Goofs

Although the exterior of the railway cars shows the Penn Central logo, the interior of the car bears the Metropolitan Transit Authority (MTA) logo.

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.

When Mikey Carver is serving wine to Ben Hood you see him tip over the wine glass. In the next shot of the table and Ben Hood, there is no wine glass near him and it has mysteriously vanished. Ben Hood is wiping nothing off of him when he should have wine on his pants and the table. In the next shot the glass has suddenly reappeared and Elain Hood is picking it up and wiping the table.

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.

At the key party, when Ben stumbles upon his colleague George Clair while pouring himself a drink, George has a wedding ring on his left hand. But in the next shot, when George's left hand is in the foreground, gesticulating, there is no wedding ring to be seen. The ring reappears when his keys are picked from the bowl and he leaves the party.

Downed power lines do not flail about like unattended fire hoses.

Early in the film, Ben asks Paul on the phone to be on the 4:40 train on Wednesday, the day before Thanksgiving. Yet, when he picks up Paul from the 4:40 train it's midday and sunny. It should have been getting dark around that time in the Northeast, for daylight savings time started a few weeks earlier.

During the opening credits the train conductor announces "...this train originating from New York's Grand Central Station is back in service..." As many people and every train conductor knows the correct name is Grand Central Terminal. This stems from the location on the railroad line; Grand Central is at the end of the line, hence it is a terminal not a station.

When the train arrives, it has the Penn Central logo on the front. At the time, Penn Central operated the commuter railroads throughout the Tri-State Area. However, electric multiple units such as the M-2 Cosmopolitan would not have used that logo. The first batch was owned by the Connecticut Department of Transportation, and all of those trains would've had the state seal on the front.

Fantastic Four #141 has a December 1973 cover date, and went on sale in September. In no case is it factually correct to say that it was published in November.

The events in this film take place in late November. At that time of year in Connecticut, most of the leaves on the trees would have fallen, and those that remain would be colored or brown, rather than the green leaves that we see all over the trees.

When Ben begins giving Paul the sex talk in the car, his unease causes him to swerve in to the wrong lane (as indicated by the sound of an oncoming car horn and Ben's swerving back into his lane). Yet, the oncoming car never passes them.

There is a yellow plastic Comet container visible near the sink of the Hood home. In 1973 these containers would have been a green cardboard tube with metal top/bottom. Plastic Comet containers did not exist until later.

In the scene where Wendy Hood has a brief encounter in the middle of the crosswalk with Sandy Carver (at the 19:20 mark), the street corner's curb in the background (behind Sandy) is wheelchair accessible. Such ramps did not exist in 1973.

The Tampax box glimpsed in the chemist's is a modern design while the packaging in the medicine cabinet is correct for the time.

Janey Carver smokes Marlboro Lights. This brand wasn't launched until 1977.

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.
