At the end of the phone call from Cinnamon, Rollin hangs up the phone. When he then sits down to put on his shoes, the handset from the phone is sitting on the table.
Just after 18 minutes. The tape has been shown to be near the end of its 42 minute run time. However, in this shot from the ceiling, the take-up reel only has a small amount of tape on it and the other reel is mostly full. It should be the other way around if the tape was almost over.
During the balloon shootings, the woman in the blue bikini runs past Cinnamon away from the boat (Cinnamon is headed toward the boat), ostensibly to get away from gunfire. Moments later, she runs past Cinnamon (at the boat) in the opposite direction (to right of screen). To do this, she would have had to run towards the shooting before reaching the boat. Two seconds later, she again runs past to left of screen (toward the shooting). Another woman in a frilly red dress is used in the same manner.
When Rollin and Cinnamon are escaping in the boat at the end, the background seen through the boat window shows a large cliff-like mountain with dark green trees far in the distance. But the long shots of the boat show it approaching a much-nearer small hill with light green trees and bushes.
Cinnamon tells The Concessionaire that she wants a piece of string so many yards in length. Since this story takes place in Eastern Europe she should have used the metric system.
During the briefing segment, Cinnamon said that the taped conversation is forty-five minutes long. The tape recorder used is a Craig model 212, which had a maximum reel size of five inches in diameter. It had two speeds, 1 7/8 inches per second and 3 3/4 inches per second. The speed was changed by using a metal sleeve that changed the diameter of the capstan. At the faster speed, a full reel of tape lasted about fifteen minutes; at the slower speed about thirty-five to forty minutes. In Cinnamon's hotel room, the recorder can be clearly seen to be running with the larger, faster capstan in place. At that speed, the tape would have run out with half an hour left to fill.
According to the recording giving Dan his instructions, the record is supposed to self-destruct 60 seconds after breaking the seal. The record actually dissolves 114 seconds after the seal is broken, meaning it should have dissolved about halfway through the message.
At around 33 minutes the red Volvo driving by has California plates.
Although the episode is set in Eastern Europe the sign on the pay phone is written in Spanish.
