Continuity mistake: When the orange car explodes there is much more gas around especially under the guy's feet than in the previous shot. (01:25:30)

????

Continuity mistake: As Lydia looks at Melanie and Mitch walking down the hill, the large piece of molding in the corner between the door and window disappears between shots. (00:51:50)

????

Continuity mistake: As Melanie approaches the cashier, there are several birds up high in the cage directly behind the cash register that aren't there in the next shot. (00:02:30)

????

Audio problem: When Mitch turns on Melanie's car radio he turns the tuner knob and stops on the station that he eventually tunes in, goes a little bit forward and then back again to the same spot. The over-dub is not correct as we would have heard the announcer speaking the first time he landed on the station. (01:53:55)

????

Continuity mistake: When the uptight mom starts talking, Melanie sheds a very long tear under her right eye that appears out of nowhere between shots. (01:28:35)

????

Continuity mistake: After Mitch finished pouring out the drinks for Melanie and himself there was still a little bit left in the bottle. He never pours out any more but as they get to the bottom of the hill when they throw away their glasses the bottle is empty. (00:51:35)

????

Continuity mistake: After rescuing her Mitch picks Melanie up and carries her down the stairs. At first her right leg is sticking straight out and her left is bent but in the next shot both her legs are bent. (01:49:50)

????

Continuity mistake: Melanie starts to blow the horn of the cream colored station wagon and we see her left hand go from flailing around to being firmly on the steering wheel between shots.

????

Continuity mistake: As Lydia sits in her bed and says to Melanie, "I don't think I can bear to be left alone" watch the picture behind the door to the right of Melanie. The shadow of the door on the picture changes from the right to left between shots. (01:07:00)

????

Continuity mistake: 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. (01:00:55)

????

Revealing mistake: As Mitch and Melanie look at the birds perching on the Bodega Bay School they're all fake. The only two that move are to the right of the wire and they're attached so they swivel forward and backward in the wind. (01:29:40)

????

Continuity mistake: After the birds break the window, Mitch tries to close the shutter and they peck at his left hand bloodying it up. In the next shot as he finally gets the shutter closed there's no blood on his hands. After this he ties the window shut with the cord from the lamp and the blood on his hands is back again. (01:42:05)

????

Continuity mistake: We see the back of Mitch's coat as he reaches for the doorknob of the restaurant. It's wetter in the next shot as he brings Melanie back into the restaurant. (01:27:45)

????

Revealing mistake: The wing of a fake bird, unable to fly straight, swoops down and hits Melanie in the head as she runs to the phone booth. (01:26:10)

????

Continuity mistake: Mitch puts the glass of brandy up to Melanie's lips and we see the brandy touch her upper lip and slosh around but then as he pulls it back there's not a trace of liquid on her lips. (01:50:45)

????

Continuity mistake: On top of the hill Melanie spills a drop of her drink on her green skirt. It's on her right leg six inches below the bottom of her jacket. The action doesn't stop, but three minutes later the stain is gone. (00:48:40 - 00:51:25)

????

Continuity mistake: Mr. Faucet's tiny windows are not wide enough to let in the amount of sunlight that's shining on him from left to right on such an overcast day. (01:00:30)

????

Continuity mistake: As Mitch crouches down near Annie's body he turns to look at Melanie and you can see a large wet stain on the porch. It's there until he sees Cathy in the window, then as he runs to the front door it disappears. (01:30:30)

????

Continuity mistake: When Melanie yells, "Where's Cathy?" Mitch looks up to see her in the window and she is moving the right curtain with her hand as she cries. In the next shot as Mitch runs to the door the curtain is not moving. (01:30:40)

????

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)
