Abfolgefehler: Although the exterior of the railway cars shows the Penn Central logo, the interior of the car bears the Metropolitan Transit Authority (MTA) logo.
Anachronismus: The MTA did not exist at the time.
Anachronismus: In the scene where Wendy Hood has a brief encounter in the middle of the crosswalk with Sandy Carver (approx 30-50 min in), the street corner's kerb in the background (behind Wendy) is wheel-chair accessible. Such ramps did not exist in 1973.
Abfolgefehler: Mikey's watch at his parents' dinner party.
Anachronismus: There is a six-wheeled G.I. Joe "armored personnel carrier" among the numerous toys in the Carver's rec-room. This plastic toy vehicle was not introduced by Hasbro until 1983, ten years after this film is set.
Abfolgefehler: At the beginning the man who gets off the train before Paul Hood slips on the ice. In the end, when this sequence is repeated he does not slip.
Abfolgefehler: The zipper on Mikey's coat as he prepares to go out in the storm.
Anachronismus: The Tampax box glimpsed in the chemist's is a modern design while the packaging in the medicine cabinet is correct for the time.
Filmfehler: Although this is meant to take place in the 1970s, you can see that the globe does not show the Soviet Union or East/West Germany but instead Germany as a whole and the former republics of the Soviet Union.
Abfolgefehler: After her very fumbled sexual encounter in the car parked in the driveway, Elena, in windswept heavy rain, returns to the party house to help her husband who has been violently sick in the downstairs toilet. Though she carried an opened umbrella, her ankle length coat, fully visible onscreen, should have been absolutely soaked and there should have been other evidence of the heavy rain elsewhere on the coat. It was evidently completely dry.
Crew oder Equipment sichtbar: After the keys at the party have been taken, only Elena and Jim are left and talking on the sofa. There is the reflection of a crew member in the window just above Jim's left shoulder.
