Continuity mistake: When the FBI meets them in a parking garage to pick up & protect Cindy Crawford as they are driving away, the partner in one car, Cindy & Baldwin in the other car the partner is shot in the head, creating a blood splatter on the window - however if you look carefully this blood splatter is already on the window when they show the car turning a corner in the garage - right before he is shot!
Continuity mistake: From the point in the film where Cindy Crawford goes into her office to meet another lawyer, she is wearing a vest-like top. After her apartment blows up and while she is on the run with William Baldwin, she is still wearing the same top. However, when it goes to a scene in where Cindy and Baldwin are in Baldwins car, Cindy is wearing a different top, even though she had no other clothes with her to change into. Even later it shows Cindy changing into another top. But where did she get it?
Factual error: When Baldwin is in the old Caddy convertible driving alongside the train, he sets the cruise control so that he can jump into the train. There are three problems with this. I seriously doubt a Caddy that old, it looked like early 70s, would have cruise control, but they were luxury cars, so it is possible. They show a shot of him setting the cruise control, and it is on a modern-style control stalk, very typical to late 80s and early 90s GM cars. Since the ground along a railroad track is not pavement, it would be very bumpy and uneven, and virtually impossible for the cruise control to keep the car going whatever speed he wanted it to go, going over dumps and holes like that.
Factual error: When the Russians find out Kirkpatrick's name and pull up his personnel record on the computer, his police employee ID card lists his date of birth as 6-23-1965 and the date of issue of the card as 1978, making him only 13 years old at the time of issue.
Continuity mistake: At the hotel, when the Russian calls Kirkpatrick and offers him $250K for the girl, there is a big telephone lying on the bed by the pillow that wasn't there before (nor is it after) his telephone call.
