Continuity mistake: When Walter is cleaning the floor, the robot comes up behind him and bumps the mop bucket. The bucket does not tip over, but the dirty water sloshed out. In the next shot, the bucket is tipped over in front of the robot. (00:27:00)
Continuity mistake: Allison stands six feet from the doorway as she tosses the lighted flare into the paint shop, at the killer robot, and then everything explodes, and she runs off left. But moments later, after the fire and smoke has died down, the camera pans back from the doorway wreckage, and she is suddenly lying wounded in the same spot where she threw the flare. When she should have been long gone out of there.
Continuity mistake: The perspiration on the girls faces changes while they are up the air vents. In a few shots sweat is dripping from their faces, but in other shots their faces are completely dry.
Continuity mistake: Just before the second technician is killed by the robot's pincer stabbing him through the magazine he is reading, if you look closely you can see the holes in the magazine made by the pincer in previous takes of the scene.
Continuity mistake: When the robots are chasing the girls, the girls are all carrying make-shift Molotov cocktails made out of petrol cans with a rag in the neck. Suzie is hit in the leg by a robot and falls to the ground. The robot then fires a laser at the petrol can by her, causing it to burst into flames, which cover her too and burn her to death. However, when the camera pulls back, we see that her petrol can is mysteriously intact and untouched by the flames.
