About one hour into the film, Brooke addresses a letter to Dr. Norris. In close-up the envelope is small (letter size) and the address is written almost to the right edge. However in the next wider shot, the envelope is larger (business size) and the address is more centered.
When Eric and Brooke are driving in the country from their city honeymoon hotel, they are in a dark car and pass an open area on the right. There is an abrupt edit as can be noted in the changed shadows on the right, before the car that is following them closely can be seen.
After Dr. Norris tells Brooke about her husband at her house, he leaves and she stays by the front door. The image is frozen for two to three seconds as Brooke does a voiceover narration.
