 hour and 2 minutes) The getaway car stolen from a petrol station is broken into when its side window is smashed. Later, that window is shown intact but rolled down.

The Terminator's sunglasses are broken, but subsequently the wrong side is shown to be damaged.

In a few scenes the burn caused by the Terminator's cigar is not visible.

When the Terminator takes hold of the shotgun, it withdraws its hands from it twice.

In the steel foundry towards the end, the Terminator drives a metal bar down through the T-1000's shoulder. The T-1000 seizes the bar, then whirls and kicks the Terminator, knocking the bar free from the Terminator's right hand. In the next shot the metal bar is still lodged in the T-1000's body.

As the Terminator and John Connor ride their motorbike towards Pescadero to break Sarah Connor out, they pass the same cluster of parked school buses on two separate occasions.

The hole the T-1000 made by headbutting the helicopter's windscreen momentarily disappears and then reappears.

When the Terminator appears it's obvious the trailer has been altered: the repair patches and the warning sign on the right-hand door are gone, along with the number plate. Also, with half the tyres on the left-hand side destroyed, the trailer should be leaning at least slightly.

While the Terminator is reversing the police car, Sarah opens fire on the T-1000 and initially discharges 13 rounds, which exceeds her pistol's capacity. In every subsequent exchange during that sequence she fires only eight rounds before needing to reload.

(at approximately 27 minutes) During the getaway through the shopping centre staircases, John runs past the exit to the second floor twice, moving from the upper level down to the lower.

During the corridor shoot-out at Pescadero, Dr Silberman can be seen in the background as the T-1000 forces open the lift doors, but when the T-800 blasts the T-1000's head open, Dr Silberman has vanished.

Although the Cyberdyne laboratory is not on the lowest level of the Cyberdyne building, when Dyson, John, Sarah and the T-800 emerge from the lift there is only an "up" button adjacent to the door.

The photograph John's foster mum gives the T-1000 to identify him depicts a much younger child version of Edward Furlong. This is apparent, for example, when the T-1000 asks the two girls if they have seen John. Moreover, the T-1000 would not have been able to recognise him in the arcade on the basis of that image, since it is not a recent photograph.

During the pursuit the bridge is blown up, yet in the subsequent shot it appears undamaged, looming above the blaze.

When the Terminator smashes the driver's side window of the estate car, some shards of glass remain lodged in the window frame; in the next shot the glass is gone. (A similar scene appears in The Terminator (1984).)

As Sarah etches "No Fate" into the desk, the knife's point first tilts towards her; in the next shot it faces away, and when John lifts it from the desk the tip is once more turned towards him.

When the tanker lorry overturns in the foundry, one of the workers sets off the alarm. Logically, the alarm would continue to sound for at least several minutes, if not indefinitely, but it is never heard again after that brief shot of only a few seconds, even though the sequence in the foundry continues for at least another ten minutes.

In the motorway chase scene between the Terminator in the SWAT van and the T-1000 in the helicopter, the bullet holes in the rear door where Sarah is seated change size and position between cuts.

After John and Tim steal cash from the cashpoint, John says "come on" and darts off without completing the transaction or retrieving the magnetic stripe card that's still in the machine. In the next shot, John and Tim are running alongside one another with the computer neatly wound in its cable and the card tucked in, which he later uses again at the Cyberdyne building to obtain the vault key.

When Sarah intends to kill Dyson with her pistol, he is leaning on a marble table with several magazines on it, and their positions keep changing.

Before Sarah and the T-1000 start shooting at one another during the SWAT truck/police helicopter pursuit, the two vehicles are shown passing a car that loses control and crashes. Later on in the chase (before they go past the tanker lorry) the very same car is seen again, once more spinning out of control and crashing.

Before the Terminator rides his motorbike into the canal, he gets through a set of gates by shooting the padlock off first. The second time he fires at a gate, the edit instantly shows him going from holding a shotgun in his left hand to having both hands on the handlebars.

In the original film, both Kyle Reese and Sarah Connor have blue eyes. As John Connor is their son, he would be expected to have blue eyes as well. He could, of course, be one of the very few people whose eye colour changes from blue to brown with age. Yet when Sarah asks Kyle to describe her son in the future, he specifically says that John has his mother's eyes — blue. However, in the film his eyes are clearly brown, both as a child and as an adult.

Before the time-travel orb and the Terminator appear, electrical discharges strike two lorries. The lorry on the right is larger than the one on the left. When the Terminator is outside the biker bar The Corral, the two lorries can be seen in the distance across the road; they now appear to be the same size.

In the sequence where the Terminator dives into the canal on his motorbike and overtakes the lorry to rescue John, who is on his own motorbike, successive shots a fraction of a second apart show the canal appearing fully sunlit, entirely in shadow, and half in shadow and half sunlit.

In the mental institution, John, Sarah and the Terminator dash into the lift as the T-1000 opens fire; at least two rounds punch holes in the back of the lift just above the white stripe. Yet in many of the following shots the rear wall of the lift is shown unblemished — for example, when the T-1000 drops down into the lift, nearly the whole back panel appears intact with no holes.

In the sequence set in the steelworks, after the T-1000 stabs Sarah Connor in her right shoulder and lifts his right hand to form a metallic point aimed at the space between her eyes, the film cuts to a close-up of the T-1000 as he tilts his head into a menacing expression. In that shot his right arm — which should be raised to make the spike — is not raised at all. When it cuts back to another close-up of the T-1000, his right arm is once again elevated to form the metallic point.

At approximately 1 hour 40 minutes into the film, in the scene at the Cyberdyne building, the front mudguard of the police motorbike is clearly alight. Subsequent shots show the mudguard to be in immaculate condition.

In the mental institution's car park, the Harley-Davidson motorcycle reverses five feet immediately after the T-1000 begins pursuing the Terminator, Sarah and John.

The T-1000 leaps from a window on the storey that was just blown apart to reach the helicopter, yet he crashes through an intact window, despite it being evident the blast had shattered every window on that storey.

As the Terminator steps out of the lift to confront the SWAT team at the Cyberdyne building, his grenade belt is in a different position.

While the Terminator is in the pub and asks the biker for his clothes, boots and bike, you can clearly spot a member of staff in the kitchen. Before another man tries to help the biker the staff member is still visible, but when the cue is broken across the Terminator's neck and the kitchen is shown again, there is no trace of the worker and there is no way he could have left in half a second.

While Sarah is getting ready to flee Pescadero Psychiatric Hospital, she ties her hair into a ponytail but a large section remains hanging loose. In the following shot, all of her hair is neatly secured within the ponytail.

The T-1000 slams a rolling girder into the Terminator's head, the girder visibly scraping his flesh; yet when he withdraws it there is no flesh or blood left on the metal.

