Goofs

As Ben informs Barbra that the house is secure and all windows have been sealed up, a plain, uncovered, unsecured window is visible right behind him.

The live television remotes all seem to be taking place in daylight, although it's supposed to be the middle of the night when they're being aired.

Ben finds a pair of shoes and puts them on Barbra's feet, but in the very next shot where she's sitting on the couch, she is not wearing shoes nor are they any in the shot with her.

When the first zombie gets to the house where Barbra is hiding, it's still daylight. Moments later it appears to be the middle of the night.

When he first appears, the cemetery zombie's coat is open and unbuttoned. During the fight with Johnny and in subsequent scenes, two of the buttons are fastened.

Sheriff McClellan has large shells on his belt, which would not possibly fit in the rifle he is carrying.

Tom tells Ben that he and Judy were on their way to the lake to go swimming. The events are taking place in late April. It would be far too cold for swimming in Pennsylvania at that time of year.

One of the lines assigned to the news reader is a quote from the chief of police in Camden, North Carolina. The city and county of Camden have a consolidated government with a sheriff and no police chief.

It makes no sense that the people who died are made sentient again but only the instinct to eat.

There couldn't have been that many zombies as depicted in the movie, because there aren't that many dead people, at least not that aren't buried and decomposed or were cremated.

On the Laserdisc and the 1997 DVD, there is distorted audio and music at the beginning of the film. However, this was intentionally done to trick the viewer into thinking they bought a low-quality copy of the film.

The first time the dead body is seen at the top of the stairs, the face has been eaten away. Later when the body is being dragged away, the rug conveniently covers the face, but the face can be seen for a split second, and it is clearly normal.

When Barbra runs the car into the tree, it is already dented before the impact (see trivia).

When Barbra is told not to look at the defeated zombie that tried to attack her, his eyes are moving to look at her.

When Tom, Judy, and Ben are going to the gas pump, there is one shot where it is clearly day (or at least dawn), even though the scene takes place in the middle of the night.

It becomes a plot point that the farmhouse's cellar has only one entrance, which leads into the living room area. However, early in the film when Barbra approaches the farmhouse, an outdoor cellar entrance is seen.

As the cemetery zombie is shown pursing the LeMans rolling downhill from inside, a car can be briefly seen in the distance that was never seen prior to this shot. This car possibly belonged to a crew member and was likely in the shot by accident.

One of the zombies eats a hand from the torched truck, but the hand does not appear to be burnt or charred.

When Barbra and Johnny arrive at the Evans City Cemetary at the beginning of the movie, Johnny complains about having to drive 3 hours back to Pittsburgh. In reality, Evans City is only 28 miles from Pittsburgh.

When Ben removes the planks of the door, you can see written "upper right corner" on the one removed from that position.

On the Laserdisc and the 1997 DVD, the image at the beginning of the film is blurred. However, this was intentionally done to trick the viewer into thinking they bought a low-quality copy of the film.

When Harry and Tom first enter from the cellar, Tom yells "Don't shoot! We're from town!" We hear him say "We're from town" but his lips never move.

The sound coming from the phone when Barbra (and later Ben) try to dial for help does not resemble any known telephone company signaling from the time, particularly anything from the kind of small-scale, electromechanical switching equipment that a farmhouse in rural Pennsylvania would be served by.

Ben's hammering is always out of sync.

When Ben kills the first two zombies by the truck, there is an audio mismatch between his blows and the impact sounds.

When Ben is telling Barbra the story about the zombies chasing the gas truck, his mouth does not match most of the words he is saying.

When Barbra rounds the corner of the farmhouse while searching for an entrance, someone is visible side-stepping away from the alley and crouching behind some bushes and posts of a shed.

When Ben is bent over a ghoul he just killed in the woods, a hand waving the character away from the body and out of the scene can bee seen.

As soon as Barbra walks into the farmhouse, there is a crew's hand in the shot before the stuffed animals.

At the beginning, when Barbra and Johnny are approaching the correct grave site, a figure in black jumps behind a large headstone behind them.

When Johnny is teasing Barbra in the cemetery, he runs away as the first zombie approaches. He stops and looks back at her, and just as he stops, someone ducks into the trees in the background.

In the opening scene, Johnny tells Barbra that they have a "three-hour drive" ahead of them to return home to Pittsburgh. However, later in the film when the TV broadcast is listing local rescue stations, all of the town names given are located in the greater Pittsburgh area.

When Barbra enters the farm house, the door is unlocked. It is unlikely the people barricading themselves in the cellar would have forgotten to lock the kitchen door.

In the first scene, in the cemetery, Johnny is killed by a big stone smashing his head and brain. And that doesn't prevent him to get back to life, although smashing a brain is supposed to kill the zombies.

The cemetery ghoul doesn't eat Johnny after either knocking him out or killing him. Instead, it goes after Barbra. Yet when Tom and Judy are killed in the explosion, the ghouls help themselves to the bodies.

When Johnny appears at the farmhouse, it's been hours since he died in the cemetery. He should have been among the ghouls surrounding the house long before this.

The little girl as a zombie gets a garden shovel and walks to her mother and stabs her to death. The woman has plenty of time to run away or defend herself, but she doesn't. She just lies down and is stabbed to death.

When the characters are first arguing about whether to stay upstairs or hide in the cellar, the shadow of the boom mic is clearly visible across Ben in one shot.

Ben contradicts himself all through the story as he tells Barbra about the gasoline truck. First, he says he had just gotten into a truck he found to listen to the radio when this happened. Then he says that when the gas truck came by, it was all he could do to miss it - inferring he was driving. He also says that it was "screaming by" and that zombies were chasing it on foot and keeping up; however, all the zombies can be outrun, even by Barbra. He also says that the truck was on fire during this chase and there were zombies hanging onto the truck, yet fire is the one thing that scares zombies.

At about 24 minutes, when the wood is being nailed in place to secure the house, the nails used are far too small to have any significant effect.

One man refers to the zombies as dead, as he is being interviewed by a reporter. Dead refers to the absence of life functioning, therefore they are not dead, because if they were, they would not be sentient.
