Continuity mistake: In the scene were John, Kate and the Terminator find the RV, when John says to Kate, that Scott's death wasn't her fault, she is sitting in the passenger seat of the broken down Hearse. Then in the next shot Kate completely disappears and reappears when the Terminator mentions the TX is going to kill Robert Brewster.
Factual error: All over the particle accelerator you can read about the dangerous magnetic fields that are caused by it. the radiation that is created by the accelerated particles is mentioned nowhere although there is no possibility to find a wall without radiation warnings in a science lab with a real accelerator.
Continuity mistake: When the TX's crane is pulling away after destroying the building facade, it is seen from the high angle that the top of the cab is clean. When the crane is shown again the cab roof is covered in cables and other debris. Also note it remains this way until catching up with Connor in the Tundra truck and then the crane is clean like it was run through a car wash.
Revealing mistake: During the big fight between the two terminators, the male grabs the female and smashes her head into a toilet. If you watch carefully as soon as her head hits the toilet it cuts seems to cut to another shot. (Easier to see in slow-motion).
Continuity mistake: When Kate takes a gun out of the coffin at the cemetery, you can see she puts her finger on the trigger. In the next shot, her finger is back around the handle and not around the trigger.
Continuity mistake: The amber parking light lenses on the hearse are mismatched and change several times thoughout the hearse scenes (note the Cadillac crest on the left side lens).
Other mistake: At the end of the chase, the crane truck flips and one of the wheels falls off. If it was that loose, it should have come off when the T-X did a right turn.
Suggested correction: Maybe it became loose enough to come off after the right turn.
Continuity mistake: In the crane chase scene, there is a point where the last remaining ambulance collides with the back of the Toyota. You see the ambulance back off and the right headlight is smashed and the housing is dangling. The headlights are also off. The scene cuts to the rear-view mirror of the Toyota. You briefly see the same ambulance with its lights on and both headlights are intact. Shortly thereafter, they cut to a behind-the-back shot of Arnold as the same ambulance starts to flip. The tail lights are on. It wouldn't be brake lights since there is no driver and the Terminatrix certainly wouldn't remotely apply the brakes.
Continuity mistake: During the chase scene with the veterinary truck and the terminatrix, the damage to the truck is constantly changing. In one shot the hood of the truck is bent upward, in the next shot it is straight and undamaged.
Continuity mistake: When the crane flips over the arm is missing when it is seen sliding across the road.
Continuity mistake: When the TX runs the crane through the glass corner of a small building while chasing the tundra truck, the flashing orange lights on the top of the cab are missing. These lights return on the next shot.
Continuity mistake: A headlight breaks loose on the ambulance after hitting Arnold's motorcycle. The next shot when the TX is looking in her rear view mirror, the ambulance has two flawless headlights.
Continuity mistake: The Terminator is following the crane at the rear corner when the TX moves the arm out allowing the hook to hit parked cars and telephone poles. During the overhead shot there is no Terminator behind the crane.
Continuity mistake: During the chase scene with Kate's truck and the T-X in the crane, the driver's door disappears and reappears several times.
Continuity mistake: During the chase scene when the T-X is driving the crane, the legs of the crane are out in some shots and retracted in other shots.
Continuity mistake: When the Terminator breaks into the van the broken glass changes from smashing it to getting in.
Revealing mistake: In the driving scene after the first run in with the TX, the T-850 is driving the truck, John is in the passenger seat, and Kate is locked in the back. The T-850 has to cut open his abdominal area to pull out the nuclear power cell that has been damaged, and dispose of it. In the shot before he begins cutting, you see the T-850's chest is flat as it should be under his shirt. But once you see him begin cutting into his abdominal area, the top of his chest has a ridge. This is an obvious show of the prosthetic chest the actor scoot up against to be as his chest and house the fake skin, metal, and power cell for the scene.
Plot hole: It makes absolutely no sense why the Terminator, who is a programmed killer, chooses not to kill anyone in this film. In Terminator 2, he didn't kill because John, who was his master, ordered him not to. In this film, we learn that John is not his master. Kate Brewster is. And she spends most of her time complaining and trying to escape from John and the Terminator. She certainly wasn't gonna bother giving the Terminator a pep talk on no killing. So it just remains a plot hole.
Suggested correction: Kate Brewster told the Terminator not to kill when she reprogrammed him in the future. It's a logical order to give since its mission is to protect. It's likely John gave her that idea in the future when telling her about the terminator from T-2 (before he died of course) who he gave the same order to.
I agree, but it is also possible that Kate programmed him not to kill anyone.
That's what I said.
Revealing mistake: When the Terminator, Kate, and John are escaping the cemetery, they come down a winding road and drive in front of the camera in a hearse. Both Kate and the Terminator have been replaced by stunt drivers.
Audio problem: When Arnold makes the slow turn at the cemetery from Dr. Silberman's view, he starts firing his weapon at the police but we don't hear it. In the very next shot, he repeats the same action but we hear it this time.