When the Terminator fires at the T-1000 just before dashing for the lift to flee the facility, Dr Silberman is visible standing immediately beside the T-1000. In the subsequent cut the T-1000 pursues them while firing back, but is now depicted running past Dr Silberman once again.

When the T-800 crushes the Cigar Biker's hand, the biker behind it strikes him with a cue, snapping it over his head. However, as the T-800 approaches the Cigar Biker, the other biker is already holding the cue the wrong way up.

While they're travelling in the battered estate car, during the sequence in which John teaches the Terminator to adopt more informal speech (for example, not saying "Affirmative"), John's right arm alternately rests on and lifts from his raised knee between the point-of-view cuts.

When the Terminator shoots the T-1000 down in the shopping centre corridor, the T-1000 is seen looking straight at the Terminator with his mouth closed. However, in the next shot he is seen looking up at the ceiling with his mouth open.

In most foreign-language dubbed releases, when John Connor (Edward Furlong) is seized by The Terminator and the Terminator takes bullets in the back from the T-1000 while shielding John, the scream you hear is actually John's — voiced by Edward Furlong — rather than the voice of the local dubbing artist. A probable explanation is that a wordless scream tends to sound much the same across languages.

John's motorbike shifts position as it is run over by the lorry driven by the T-1000.

After Sarah breaks Dr Silberman's arm, two consecutive shots are inconsistent: as she reaches for the Liquid Rooter bottle, it appears to move on its own before she touches it. The bottle turns so the Liquid Rooter logo faces the camera, whereas previously that logo had been more to the left and partly out of view. Also the black pole Sarah is leaning on, which had been beside the cleaning trolley wheel, shifts further to the right between the cuts.

As John cycles to the Galleria, his friend Tim, riding on the back, is holding the stereo on the right-hand side of the bicycle, which a second later appears on the left-hand side. It must remain continuous, as the song ("You Could Be Mine" by Guns N' Roses) playing is uninterrupted.

During the canal chase, just before the lorry loses its roof, it runs over a shopping trolley. When John passes the trolley it is lying on its back with the wheels pointing to one side, but in the shot of the lorry hitting it the trolley is in a different position — upside down with the wheels facing upwards.

After escaping from the psychiatric hospital, John throws a small fragment of the T-1000 from the police car; it comes to rest beside the central yellow line and a cat's eye in the middle of the road. When the T-1000 moves over to reabsorb the fragment, it finds the piece in a different spot and the yellow line and cat's eye are no longer visible.

In the biker bar scene, when the Terminator stabs the biker in the shoulder, the layout of the balls on the pool table the biker is leaning on differs between shots. While the Terminator is twisting the biker's arm, three stationary dark‑coloured balls sit near the pocket behind them. When the camera cuts back up after the stabbing, that same pocket shows light‑coloured yellow and orange balls close to it, also motionless. Although the biker contacts some balls with his arm, those balls remain stationary and do not look as if they have been set in motion by the contact.

After the T-1000 boards the helicopter and the original pilot jumps out, the helicopter's door appears to shut behind him; yet the T-1000 then reaches across to close a door that is still visibly open.

As the camera cuts, the T-1000 thrusts the metal pole through the Terminator twice and is then standing in a different position.

After the shopping centre, while the T-1000 is pursuing John in a lorry, it collides with two cars crossing its path, sustaining some damage to the lorry's grille, headlamp and bumper, yet the shot of the lorry approaching the bridge, just before it drops into the canal, shows it has no visible damage before striking the bridge.

As they make their getaway from Cyberdyne, the SWAT truck's rear door on the left (right) side is ajar.

Blood stained the floor during Sarah's escape from the hospital.

During the motorway chase, when the Terminator flips the SWAT van, its left windscreen comes out entirely. However, later as they walk over to the smaller van and the Terminator says "We need your truck", the SWAT van's left windscreen can still be seen in place.

(at around 57 minutes) The police car's siren lights, which had been stolen by The Terminator, Sarah and John in the mental institution's car park, changed from all-blue to orange-and-blue.

When the SWAT truck ploughs into the foyer, it knocks off a wing mirror, which is later seen again.

Whilst the T‑800 returns fire at the T‑1000 with his shotgun, none of the rounds actually strike his body, even though the T‑1000 is firing rapidly at him and the opening shots are shown making contact.

While the T-1000 is driving the Nitrogen lorry down the motorway pursuing the Terminator and the others in their stolen van, the lorry passes a car, yet in the subsequent shot the lorry is shown behind the van and the previously passed car is nowhere to be seen.

Rounds remaining in the tear-gas gun as the Terminator steps outside.

In Sarah's dream of a nuclear blast, only the figures in the foreground are depicted beginning to smoulder immediately after the detonation.

When the genuine Sarah Connor steps out from behind the T-1000, who is disguised as her, she tells John to move aside so she can shoot the T-1000. In the moments that follow John looks down and sees the T-1000's feet merging with the steel floor, realises which figure is actually Sarah, yells, "Shoot!" and steps away — all before Sarah finally fires. Oddly, by the time she does fire the T-1000 is still "playing" Sarah — feigning injury, remaining in disguise — even though Sarah is plainly about to shoot him and John has already worked out it is him and moved out of the way.

On two occasions the hail of bullets seems to stop striking the Terminator for a brief moment, even though he's shown being swept by gunfire. The first instance is when he's being shot at just as he is about to return fire on the T-1000 in the shopping centre corridor. The second takes place when roughly a dozen SWAT officers unleash a barrage on him with no apparent effect as he pulls out his pistol and begins shooting at them.

During the canal chase, when John stops and looks back, the bridge behind him bears a sign reading "Hayverhurst Avenue", but when the shot cuts to the lorry crashing through the wall the street sign reads "Plummer".

The exact spot where the Terminator lays the pistol on the ground.

In the scene at Miles Bennett-Dyson's home, when he is lying on the floor beside a coffee table after Sarah Connor has shot him, the magazines on the table show different titles and are arranged differently.

As John and the T-800 arrive at the hospital gates, the T-800 shoots a guard in the leg, sending blood spattering against the wall of his post. When the T-800 returns to John, the blood has vanished.

The lorry that is damaged as a result of the Terminator's time jump is a completely different vehicle to the one shown just before the burst of light from the jump fills the frame. When you compare the two lorries, before and after the flash, the original has a sticker and several markings on the rear that either vanish or change between shots, and the number plate disappears. The camera's position also seems to shift by a few inches.

The man couldn't possibly identify John Connor in the photograph at the very moment the T-1000 questions him, just after John peers over Tim's shoulder.

The Pescadero lift's doors open at the last moment to save the trio from the advancing T-1000, despite nobody having pushed the lift button — earlier on Sarah had shown that the doors only opened when they were pushed.

