Continuity mistake: The location of the staircase leading up to the supercomputer's control console changes. When they first enter the computer, it is at the back of the computer behind a lot of electrical machinery and circuits. When Ross comes down to try and get the screw out of Gus's mouth, the staircase has moved right next to the entrance of the computer (where Vera gets turned into a robot later on).
Continuity mistake: The firetruck's ladder Jimmy climbs up during the chemical plant fire changes between shots. In the first shot its a white-framed ladder at a pretty shallow angle. The ladder in the second shot changes to a black and orange one which is at a much steeper angle and the rungs are spaced further apart. Also in the second shot he is much closer to the top of the ladder than the first shot, and there is no way he climbed up the ladder that fast.
Continuity mistake: When Vera is getting sucked into the computer, she has white gloves on. Seconds later, during her robot transformation, there is a full screen close up of her hand without any glove. Then, when Vera emerges from the wreckage of the computer a few minutes later, she has her gloves on again.
