Continuity mistake: The house has only one gazebo and when the first bird swoops down at Cathy it flies over a different gazebo from the one we see later in the scene. The top is pointed and higher, and the correct one has a tree above almost touching it and shadows from the tree falling on it. (00:52:00)????
Continuity mistake: 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 mistake: As Lydia calls Fred Brinkmeyer about the chickens, notice the lamp and candle to the left of the phone. When Mitch uses this lamp later to tie the shutter closed it and the candlestick holder next to it are moved 90 degrees so that they are facing against the wall. (00:33:40)????