Just before Connor first encounters the Terminator in the corridor of the shopping centre while fleeing, he goes through two double doors that are usually kept closed. He then turns to his right and spots the Terminator; when he turns back the double doors he had just opened and run through (despite the doors being shown closing after he passed) are propped open, so he doesn't have to open them again.

During her escape from the psychiatric hospital Sarah breaks Dr Silberman’s arm and then helps him hold it upright to ease the intense pain. Yet, only minutes later, when Sarah is apprehended by the orderlies just before both Terminators and John arrive, Dr Silberman’s arm is merely hanging by his side with no sling or other support. While the shock of seeing the Terminators might account for the final instant of that scene, it does not explain the earlier moment before the Terminators appear.

When the Terminator blows up the second of the pair of police cars at Cyberdyne, there is a cut between the grenade striking the car's window and the actual explosion. This becomes apparent if you focus on the grenade launcher and the three police officers running out of frame as the projectile hits the window: the launcher seems to drop several inches in the space of a millisecond, almost like stop-motion, and the officers vanish abruptly.

When the pub owner fires the shotgun, its report is noticeably quicker and more subdued than at any other moment it is discharged; once the T-800 takes it from him, the noise shifts from a loud hiss to a cannon-like boom.

The dimensions of the wall that the lorry's cab crashes through vary.

When John is explaining to the T-800 that he cannot kill people (as John puts it "you just can't"), a parked car with some frosting or misting on the front windscreen is visible in one shot behind them, and you briefly see the driver's window rolled up. Later, after he discovers the Terminator can follow basic commands (for example, standing on one foot), and when an athlete is grabbed as he tries to help John, the same car — its front windscreen still showing some frost — is seen with the driver's window rolled down, open or out of view in subsequent shots, and with damage on the other side.

When the Terminator drives the estate car out of the garage at the petrol station with John in the front passenger seat, the front passenger window is closed. They immediately pull up to collect Sarah, and that window is rolled down.

The T-1000 instructs the helicopter pilot to leave the cockpit, and he does so, tumbling several dozen feet to the ground. The very next shot shows the ground beneath the helicopter, yet the pilot is nowhere to be seen.

A camera enclosed in a protective box is visible on the side of the lorry.

Camera lights are reflected in the glass in the shot behind Dyson while Sarah Connor aims her laser sight at him.

At Cyberdyne, the SWAT team leader says, 'OK, drop him,' and they open fire. In the background on the left-hand side of the screen, a crew member wearing a white T-shirt walks into the frame and exits to the left. (Widescreen DVD)

As the Terminator hoists John Connor from the off‑road motorcycle during the canal pursuit, the stunt driver for the recovery vehicle can be seen.

(at about 1 hr 40 mins) The camera and the lower halves of the crew are reflected in the T-1000's sunglasses as it moves through the flames in front of Cyberdyne.

As the T-1000 ploughs the lorry into the bridge, a dummy is plainly visible in the driver's seat.

A camera and a large stage lamp are reflected just above the recovery lorry's grille as the camera tilts up to reveal the T-1000 through the battered windscreen.

(at around 29 mins) When the T-1000 is driving the lorry pursuing John along a street, it ploughs through two cars stuck in traffic. A brief shot from a camera mounted on the side of the lorry shows it approaching them. Looking down the road, beyond the two cars, you can see a special lorry with an open rear directly in front of the vehicle the T-1000 is driving, with a camera and four crew members standing on its rear.

The camera's shadow can be seen as the grille shuts over the Terminator following the opening credits.

When the Terminator is reversing the police car in the underground car park to get away from the T-1000, just as he says "Hang on" before being flung backwards onto the pavement, you can briefly see the actual driver steering from the centre of the rear seat, looking out of the rear window (visible for a few more frames afterwards), and then he disappears when the T-1000 climbs onto the boot and smashes the rear window.

When the police enter the Cyberdyne building, a cameraman's reflection is briefly visible in one of the foyer's windows.

Prior to the grenade launcher being discharged at the police vehicle parked outside the Cyberdyne building, the explosive device affixed to the vehicle at the spot where the grenade will "strike" can be seen.

Moments before the T-800 shoots out the lorry's tyre, a thick red rope or cable can be seen attached to the rear of the motorbike's seat, extending upwards and disappearing off the right-hand side of the frame.

Upon the Terminator's arrival from the future, as he walks towards the pub, the camera is briefly seen reflected in the small window of the door before he opens it.

The eyelets on the rear-projection screen are visible on the left-hand side of the image during the opening future sequence, at 2 minutes and 40 seconds into the 4K edition.

During the sequence in which the T-1000 rams the lorry into the bridge, the collision is shown from two perspectives — one from a ledge above and one at ground level. When it cuts to the ground-level shot, a camera operator is briefly visible over the ledge in the upper-right corner, filming the higher-angle view of the crash.

At Cyberdyne, after two warnings were given to the T-800 to surrender, the SWAT team begin firing at their worst nightmare. The T-800 continues to stride toward the ten SWAT members who have taken tactical positions around the desk. Directly above a crouched SWAT member on the right sits a weapons crewman, wearing white protective earmuffs, red-striped trousers and a white shirt with a jumper.

At the bar, while Arnold is searching for clothes, he hurls a man onto the kitchen grill. As the man falls to the floor, the nozzle that produces the smoke can be seen beside his left hand.

When John is escaping along the canal, he is clearly travelling upstream. He follows a narrowing, convergent branch and the canal becomes smaller. However, when the T-800 launches the motorbike into the water, he does so from a spot that would split the fast-moving current rather than bring it together, so inexplicably they end up going downstream. A flood-control system never diverts water outward; it channels it into progressively larger waterways towards a single outlet.

During the pursuit, shots of the canals and flyovers are shown out of sequence.

When the Terminator uses the M79 "Thumper" grenade launcher to blow open a door at Cyberdyne, he is standing only about 10 ft from the door and it bursts open spectacularly. This is inaccurate, because 40mm HE (high-explosive) rounds fired from that weapon do not arm until they have travelled roughly 30 metres (approximately 90 ft). At such close range the round would have at best dented the door or produced a hole about 40 mm in diameter, depending on the material of the door.

Dyson must pass through what is described as a "cleanroom" to reach the storage area for the chip and the robotic arm. Cleanrooms are not intended to be used as access routes; no one would be permitted to enter without appropriate protective clothing, such as the two operatives are wearing. They are designed either to protect staff from hazardous substances or to prevent contamination of whatever is being worked on. Thus "civilians" would not simply be allowed to walk through.

