The length of the rope that is tied between Jaime's wrists varies between shots of the escape from the van.
The remaining time on the countdown-timer randomly varies between shots, sometimes showing more time remaining than it showed in the previous shot.
The young bandits enter the room some time after the hidden microcassette recorder is started, yet in the closeup shot of the spooling tape-hubs that is seen after the youths start to work at the computer, the tape is shown to be reeling off from the very beginning of the supply-hub.
Mrs. Simpson did not have an alarm-switch key to unlock the campus's security doors, so she could not have "silently" opened the back door to the library, which is very visibly fitted with a blazing-red-painted "emergency exit only --- alarm will sound" latch-bar. There is obviously no key in either of the door's two inside locks, so the alarm would have gone off immediately if Mrs. Simpson had pushed the door open to let her confederates inside.
The shot of the campus kitchen's loading dock that is shown just before the bandit says "we could trap her" is obviously just the unused "beginning" footage of the "Jaime walking onto the lighted dock and entering the kitchen" sequence; a dimly-lit view of Lindsay Wagner can be clearly seen at the far left of the screen as she starts to walk out from the darkness and approaches the lighted dock.
The computer bandit invites his buddies to suggest how much money he should withdraw from the OSI account, yet the eventually-decided-upon amount of $5000 is already displayed on the screen when he first asks the question.
The words on the computer screen do not match the audible words that Rudy is speaking as he is supposedly reading off what the screen says.
Reflection of a light-colored/shiny rigging-cable can be clearly seen in the window of the back door of the van as Jaime and the old lady exit.
When Jamie jumps down from the top of the cabinet where she was hiding, the shot of her from the back is clearly a stunt woman because her hair color is much lighter than Wagner's.
