Continuity: As Melanie holds out her right hand to shield the boy in the white jacket we get a really good close-up of his neck. It was bleeding three shots ago as a crow was attacking him but now it's not.

Continuity: As Annie and Melanie speak about how they met Mitch, watch the shadow move down the front door. A considerable amount of time has gone by between shots.

Visible crew/equipment: In the close-up of the orange car there's a perfect shot of the cameraman in the bumper as the gas hits the tire.

Deliberate "mistake": When Melanie first walks into the classroom she sees five rows of students. Later when the students are about to leave there are only four rows of students, now ending with the boy in the plaid shirt (closest to the camera), in the front. The row on the left has been removed so the camera can pan from left to right in the side shot.

Continuity: After Mitch ties the shutter closed both sides of the window look identical with each shudder being seen through the window, but as he walks back into the living room just before the lights go out the left shutter is the same and the right shutter is black.

Continuity: As Lydia looks through the window of Mr. Faucet's kitchen there is a distinct pattern on the wall to her left. As she comes through the door the pattern on the wall is different and she's in a different room.

Continuity: The lamp over the dining room table, when Melanie brings Cathy back from the bathroom, is not this same lamp that was there as they were listening to the television report. Before it had a glass bottom and now the entire bottom is made of metal.

Continuity: As Lydia carries the birthday cake out from the house the position of the vine growing on the pole on the right jumps from right to left between shots.

Continuity: As Melanie runs to Annie in the classroom and says, "Close that door quickly," all the children's jackets and sweaters and everything on the bench below changes between shots.

Continuity: After Mitch rescues Melanie from the phone booth he places her to the left of the front door of the restaurant as he reaches to open it. In the next shot their positions change and she is in front of the door going into restaurant.

Continuity: As Melanie talks about renting the apartment Annie's hair changes slightly between shots. Two little pieces of hair stick out right by her left ear that weren't there in the previous shot when she opens the door. Annie's hair changes in other consecutive shots throughout the film.

Continuity: As they go up to the restaurant to get help Melanie says, "I had a booster before I went abroad last May" and the background changes abruptly between shots.

Continuity: When we first see the table with the food on it the sandwiches in the middle are piled up in interlocking stacks of three with one more pile of three or four sandwiches rising in the center. When we see the sandwiches again up close as Mitch brings the little girl into the house, they are neatly stacked above each other though not interlocking as before and the middle pile is not there.

Audio problem: Before Melanie starts off across the bay we hear the boat keeper start the boat's engine. But this is only an over-dub, the engine's not really running as there's no turbulence behind the boat like in the next two shots.

Continuity: After Melanie hangs up the phone she sits and ponders whether to go to Cathy's party, on the desk to the left of the phone is the cigarette lighter that Annie left there before after she lit her cigarette. Next to it is a pack of cigarettes that she didn't leave there before. If you look closely earlier as she takes the cigarette out of the pack in the left pocket of her nightgown the lighter is in her right hand, the cigarette in her left and the pack stays in her pocket.

Continuity: As Melanie stands in front of the pet shop and watches the birds flying, more time passes than the two seconds implied. The kittens in the right window go from playing to sleeping between shots and a grey kitten appears in the window that wasn't there before.

Plot hole: When Jessica Tandy walks into Mr. Faucet's house everything is in perfect shape except a couple of broken cups, and there's not a dead bird in sight.

Visible crew/equipment: When Cathy brings a pot of coffee into the dining room, you can see several bright studio lights reflected in it throughout this scene, and you can also briefly see the reflection of someone's arm moving about on it.

Continuity: When Melanie is walking up to the counter in the bird shop she has a black purse in her hands. In one shot she is walking to the counter with her purse in her hands, but in the following shot, her purse is laying on the counter and is now taking off her gloves.

Continuity: At the children's party, when the birds attack, you can see a child roll under the table with the cake and other party snacks on it. The birthday cake swaps ends with the bowl of drink a few shots later, with nobody re-arranging it.