Dan Stanton is listed in the film's credits as "Lewis as T-1000". That is wrong; it should read "T-1000 as Lewis", because the T-1000 is impersonating Lewis, not the other way round.

The SWAT team stormed into the room at Cyberdyne and opened fire without hesitation. Such a tactic would have been unlawful, since they could not have known that John Connor and Miles Dyson were being held hostage by the Terminator and Sarah Connor. The team also ended up shooting and killing Miles Dyson, who wasn't holding any visible weapons and wasn't posing a threat to anyone.

When John first flees up the canal on his motorbike, he shifts through gears far more often than the machine would realistically need. Each time the camera cuts back to him he selects another gear and immediately revs it hard while still accelerating, never easing off enough to warrant changing gear.

The Terminator would be regarded as an android rather than a cyborg. A cyborg is a living organism augmented with technology, while an android is a machine built to resemble a human.

The bulletproof vests that Sarah stuffed into the van's windows would not have stopped the rounds simply by being loosely jammed there; the impact of the gunfire would have forced them back out of the openings. They would have needed to be firmly fixed into the window frames to provide effective protection.

In the scene where the T-1000 is slowly riding a Harley-Davidson through the burning building, his left hand is on the handlebars while his right hand holds a pistol — which shouldn't be possible because the throttle is on the right-hand side, yet the Harley continues moving forwards.

When the T-800 first appears in the sphere, the sphere shears off the left rear corner of a trailer. It also cuts the rear set of tyres and rims in half, yet the trailer doesn't settle at all despite its four rearmost tyres being instantly deflated.

Whilst escaping Cyberdyne, Sarah and John are sharing a single gas mask. Even if that might have allowed one of them to carry on (unlikely, especially since each swap would pass the trapped tear gas to the next wearer), in their final dash John is the one wearing it, yet Sarah is using her eyes to guide them both to safety through the clouds of tear gas. At best, she would have had to keep it on herself and make him close his eyes and hold his breath.

In the opening scene, set in the future, human combatants are battling Terminators; a resistance fighter is shooting at a partly disabled Terminator lying on the ground at point-blank range. Smoke and spent cartridge cases can be seen ejecting from what appears to be the energy weapon he is firing.

At Pescadero the Terminator shoots the gate guard and remarks that he'll survive; however, with numerous veins and arteries running parallel and behind the knees, firing at that angle would almost certainly have struck an artery. The guard would have bled out from blood loss almost immediately.

The detonator utilised at Cyberdyne to destroy the labs was a black, high-tech electrical box with a claymore clacker (detonator) fastened to its top. The clacker has a black plug on the end that needs to be opened so the blasting caps can be attached, or in this case so the black box can be connected by electrical wiring. In several shots it is plainly visible that there are no wires attached to it and that the plug is firmly closed.

When the T-1000 crashes the recovery lorry beneath the bridge, a spark from the battery cable appears to ignite the escaping diesel, triggering a massive explosion. This wouldn't happen in real life — a spark alone would not set diesel fuel alight.

Sarah's opening narration contains a significant inaccuracy. When she says "it was just a question of which one would reach him (John) first," referring to the T-1000 and the T-800, that is plainly incorrect: although the T-800 reaches John first, the threat to John's life continues throughout the remaining two-hour running time of the film and, indeed, constitutes the central narrative.

Blood is red, but when it seeps into clothes it dries to a brown colour; yet the blood on the rear shoulder of Sarah's white tee-shirt remains red even after several hours that should have allowed it to dry and brown.

(at around 1h 40 mins) When the T-1000 is in the helicopter pursuing Sarah, John and the T-800, he reloads his firearm. He uses both hands to reload, while a third hand is clearly visible controlling the helicopter's joystick — as if he has grown an extra arm to fly. In fact, four arms are visible in the scene, each of which the camera clearly focuses on.

(at approximately 1 hour 12 minutes) Dogs typically bark loudly when a Terminator is nearby; yet at Enrique's ranch the animals are seen playing despite the Terminator being close. In the first film Reese merely states that the Resistance used dogs "to spot Terminators." He does not claim that every dog will bark at every Terminator. Dogs are individuals; one might raise the alarm at an intruder while another might remain quiet.

In the original film we are told only living tissue, or objects encapsulated in living tissue, can pass through the time portal, yet the T-1000 is made of liquid metal. Exactly how the T-1000 travelled back is never explained, so the mimetic poly-alloy appears to be an exception to that living-tissue rule for time travel. And why the T-1000 adopts the form of a naked man when it is entirely metallic remains another unanswered question.

When the T-1000 arrives from the future and hijacks a police car, he accesses John Connor's details on the police computer, including his home address. Yet inexplicably, the T-1000 does not turn up there until the following day, after the T-800 had already come and gone. It may simply be that the T-1000 was further from Connor's home than the T-800, the future John Connor knowing where he used to live and ensuring the T-800 materialised nearby.

(at about 1 hour 15 minutes) On the playground, as Sarah desperately tries to warn people, the shock wave obliterates everything (even burning flesh down to the bone), yet the little spring-mounted rocking horse in the background does not move at all. Since this is a dream sequence, it need not obey the laws of nature.

(at around 47 minutes) The T-1000 is not meant to be able to turn itself into objects with moving parts. Yet when it kills and replaces the hospital security guard, it briefly appears to have many moving elements before taking the guard's gun — a keyring full of keys, a name badge with a clip, etc. However, those items are merely mimicked by the T-1000 and are not actually complex objects with working moving parts.

(at around 46 minutes) The Terminator explains to a young John Connor that the T-1000 can mimic anything it touches. When it imitates the guard in the institution, the only part it actually contacts are the soles of the guard's shoes, as it was concealed as a section of the floor. However, touching any portion of an object enables the T-1000 to scan the whole object and reproduce it. The shoes are not separate items but the lower part of the guard object. The T-1000 perceives the guard as a single object (like a toy action figure with its clothes and shoes textured and coloured onto it). The T-1000 does not have to touch the guard's flesh to be touching the guard. It is not separately mimicking shoes, socks, shirt, trousers, underwear, feet with all five toes, skin under the clothes, and so on. It is simply creating an action-figure-like replica with clothing and shoes rendered as part of the guard object — only the outward appearance of the guard. But this still does not explain how the eyes, hair, keys, uniform, & body shape are replicated, unless the process relies on optical scanning of the subject, which would make tactile sampling unnecessary and thus a plot hole.

(at around 20 minutes) Sarah Connor tells the doctor she has been well-behaved for six months, and he agrees. Shortly beforehand he had told the pupils that Sarah had stabbed him in the leg with a pen only three weeks earlier. However, he might simply have agreed to avoid confrontation, or he may have exaggerated the incident when speaking to the class.

