Goofs

At 1:05 after the party, the wall clock behind George jumps from 12:27 to 12:20.

Franny Claire's sitting position changes as Willis is reading The Cat In The Hat to her in the library.

(At around 1h 18 min) After Catherine slams the wine glass into the soup, the wine glass changes position.

When Mare is talking to her husband in the kitchen, her grip changes between holding a coffee mug and a knife.

Catherine finds a ring in the window and puts it back on the windowsill, but she is wearing it in some scenes before she actually goes back to the windowsill to put it on.

The $50 bill in the envelope for Cole has a picture of Andrew Jackson on it.

The paintings George's cousin paints are described as watercolors by the family, but the paintings are impasto style, likely oil or acrylic, and not achievable with watercolor.

A turkey vulture on the roof outside the bedroom screeches but the Netflix subtitle misidentifies it as a raven.

There is a 1970s model police car that has no mention of 911 or a unit ID number.

When George cranks up the outboard motor on the sailboat near the end of the movie, it starts up and starts moving the boat but the engine noise is low and deep like a large, inboard engine, not a small typical two-cycle outboard of the time.

When the sheriff visits the woman in the hospital, the flag shoulder patch on his right shoulder is backward. From the side, the flag is 'normal', flying from left to right. It should be backward, flying right to left, so that it appears he is advancing.

When George leans over the hood of his car to examine the blood drips, he then receives the third drip on his face. One would not lean over, then crane their neck sideways in that position, but rather stand and look upward. This was likely done for dramatic effect.

When speaking about HR in regard to the school, HR as a term didn't exist during that time; it would have been called personnel.

In the opening birthday party scene, Catherine calls a group of little girls "you guys," and then a moment later calls her mother and father "you guys." In 1979, "you guys" was not used to refer to girls or women.

Justine's Volvo 245 is clearly a post-1980 model year. The model was made until 1993, and this car looks like one of the really late-model years in the 1990s.

Referring to the possibility that George and Catherine's house is haunted and the likelihood of other haunted houses in the area, Bram tells them that they're in "Headless Horseman country." The film takes place in fictional Chosen, N.Y., in the upstate Hudson Valley, presumably around the actual filming locations, such as Rhinebeck and Kingston. Washington Irving's story about the Headless Horseman, "The Legend of Sleepy Hollow," was set in Tarrytown, N.Y., which is 75 to 85 miles south of the film locations.

The sheriff's uniform has generic police badges on his jacket's shoulders but no insignia on his chest or back, nor a name badge. Police officers have the same shoulder badge and no name tag.
