Continuity mistake: In the wide shot of the party scene as everyone is running into the house a girl in a bright red sweater and white skirt pulls her mother in the blue dress by the hand. In the next shot they've changed positions and are together with the mother's arm around the girl's back. (00:53:00)????
Continuity mistake: As Melanie walks around with her flashlight she goes into the kitchen and looks at the lovebirds. This cage has 11 rungs on the side and is not the same one that she walked into the house with when she brought the lovebirds up from San Francisco, which had 19 rungs. (01:46:15)????
Continuity mistake: In the shot of Mitch holding the log just before he runs to the window behind the desk, the brown reclining chair that sits by the fireplace has been moved for the camera. We see it there in the scene when Lydia says, "Did you get the windows in the attic Mitch?" and earlier in the movie when Melanie brings the lovebirds in. (01:41:20)????
Continuity mistake: As she's fighting off of the bird attack in the bedroom Melanie looks like she is turning off the light switch on her right. There's no power in the house but the light on her does go out. It's not a reflection from the flashlight, which is aiming at the ceiling before the light goes out. (01:48:30)????
Continuity mistake: As Mitch checks the window behind the TV set we see the picture of father above the piano there's no shadow on it. Later as they all sit waiting for the bird attack even though no one's turned any lights on or off a dark shadow appears above the middle of the picture. (01:37:05 - 01:40:45)????