(at around 1 hour 30 minutes) When the Terminator fires the minigun at police cars inside the Cyberdyne building, the ammunition belt doesn't feed into the weapon. On this model, manufactured by General Electric, what appears to be a belt is in fact an enclosed feeder.

(at around 1h 55 mins) In the steelworks, the T-1000 asks Sarah to phone John even though it could quite easily clamp her mouth shut and mimic Sarah's voice. However, earlier in the film (at around 36 mins) the T-1000 attempted to impersonate John's foster mother and John saw through the disguise, so the T-1000 prefers to use the genuine article rather than risk an imperfect imitation. A deleted scene also explains that the T-1000's mimicking abilities were hampered by exposure to nitrogen.

(at around 6 mins) Outside the biker bar, as the Terminator scans the motorbikes and then the car, the screen registers the vehicle as a Plymouth, when in fact it is a mid-1980s Ford LTD Crown Victoria. However, in the first film Reese mentions that most records were lost before or during the war, so the Terminator might not hold a completely accurate record of pre-war vehicles.

(at around 1h 35 mins) Miles tells the SWAT team he can't hold the detonator much longer; rather than evacuate, one of them could have simply taken the detonator from him while the others summoned the bomb squad to dismantle and render the device safe. However, it is likely they assumed he would intentionally detonate it if they tried.

(around the 2-hour mark) At one point the Terminator remarks that he needs a holiday; Terminators wouldn't normally be programmed with that sort of sarcastic humour. However, it could be interpreted as a sign that he is learning to imitate human behaviour.

(at around 1h 2 mins) The colour of the Terminator's T-shirt shifts from black to a pale blue/grey overnight while he stands guard in the abandoned petrol station. However, the bullet holes also vanish, which suggests it's a different shirt, probably one from the garage.

(at around 2h) The filmmakers took considerable steps to make clear that both Terminators are, at their core, machines. For example, Robert Patrick underwent extensive preparation prior to filming so he could run expressionless, showing no hint of fatigue while pursuing John Connor.

Yet in its final confrontation with Sarah Connor the T-1000 behaves exactly as a human would: it gestures with its finger and slowly shakes its head in a deliberately cruel manner. (Not as a necessity to blend in — they were alone in that scene.)

While one might regard this as an instance of artistic licence for that particular moment, it remains atypical for a machine to display such overtly human behaviour.

However, the T-800 is depicted as having learned and adopted human behaviour by this stage of the film, so it is reasonable to infer that the far more advanced T-1000 may have done likewise.

(at around 6 mins) In The Terminator (1984), when the Terminator arrives through the time port his hair matches the "moulding" used for all Terminators. However, in T2 when he emerges from the time "bubble" his hair looks the same as it does after the car crash scene in the first film when he puts on the sunglasses. John may have altered his appearance to make him more acceptable to Sarah. It is also possible that Skynet customises each Terminator before deploying them so that, at least from a distance, they appear different from one another.

(at around 1 hour 45 minutes) [Extreme Edition only] When the T-1000 calls at the Dyson residence, he hears on the police radio the control room ordering all available units to attend the Cyberdyne Building, giving the address as "2144 Kramer Street". In a later scene, as police units are en route to the Cyberdyne Building, one officer asks the control room to repeat the address; this time it is given as "2111 Kramer Street". Because the company's campus is extensive, there may be several buildings with addresses on that street close enough for a responding officer to locate the active site.

There are several moments in the film when John Connor gives commands to the T-800 — for instance, asking it to stop by his house (a request the T-800 refuses). He then tells it (referring to his mother) that it has to get her out of there (again denied by the T-800). John then says "We have to go right now", which is once more refused. He then says "Let me go", and the T-800 complies. When John asks "Why did you do that?" the T-800 replies "because you told me to." If so, it should have followed John’s earlier orders, but those prior instructions would have put John at risk and the T-800’s primary objective is to keep John safe from the T-1000.

(at about 1 hr 19 mins) When Sarah fires her first shot at Dyson, the computer screen is struck in a different spot to the laser-sight dot; however, given the silencer and the likelihood she hasn't calibrated it precisely, the impact isn't far off.

(at approximately 1 hour 40 minutes) Bullet holes can be seen in the roof of the SWAT van when it crashes; these were caused during the earlier confrontation with the Terminator, not the subsequent encounter between Sarah and the T-1000, which was limited to the rear of the vehicle.

(at around 1h 9 mins) When the Terminator first picks up the Minigun, he smiles at John — an emotion he normally does not possess. However, it might be interpreted as evidence that he is learning to mimic human behaviour.

(at about the six-minute mark) While the Terminator scans the motorcycles before entering the pub, the penultimate bike is labelled "Harley-Davidson Electroglide" instead of the correct "Electra Glide". However, Reese states in the first film that most records from before the war were lost or destroyed during the conflict, so it is reasonable to assume a Terminator would not have an entirely accurate database of pre-war vehicles.

(at around 12 mins) When the foster mum Janelle Voight asks her husband Todd to help get John to tidy his room, Todd drops his cigarette into the room's ashtray before heading out to the garage to confront John. Moments later, as John rides off on his bike, Todd is outside holding a half-smoked cigarette, which he then drops onto the ground. If you watch Todd's hand just before he goes outside, he actually flicks ash from the cigarette into the ashtray with his thumb and stands up with the cigarette still held between his fingers.

(at around 27 minutes) In the shoot-out at the Galeria the T-1000, disguised as a policeman, is shot but promptly repairs itself. The fabric, however, ought not to have mended, since clothing is not part of the cyborg's structure. Yet the film repeatedly shows that when the T-1000 alters its appearance its clothing changes with it, implying the garments are merely a simulated covering.

(at around 29 mins) When the T-1000 forces the lorry into the canal, a lamppost in the background displays a sign saying "Plummer Ave", while the concrete bridge is marked "Havenhurst Ave". This isn’t a mistake because Hayvenhurst, the actual name used in the film, does intersect with Plummer — the signage is therefore correct.

(at around 6 mins) When both Terminators materialise from the future, the time displacement device appears to form a spherical field with searing, red-hot rims. That wouldn't affect the T-1000, but when the T-800 arrives he is pictured on his hands and knees in a glowing ring of liquefied tarmac. Given that he is covered in human skin, you would expect his hands, feet and knees to be burned, yet they do not. Nevertheless, we never get a close-up of those areas, so it remains possible they were scorched.

John tells the T-800 that his dog's name is Max, yet the Terminator calls the dog "Wolfie" while speaking on the telephone to John's foster parents. The T-800 deliberately uses the wrong name, assuming the actual foster parents would know the dog's proper name. The fact that John's foster mother does not correct him convinces the Terminator that he is, in fact, speaking to the T-1000.

