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)????
Continuity mistake: Just before the lights blowout Mitch comes back into living room and there is a red ottoman to the right of the green chair that Lydia and Cathy are sitting in. A few moments before, all three of them just walked through that spot when they were hiding by the bookcase and it wasn't there. (01:44:05)????
Continuity mistake: There's a fixture with a wire hanging down from it in the front left corner of the restaurant. When they built the interiors for this scene they forgot to put it there and when Melanie opens the phone booth door trying to get out the wire hanging from the bottom of the roof of the restaurant is missing. In the close-up as Melanie tries to get out the cord that we saw previously sticking out has been tucked back in towards the phone for this shot. (00:26:25 - 01:26:45)????
Continuity mistake: As Melanie and Mitch walk past the side of the restaurant look closely at the second and third windows from the right. Now we can see right into the place through these but after they walk into the restaurant look behind the bar all three windows have drawn blinds. (00:26:25)????
