Factual error: The movie was meant to be set in Oregon, but it was actually filmed in Shreveport, Louisiana. In the scene that has Tracy leaving the apartment complex where Bafford (Mr. Smith) is, she is worried that she is being chased by a jogger who may possibly be Mekes. In the background, during the shot where the jogger first appears, a brown sign can be seen. These specific signs are unique to Louisiana and describe the history of certain locations, this one obviously being Shreveport.

Continuity: During the van chase sequence, the van door is open for the first few minutes. Then the van makes a sharp right turn and immediately it cuts to the door which is now closed. In the immediately following shot, it's back open yet again.

Continuity: As Tracy Atwood is catapulted from the open van door onto the taxi's windshield, the side view of the taxi shows the side windows have a curtain or black film behind the glass. Immediately after, the next side view shows no curtain or film, and the driver is now visible. Slo-mo is not necessary.

Factual error: Approximately one hour and 28 minutes into the movie, the Oregon license plate on a Ford is shown. The plate reads "WIE 1Z0"..Oregon does not use the letters "I" or "O" on its license plates as they may be mistaken for "1" or "0".