(at about the two-hour mark) In the final showdown with the T-1000, Sarah is shown using a Franchi SPAS-12 and manually chambering a fresh round, firing repeatedly — yet because the SPAS-12 can operate as a semi-automatic she would not have needed to manually "pump" it. The SPAS-12 is actually a dual-mode shotgun that can be configured for either semi-automatic or pump-action operation.

You must not look directly at molten metal. Like staring at the sun, it is far too bright, and without the correct eye protection you can damage your eyesight. Apart from the T-800 and the T-1000, the other characters are not shown looking straight at the molten steel for longer than a few seconds.

(at around 57 mins) Sarah shoots (and hits) the T-1000 seven times with a shotgun. The T-1000 displays five damage points, and only one of the two missing ones is accounted for by its morphing from Sarah's form into the police officer shape. The six shot placements after that morphing are: 1) chest (right side), 2) chest (centre/left, 'heart'), 3) 'stomach', 4) right shoulder (this hit is only seen after the next round), 5) upper right shoulder, 6) left shoulder. Possible explanation: the first hit has already fully closed up off-screen while Sarah is still firing.

(at around 1 hour 40 minutes) When the Terminator takes out the SWAT team in the Cyberdyne lobby, he first uses a handgun before grabbing a smoke-grenade launcher. After firing the handgun he drops it on the floor. Later, at the smelting plant, he employs a similar handgun against the T-1000 — a weapon that might have been picked up outside Cyberdyne from one of the many wounded officers, from overturned cars, or from inside the armoury van.

When the T-1000 accesses the police computer at the beginning of the film, it shows John Connor was born on 28 February 1985 and is listed as ten years old, which places the story between 28 February 1995 and 27 February 1996. However, the Terminator states that Judgement Day will occur on 29 August 1997 and repeatedly refers to it as being three years away. Given the specific date of 29 August, that "three years" remark would actually place Judgement Day in the summer of 1998, not 1997.

In the first film, because there were multiple women called Sarah Connor in the city, the Terminator had to eliminate each of them. In the sequel, the T-1000 entered John Connor's name into the police car's computer and it produced only a single match. Given how common the forename "John" and the surname "Connor" are, there ought to have been more than one result.

It is hard to believe that three wanted fugitives — who had seized and wrecked a building and several police cars, fired upon and wounded numerous officers, and were suspected of perpetrating a massacre of police at a station years earlier — would leave the Cyberdyne site without police reinforcements in pursuit. This becomes even more unlikely given that the emergency evacuation of the steelworks would have been an obvious tip-off to the authorities about their whereabouts.

The T-1000 often moves about in human guise and struggles to overtake its quarry. Although it can transform into far more efficient, faster configurations — for example, a wheel — it never adopts such forms.

The liquid-nitrogen lorry skids along the carriageway for much longer than its momentum could plausibly allow.

The way the recovery vehicle explodes makes it completely impossible for a single burning tyre to be ejected from the blaze after a brief pause and then roll away while remaining perfectly upright.

T-1000's pistol often fires with the muted report of a silencer, despite no silencer being fitted to the barrel.

The trio are inside the steelworks, having left a trail of destruction leading there, and remain for an inordinate length of time without any police or armed response units turning up in pursuit.

When John tells the Terminator, "Now I'm going to go get my mum, and I order you to help me" — after the Terminator nearly kills the two men trying to help him — John returns the firearm to the Terminator. He is holding it by the barrel with his bare hand, which would have been far too hot, having only just been fired.

When the T-1000 portion is hurled from the car, it breaks into a large piece centre-frame and a much smaller piece to the right. The T-1000 appears to reabsorb only the larger fragment, leaving a small remnant of itself at the roadside.

When the skeleton is shown gripping the fence, the ring and wire fixings between the bones at the base of the wrist are plainly visible. The prop was a commercially available plastic skeleton; depending on its quality, it can cost anywhere from $250 to in excess of $2,000.

It is inconsistent that the Terminator argues with John and asks why he can't "just go around killing people," when in an earlier scene he already demonstrates sufficient knowledge to conceal his shotgun in the rose box whilst he's out in public.

It makes no sense for a mass of metal to be sentient, assume human form or even speak, and it is even less plausible that separate pools could rejoin after being frozen, riddled with bullets and then melted.

When the Terminator first handles the mini grenade launcher, it is unloaded and emits a 'plonk' sound when the barrel is snapped shut — the noise an empty tube would make. In all subsequent appearances the weapon has been reloaded, and it should not have been able to produce the same 'plonk' because the tube is no longer empty. The sound is heard both when snapping the barrel open and when closing it; a round (live or spent) in the barrel would prevent the 'plonk' sound.

When the T-1000 and the T-800 are fighting in the steelworks and the T-800's arm is forced into a huge cogwheel, silvery metallic paint can be seen on his glove where the T-1000 pushed it; after the camera cuts away and then returns to the arm, the paint has vanished.

In most foreign-language dubbed versions, when Tim (Danny Cooksey) is on the motorbike with John and they leave John's home, the laugh heard remains Danny Cooksey's original — the dubbing performers did not re-record it.

Two shots show the T-800 employing an M79 "Thumper" grenade launcher to blast through doors at the Cyberdyne plant. Given that terminators possess superhuman strength, it seems more plausible that he could simply force the doors open physically rather than waste valuable ammunition.

At the hospital, as they run to the lift, the T-1000 empties his entire magazine into the T-800's back, despite already having learned during their first encounter at the shopping centre that such gunfire does not harm him.

There is no plausible reason why the T-800 would possess "detailed files" on Miles Bennett Dyson, nor any reason why he would know "what he looks like and where he lives".

In the director's cut, John seeks out someone who is smiling so he can demonstrate to the T-800 what a smile looks like, rather than merely smiling himself.

At the steel mill the T-800 insists that John must leave straight away when the T-1000 is closing in on them. At the hospital he does likewise after the T-1000 walks through the bars. But at the shopping centre, when the T-1000 is temporarily "knocked out", the T-800 doesn't tell John to leave, as if he had momentarily forgotten his mission.

After the T-1000's lorry explodes, the T-800 brings his motorbike to a halt, glances back for a few seconds and then carries on riding. There is no reason for him to stop his bike in that situation.

Todd and Janelle show no sign of alarm or curiosity when a police officer and a large, menacing man on a Harley call at their home to ask about their foster son, even though neither of them offers any explanation for their visit.

When the genuine Sarah Connor appears behind the T-1000 while it is disguised as her, she tells John to move out of the way so she can shoot the T-1000. In the seconds that follow, John looks down and sees the T-1000's feet merging with the steel flooring, realises which figure is the real Sarah, yells "Shoot!" and steps aside — all before Sarah finally does shoot. The T-1000 therefore has plenty of time to finish John off, who is only a few feet in front of it, yet oddly does not, remaining ""in character"" even though a threat has approached from behind and exposed him.

