Continuity: The amount of blood on Kate's face decreases between the time she is attacked and discovered. The pattern changes from shot to shot as well.

Continuity: As Liz describes her nightmare to Dr. Elliott, she walks across his office gesturing with her hand to aid the description. The camera angle changes, and her hand is now in her pocket.

Deliberate "mistake": Has there ever been a more obvious body double than the one used for Angie Dickinson in the shower scene? Not only does the top of every shot stop right at the collarbones, she is much taller than Dickinson, she has a much deeper tan and (of course) her breasts are much, much bigger.

Continuity: While Dr. Elliot is being interviewed, there is a yellow piece of paper stuck to the window behind him. After Peter leaves and Detective Marino reenters the office, the paper has moved about a foot higher up.

Continuity: Kate throws her other glove down onto the steps of the museum. When she walks down the steps towards the cab, the glove is not visible behind her. It should be on the square of stone that is above her left shoulder.

Continuity: When Kate drops her glove, it lands with the fingers pointing towards the wall. When the man picks it up it has rotated by 90 degrees.

Continuity: Kate writes a note but then scribbles it out and pushes it to one side, next to the magazine on the table. In the next shot, she starts writing another note, and the first one has completely vanished.

Continuity: At the museum, Kate writes "Nuts" into her diary. A few seconds later she writes "Pick up turkey." and in the intervening period the word "Mints" has appeared below "Nuts".

Continuity: When Liz is talking to the police and Dr. Elliott's psychiatrist after Dr. Elliott is shot, she gestures many times, showing that her hands are perfectly fine. How is this possible when Dr. Elliott slashed them? Even if this conversation takes place much later, she should still have a small bandage or signs of stitches.
