Factual error: In the final act, when the T1000 falls into the molten steel, he sinks and thrashes around rather like a human in water. However, molten steel has a density of around 8 g/cc - about 10 times that of a human. Immersed in such a fluid, he would sit on the surface and fry. Nothing in the movie gives us the impression he has a huge density approaching that of iron. If he did, he'd weigh about 700 kg and would have collapsed the suspension of the police Harley, been too heavy to fly the police helicopter and collapsed the back end of John Connor's car when he leapt on it.

Continuity: This is during the Special Edition's chip removal scene. There is a point where the shot is of the Terminator's POV. In the foreground a pair of pliers moves vertically through the frame. However, in the "reflection," Sarah Conner is already tinkering with the Terminator's head. Apparently Linda Hamilton (who played Sarah) and her twin sister were out of synch for that shot.

Continuity: When John Connor holds the Terminator's jacket up to the light in the shed in Mexico it's full of holes. You see the back of it when they leave (to chase Sarah) and there are no holes.

Revealing: In the beginning of the film, when the biker is thrown onto the stove you can clearly see the valves where the steam is coming from - it's NOT from his hands.

Visible crew/equipment: Camera lights are reflected in the glass door in the shot behind Dyson as Sarah Connor laser-scopes him.

Visible crew/equipment: [Special Edition only] Shortly after the Terminator shoots up the police cars outside Cyberdyne, the SWAT team enters the building through the front glass doors. When the shot changes from outside the building to inside, the camera dolly and cameraman are visible in the reflection on the glass doors and windows.

Visible crew/equipment: In the escape from the hospital where the car is driving fast in reverse, the stunt driver's head is visible sticking up from inside the trunk driving the car from the back. It's too far back to be John Connor's head.

Continuity: In the scene where the Terminator and John are at the pay phone John picks the gun off the floor, it's cocked when it's in his hand, but as soon as he passes it to the Terminator, it's not cocked any more.

Continuity: During the chase scene after the T-1000 commandeers the tow truck, the shadows are inconsistent from shot to shot.  Understandable, as each shot was made at different times during the day, but still noticeable.

Continuity: As the Terminator and the rest are escaping from Cyberdyne Systems in the police van, the helicopter explodes about five feet before it hits the van.

Visible crew/equipment: When Arnie is airborne on his cycle in the canal scene, you can faintly see the wires holding up his bike - from just around his shoulders right before he lands to until it switches scenes.

Revealing: In the scene where Terminator appears for the first time he arrives in a sphere that burns everything in its way, the tires from the trailer are affected by this but the trailer doesn't fall down like it should.

Continuity: In the car chase just before the final encounter in the foundry, the T-800 slams on the SWAT van's brakes and the helicopter slams into it, crushing the choppers front. A second later it is in reasonably good shape.

Revealing: Just before the T-1000 crashes the truck into the bridge and the following shot you can see briefly that it is a dummy in the drivers wheel. The most noticeable difference is the dummy has black hair compared to the T-1000's brown hair.

Revealing: Obvious stunt double for John Connor when he takes a wide berth from the street into the aqueduct. His hair, for example, is no longer across his forehead.

Revealing: When the T-1000 is firing out of the hole in the windshield of the chopper, a close up shot shows that there is clear tape around parts of the window keeping all the little bits of glass together.

Continuity: During the aqueduct chase the damage to the semi's grille is severe, then is not. This happens about three times (most noticable when it is driven into the aqueduct).

Revealing: When the two Terminators first fight in the steel mill, in close - up shots the T-1000 is played by Robert Patrick, but in medium shots it's a stunt double who doesn't resemble Patrick very much at all.

Continuity: When Sarah runs into the corridor to smack the guy with a broom handle, we see a close-up of him having just emerged from a store-room and turned round, standing right next to the door. There's then a very brief shot of Sarah swinging towards him, then a white flash. When we cut out to a wider shot, he's suddenly in the middle of the corridor, with no time to have moved there.

Continuity: In the scene where the Terminator has grabbed John and won't let him go until he tells him to, the Terminator almost shoots two guys who come to help. John tells him to put the gun down, which he does. Now, when John picks up the gun to hand it back to the Terminator, it goes from being cocked (the hammer pulled back) when it is in John's hand, to uncocked when Arnie takes it, to cocked again when he puts it in his belt.
