Mrs. Myerson's voice in the two phone calls sounds different from that of actress Anne Haney who plays the part in a later scene.

In the scene where Kendig is chased by FBI cars in Georgia and spills oil on the road, it is shown as he left it and again a moment later as the FBI cars careen off the road. The splash pattern of the oil on the road is different in the two views.

The movie is plausible up to the point where Kendig was able to transition from the biplane across an open field, under the watchful eye of four people in a helicopter without being seen, to hide in the shack with his radio control box and fly the airplane. This is very incredulous.

When the agents from the CIA and FBI near Myerson's house, his car is in front of the house, but when they start shooting, the car is no longer there.

In the scene at Myerson's house in Savannah, Kendig is getting ready to start typing and glances at a photo of Myerson. When the photo is first shown, Myerson is almost smiling, but the photograph changes several times after this. In fact, each change is intentional and is intended to show Myerson getting more frustrated and downtrodden as the plot progresses, culminating in the picture being shot in the forehead by one of the FBI agents (as explained in the introductory video on the DVD).

When Glenda Jackson leaves her house in Salzburg in her car "to get some ice" it shows her driving instead to a ferry boat which takes her to England, apparently arriving later the same day. The distance from Salzburg to the English Channel cannot be driven in one day.

Myerson's house is supposed to be in a suburb of Savannah, GA, but the address is stated as being in Adairsville. Adairsville is north of Atlanta, more than 300 miles north of Savannah.

Miles mails his first chapter to the CIA in Washington, D.C., but the CIA headquarters building is in Langley, Virginia.

When Kendig puts on his reading glasses in Myerson's office to examine the photos on the wall close up, he looks over the glasses rather than through the lenses to view the pictures. There's no point in putting on glasses if you're just going to look over them.

Agent Ross's passport shows a birth date of 30 January 1930, but actor David Matthau was obviously much younger (born 1953).
