Other mistake: When the aqueduct chase has finished, and the T-1000 strolls out of the fire, the semi is hardly burning in the background. Considering that the semi has just violently exploded, and the small bridge it just crashed into was nearly flattened, it seems odd that it shouldn't be burning (very tricky to see, best use zoom in). (00:38:40)
Other mistake: Just after the top of the truck's been sheared off, the T-1000 sticks his head back up and pushes the shattered windscreen out. He then steers quite severely right, then left, but given how narrow the area is he's driving down, that would have slammed him into both walls. (00:35:25)Jon Sandys
Other mistake: Repeated footage of a car crashing is used during the chopper/SWAT van chase. The clip is first seen just before the onset of the shootout between Sarah and the T-1000. The same clip is shown a second time as the two vehicles are about to pass up the nitrogen truck just before the chopper flies over a pedestrian bridge.
Other mistake: As the cop is walking towards the coffee machine, he steps on the T-1000 (disguised as the floor). The cop proceeds to the coffee machine and buys a coffee while the T-1000 turns into the cop. The T-1000 only touches his shoe, so shouldn't be able to copy his appearance. (00:51:00)oobs
Other mistake: In the scene in which the T-1000 arrives at Dyson's home, he sees the files burning in the trash can. We know this is happening as the others are in the Cyberdyne building as the police radio, just a few moments afterwards, calls all officers to the area. There is unburned paper on top of the pile. Given all of the time that they were in the Cyberdyne building, there should have been a large amount of ash in the trash can. There was no sign of strong wind to have blown the amount that should have been present. There is an incredibly small amount of ash in the can when it is shown, it just isn't possible with the elapsed time. (01:44:00)Knever
