The Birds (1963) - 121 mistakes

Continuity: When Tippi Hedren is having her head wound cleaned in the restaurant, Rod Taylor is wiping her blood off with a tissue but it does not actually come off; in the next shot, however, there is clearly no blood on her head.

Continuity: After Melanie has been bandaged up after her attack, she sits up on the sofa, and you can see two large bloody scratches on her left cheek. These scratches disappear when Mitch and Lydia walk Melanie outside to the car.

Continuity: When Lydia brings out Cathy's birthday cake, in a wide shot the icing is white, then in a closeup the icing is a pink colour.

Revealing: The birds that attack the schoolchildren have no shadows.

Continuity: The tall structure on the hill behind the swing set has a lot of clouds around it. When we see it seconds later the sky is clear.

Continuity: Early in the movie Melanie makes a right turn as she goes up to Annie's house and we see a white post on the school side of the street and a stop sign on the opposite side. Now as she drives up to the school to check on Cathy we see the exact same spot and there's no stop sign.

Continuity: Before Lydia walks into Mr. Faucet's room she looks to her left and her face is entirely illuminated by the light coming from his room. In the next shot as she walks in only the left side of her face is illuminated.

Visible crew/equipment: In a scene where Melanie, Mitch and Cathy are walking to the building on the hill along side Melanie's car, you can see the camera move in the reflection on the side of the car.

Continuity: As Melanie opens the door to the bedroom there is no light except her flashlight but you can see two distinct reflections in the door knob, one of the flashlight and one of the studio light behind her.

Continuity: As Annie opens the door and finds the dead bird on the floor, the background across the street changes from of a very dark house with two lights on to a moonlit road between shots.

Audio problem: When Annie says, "Did you drive up from San Francisco by the coast road?" her lips are mouthing something different.

Continuity: As the school children are running down the hill a white fence appears between shots in the background on the right of the screen.

Continuity: When Melanie gets up and looks at the birds massed on the monkey bars the area behind her is a tree and a field. This background changes entirely when she and Mitch walk up to find Annie's body and there is what looks like a junk yard with a valley behind it.

Continuity: As everyone runs out of the restaurant, the bushes on the left of the building that were there before are gone.

Continuity: Melanie walks out from behind the desk and goes into the hallway to get the nightgown to show Annie. No one ever flicked a light switch, but the hallway is now very well lit up.

Continuity: After finding Mr. Faucet's body, Lydia gets back in her truck through the passenger side door. Notice that the window is rolled up and the side vent window is shut tight. Seconds later we see her inside the truck with the window rolled down and the vent window tilted open.

Continuity: A blond boy in a light brown shirt is attacked by a crow and goes from having no blood on his neck to having a lot of blood smeared on his neck between shots.

Continuity: As Mitch walks up to the garage door all the birds on the ground that are near him run away and there's nothing to his right except a garbage pail. Then just before he walks through the door two birds appear pecking at his feet.

Continuity: When Lydia says to Melanie, "Do you think Cathy's alright at the school?" the two pictures hanging above her head disappear the next time we see her.

Audio problem: As Annie says to the students, "All right children now quiet," her lips do not match what she says. This continues before she says, "Miss Daniels" and her lips move and nothing comes out.