Tim, a friend of John's, tells the T-1000 that he does not know John (the photograph shows a very young Edward Furlong). Then another teenager informs the T-1000, "Yes, he's just over there!" There would be no way for the T-1000 to have known that John would be at that precise place and time.

Inexplicably, after the female guard strikes the T-800 across the face and breaks its sunglasses, she is shoved to the floor and rendered unconscious.

The viewpoint from inside the recovery vehicle, looking out just before the roof is torn off on the bridge, reveals the roof had already been set up to be cut away, as there are clearly small cuts along the top of the windscreen at each of the three pillars.

Genetically speaking, it's impossible for two fair‑haired, light‑eyed parents like Sarah and Kyle to produce a child with very dark hair and dark eyes, as John is portrayed in the film.

When the Terminator emerges from the Galleria to catch up with John and the T-1000, he, for no apparent reason, heads left despite there being no indication of which way they'd gone.

When the Terminator begins spraying the police cars with machine-gun fire, the trajectory aimed at the first car shifts such that it ought to strike a police officer who is trying to move clear of it.

If the T-1000 can imitate any person or shape it touches, there is no sensible reason for it to continually revert to the guise of Robert Patrick in a police uniform after the Connors have recognised that disguise. It could fulfil its objective far more easily by adopting alternative identities to hide its presence and dispatch the Connors before they even realised. Possible explanation: it is likely the T-1000 understood that a uniformed police officer would be the type of person most likely to be left alone and permitted to go wherever he wished without being challenged or impeded, particularly at security points such as the prison's gate and front desk. Indeed, he is regularly waved through or buzzed in at those spots without question.

Towards the end, the T-1000 instructs Sarah to "call to John" in order to draw him out. Having touched Sarah, it could impersonate her (we know this is possible because it had already done so for John's stepmother). Rather than trying to get Sarah to "call to John", the T-1000 could simply have done it itself, thereby saving a great deal of time and effort.

When they first steal the estate car, Sarah tells the Terminator to stick to the speed limit to avoid being pulled over. Later that night the Terminator is driving with the headlights off. Despite being able to 'see everything' with his infrared vision, driving at night without headlights is a surefire way to attract the attention of the police.

The Terminator heads straight to the back of the shopping centre and, despite having no notion of where John might be anywhere within the vast, bustling complex, finds him with ease.

Dyson is prepared to sacrifice his career — and ultimately his life — to obliterate the remnants of the original Terminator and any documentation relating to them and their reconstruction. Yet even in 1991 a company like Cyberdyne would likely have had most, if not all, of its data backed up off‑site, so Dyson would have known that, apart from destroying the chip and the arm, his actions were futile.

Composed of liquid metal, the T-1000 can rotate his face without moving his body merely by reshaping that area. That manoeuvre is no harder for him than moving an arm or a leg, or reforming a region disturbed by a bullet impact. Yet he displays long, unnecessary pauses after bullet strikes. And since he doesn't actually see through the parts that resemble human eyes, there would be no real need for him to flip his face either.

The Terminator states that the T-1000 can replicate "anything it samples by physical contact". However, it is later seen mimicking objects it never actually touches, such as the red-headed prison guard, where only the sole of his shoe made contact. It also copies the motorcycle police officer's helmet and sunglasses without ever touching them. If it can copy what it merely observes, there would be no need to await physical contact.

Clearly, the discovery of the cyborg arm is of paramount importance, yet Kyle Reese's body is never mentioned, nor is Sarah ever questioned about him ("Who is the dead man who was found with you at the factory?"). Moreover, although he might be listed, at least temporarily, as a "John Doe," one would expect that an examination of his corpse would show there is no record of his existence whatsoever: no dental records, no fingerprint matches, no birth certificate — absolutely no traceable information about him. They would not, of course, conclude that he had come from the future, but the complete lack of any record would be, to say the least, a curiosity.

At Enrique's, the dogs pay Bob no attention, which ought to suggest that he is a Terminator.

John tells the Terminator that his father recited the "No fate" speech to his mother. In the first film, however, Reese only tells Sarah the line "The future is not set".

The T-1000 asks for John's photograph. However, once he sees it, he wouldn't need it, as it would be no harder for him to produce one in his hand than to form hair on his head or flaps on his clothes.

At the steelworks the T-1000 could have "taken on the T-800's appearance" after fighting him to fool John. Instead, he pursues Sarah in his police officer guise, which is illogical.

The heat required to liquefy the T-1000 into whichever form he chooses would readily melt any microchip that might serve as his power source. Moreover, the colouring used to help camouflage him in the guise he adopts is not present during his shape changes; it seems to materialise from nowhere and is always available in ample supply.

The T-800 attempts to shoot one of the men in the head when he tries to force him to release John, a reminder that, even though he's been tasked with protecting John, he remains, after all, a Terminator. Earlier in the biker bar, however, when three bikers burned him with a cigar, struck him with a pool cue and stabbed him, he confines his retaliation to wounding them and deliberately refrains from killing any of them.

Once the Terminator's mechanical arm is released from the cog, his real arm, sheathed in a black sock, can be seen beneath his leather jacket. The silhouette of a wristwatch under the sock is also discernible.

John Connor appears to become noticeably taller, despite the film unfolding across just two days (see also Trivia).

Steam throttles are plainly visible when the Terminator flings the motorcyclist onto the cooker.

An obvious stunt double for Edward Furlong rides the motorbike during the chase in the drain; it is clearly an adult and not the 12-year-old Furlong.

The Terminator drives a knife into a biker's shoulder, pinning him to the pool table. The blade is not long enough to pass completely through the biker's shoulder and still remain lodged in the table so as to leave him entirely unable to move.

In the Escape from Pescadero scene, when John, Sarah and the Terminator get into the lift, the T-1000 pries the doors open and is about to step in. The T-800 then blasts his head open with a shotgun. We are briefly shown a camera angle from behind the T-1000, and before the shot is fired we can clearly see the inside of the model head used for the effect. When the shot is finally fired, the head then pops open to produce the effect of it being blown apart.

A clearly visible stunt double stands in for the Terminator when he swings his motorbike around behind the cars after first spotting John Connor on the motorway.

When the T-1000 rides the police motorcycle up the stairs, the tyres have been swapped for knobbly ones. The bike the T-1000 is riding is a Kawasaki KZ1000P, not a Harley-Davidson as is often believed; the Kawasaki, with its 1,000 cc inline-four engine, will obviously sound different from a 45-degree V-twin Harley, but that does not explain the apparent alteration of the chassis and wheels.

