Continuity mistake: The position of Melanie's car has changed from when she first parked it in front of Annie's house. At first the rear wheels are adjacent to the steps, but later they've been moved back slightly so the front seat is adjacent to the steps for Annie to lean in when they speak. (00:18:10)????
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)????
