Visible crew/equipment: During the "target acquired" chase scene when the red pickup truck flips over after going through the split semi-trailer there is an overhead shot shown of the action. The next shot when the T-X looks in her rear view mirror at the action, the camera crane that filmed the previous overhead shot is visible in the background. (00:32:25)
Continuity mistake: The driver side rear view mirror is broken on the police car as it chases the tundra truck onto a front yard, but after leaving the yard the mirror is back intact. (00:34:55)
Continuity mistake: When the T-800 first drives the truck into the Vet clinic, the truck has crashed into the building, so that the doors are inside the clinic. Yet in the very next shot when he gets out, the truck has moved back so that the doors can open cleanly, without the T-800 backing the truck up. Then when John escapes the cage and he runs into the T-800, you can see the truck inside the clinic. It is now more than halfway inside the building. (00:24:15)DenizenZERO
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.
Continuity mistake: When the Terminator is hitting the T-X with the fire extinguisher, she puts her fist up and punctures it so the Terminator chucks it down on the floor. We see it on the floor again, but when the Terminator is running towards the T-X you see where the extinguisher was but now it has vanished. (01:18:55)
Continuity mistake: During the shooting scene at the cemetery, note one of the stones (rectangular from the left) behind T-101 when he comes out carrying a coffin. You can see it has 5 holes - 3 left, 2 upper right side. However, a few seconds later, it has 6 holes, but their position has completely changed, 3 upper side, 3 right side. (00:55:25)
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).
Continuity mistake: When the T-X steals the car in the beginning, she's weaving in and out of traffic and from her view we see that she is coming up to a truck in the right lane. The view changes to view from outside the car and she's turning into the right lane and driving straight ahead. The truck is gone. (00:07:50)MCKD
Continuity mistake: When John, Kate and Arnie are at the cemetery getting the weapons from Sarah's casket, Kate pulls a handgun on Arnie. He looks up and is facing his right with his legs turned in that direction. They go back to Kate and then back to Arnie. Now he is turned to the left. (00:51:05)Brian Watts