(at about 57 minutes) Shortly after the T-1000 clings to the rear of the commandeered police vehicle while fleeing Pescadero, a conspicuously fake dummy is visible being dragged as the vehicle rounds the corner.

A conspicuous stunt double stands in for the Terminator as he bursts through the wall of the "clean room" to rescue Sarah Connor.

It's clear the stunt double is wearing aluminium foil as the T-1000 clings to the helicopter's nose.

During the chase involving the pick-up and a tanker lorry, moments before the tanker first rear-ends the pick-up, the Terminator — who is behind the wheel of the pick-up — can be seen violently jerking the steering wheel from side to side even though the vehicle stays on a straight course.

The tanker ploughs through the remains of the helicopter and then the armoured SWAT van, yet the front grille remains intact until the minor collision when it shunts the "Shead truck."

During the Pescadero sequence, Sarah rushes to the lift and halts as the Terminator steps out. As she turns to dash round the corner, a length of marking tape is plainly visible on the floor. (Visible only on the 4:3 home-video transfer.)

You can clearly make out a stunt double standing in for the Terminator as he swings his motorbike around the T-1000's rig, immediately before grabbing John Connor off his bike in the tunnels.

When Sarah first encounters the Terminator in the hospital corridor, he hurls one of the guards through a window; the actor is clearly replaced by a stunt double.

When the lorry plunges into the river, both windscreens are shattered and come off the vehicle. Moments later, in the next shot, they are still in place but covered in cracks.

As the T-1000 addresses the motorbike officer, the actor's breath is visible in the cold air.

Whilst the T-800 walks through the bar and passes the jukebox, a window reveals the waitress poised for her cue.

Adult stunt rider Larry Linkogle doubles for Edward Furlong; it is readily apparent that he stands in for him during the motorbike chase.

While John and the Terminator are in the telephone box, damage to the phone is already apparent before the Terminator bashes it in; this may only be visible in the pan-and-scan version.

Before the T-1000 impales the Terminator with the crowbar in the steelworks, the Terminator is pulling himself along on a single arm. As the "stump" moves forward and then back, you can spot the string pulling it.

When John and the Terminator reach the hospital, the Terminator smashes the glass to open the gate, but you can already spot exactly where the glass will shatter.

During the canal chase, when the Terminator lifts John Connor from the dirt bike — a cut lasting only one-and-a-half seconds — the T-1000 visible behind them is actually a blue-screen composite, noticeable from the disparity in contrast and image clarity between John and the Terminator in the foreground and the T-1000 and the lorry in the background.

When the two Terminators are battling in the corridor, the plasterboard is already damaged before the T-800 hurls the T-1000 into it.

During the escape from Pescadero, a shot taken from outside the vehicle shows the T-1000 flinging its crowbar-like arm through the shattered rear window. In the upper-right corner of the frame the backdrop cuts off suddenly, exposing the edge of the rear-projection screen used to film the sequence.

After Sarah lowers the Terminator into the molten metal, John turns and embraces her, revealing the "fake ear" plugs they wore during the filming of the shooting sequences.

As the Terminator reverses the police car across the Pescadero car park (immediately after the vehicle's rear bumper scrapes the surface, throwing up sparks), the disguised stunt driver is visible in the centre of the rear window/boot.

By the time the Terminator destroys it with a grenade, the tanker lorry's front grille has already been damaged.

As the helicopter ascends over the Cyberdyne building, the roof should be visible; instead, the black glass frontage is merely a flat façade with no structure behind it.

As the two Terminators grapple and hurl one another through walls in the shopping centre, the wall on the right-hand side of the screen is clearly made of thin paper, barely an inch thick.

While the T-800 pursues John, he skids in front of a blue Ford, which swerves and is hit by two vehicles, one of them a yellow Jeep. However, on closer inspection the cars are already damaged from earlier takes.

At the end of the first film, one of the original Terminator's legs was left intact on the factory floor, yet in this instalment there is no trace of it at Cyberdyne.

By the end of the canal chase, when the Terminator halts and glances back at the burning lorry, the cuts showing him drawing his shotgun, cocking it, stowing it and then riding away all occur within roughly 15 seconds. However, the shadow thrown on the left-hand canal wall climbs markedly with each cut, indicating that several hours — not merely a few seconds — have elapsed between those shots.

The Terminator shows black edging around him when he is hurled into the steelworks, indicating he was superimposed during post-production.

In the opening engagement, just as the blast strikes, a soldier can be seen sprinting towards a mound of earth and, once he stands past the "matte" line, half of his body disappears.

At the steelworks, while firing at the T-1000, Sarah loads five shells into her shotgun yet fires seven times.

When the Terminator first fires into the T-1000's torso, knocking him to the ground, the T-1000 regenerates, seals the bullet wounds and then gets back to his feet. However, a close examination of his injured form prior to regeneration reveals the entire right side to be unnaturally stretched and distorted — an artefact of the visual effects needed to accommodate bullet wounds of that size on that side of his body.

It is obvious that breakaway glass was used when the Terminator smashes through the clothes shop's window: there are no small shards, and neither his skin nor his clothing are cut, despite him flying cleanly through it, landing on it and becoming covered by it.

Rather than a model being employed for the T-1000's final freezing shot, it is clearly Robert Patrick in make-up effects who is used, as his hands twitch slightly while he freezes, staring at his arm.

During the rescue of Sarah, in the shot where the woman wearing a cast strikes the Terminator in the face, his head turns to one side and the left lens of his sunglasses still appears intact; it isn't until the cut to a different angle, when he looks back at her, that the sunglasses look damaged.

When the recovery truck first mounts the bridge pylon, the dummy in the driver's seat appears to have a full head of hair, but after the vehicle collides with the main structure the wig detaches from the dummy's head and falls into the centre of the steering wheel. In the following shot from the front of the truck, the dummy is plainly bald.

The second police car blown up by the Terminator outside Cyberdyne appears to have two panes of glass on the driver's side, with a hole already present where the grenade strikes it.

Dyson sustained a gunshot wound to his left arm. When they went to Cyberdyne, he tucked his left hand into his trousers pocket to support the injury. Later, upstairs in the laboratory, he was seen holding and using a torch with his left hand. Moments afterwards his left hand was back in his pocket.

The wide shot of the T-1000 in its liquid state, with separate puddles coalescing, appears to place the nearest puddle in front of a rear-projection screen. A line along the boundary between foreground and background is discernible, and a brief puff of steam is released from the left of the screen to help create the impression of a single continuous take; the steam striking the background screen and rebounding further reveals the effect.

In the biker bar, the T-800 plunges a biker's own knife into his shoulder. When the biker tries to pull the blade free, his jacket ripples, revealing the outline of a concealed pad in which the knife is caught.
