Continuity mistake: There's a bright reflection of a studio light on the wall to the right of the clock on the mantle that appears between shots. (01:04:25)

????

Continuity mistake: As Melanie approaches the pet shop cashier she passes two cages on her right with birds in them. The cage with the two yellow birds that she shows to Mitch is not one of them nor is it behind the second cage where it appears later. (00:02:30 - 00:06:00)

????

Continuity mistake: As Melanie climbs out of the boat, she holds her pocketbook around her arm with the latch facing her body. After she enters the house the latch is facing outward and she's never taken it off her arm. (00:21:50)

????

Continuity mistake: The book on the table to the left of Melanie's brandy glass has been made to look as though someone has been reading it. When we first see it the cover is closed now the cover looks as though it's been thumbed through even though no one touched it. (00:46:55)

????

Continuity mistake: When Annie decides to have some brandy also they cut back to Melanie and the lamp that was behind her disappears. We don't see it again until the end of the scene where it's been moved again. (00:42:55 - 00:45:30)

????

Continuity mistake: The girl in the red sweater's facial cuts get much worse when we see her in the station wagon. (00:14:55)

????

Continuity mistake: At the school Melanie and Mitch pass the front of her car twice on their way to Annie's house. First they stop right at the front of the car as they spot the birds on the monkey bars, then three shots later they walk past it again. (01:29:45)

????

Continuity mistake: After Melanie walks into Mitch's house and puts the cage down we see that there are no birds either on the perches or in the bottom of the cage. (00:22:15)

????

Continuity mistake: After the final attack they're all in the living room in the dark. As the camera pans from Melanie to Mitch the wick of the kerosene lamp faces it. In the next shot of Mitch alone the lamp has been rotated so that the wick still faces the camera. (01:45:15)

????

Continuity mistake: Before Melanie gets up to talk to Mitch on the phone her necklace has been rearranged between shots so that it now hangs lower around her neck. (00:45:05)

????

Continuity mistake: When we first see Melanie talking to her father the phone is pushed right up against the edge of the bar. The next time we see it's at a 45-degree angle to the side of the bar and no one has touched it. (01:15:45)

????

Continuity mistake: As Lydia walks up to Mr. Faucet's room, the hallway is dark except for the light coming through the door. The sunlight on the floor is much wider than the window of the door in front of her and there's no evidence of any light fixture above her or her hair would be lit up. (01:00:10)

????

Continuity mistake: As Melanie and Mitch go back into the house after Lydia calls him he grabs for the doorknob and we immediately here the sound of it turning as he walks through the other side of the door in the next shot. The problem is that they left out the screen door he would have had to open first before he could have entered the house. (01:34:55)

????

Continuity mistake: In the wide shot as Melanie brings the girl in the light blue dress to the house the front of the lawn chair facing the hill is angled to the right of the pole behind it. When Mitch carries the girl into the house, it's angled to the left of the pole. (00:53:00)

????

Continuity mistake: As Melanie walks over to the cashier in the pet shop the bird in the cage on the right with the greenish beak faces the other way between shots. (00:02:30)

????

Continuity mistake: As Annie leans up against the middle of the red mailbox she knocks the flag down. When we see her again her right arm is pushed up against the front of the mailbox and some amount of time, longer than the three seconds implied, has gone by as the shadow of the mailbox's handle moves between shots. (00:18:00)

????

Continuity mistake: When Mitch returns from the garage, the blood stain on Melanie's head is about an inch lower that it was before when Lydia put the bandage on it. (01:55:10)

????

Continuity mistake: So it can be seen better as Melanie looks out the window the stuff inside Mitch's barn is lit differently and moved between shots. (00:22:05 - 00:22:40)

????

Continuity mistake: Lydia's expression as she rests her head on Melanie's changes from a warm smile to a stern look between shots. (01:58:15)

????

Continuity mistake: The pink flowers behind Deke get rearranged between shots and no one touched them. The second time we see them, one flower in the center sticks out higher than the rest. (01:18:40 - 01:19:20)
