Corrected entry: When the girls are standing in the doorway of Liz's bedroom, talking to Fern (she had stopped by to drop off Liz's homework assignments), Courtney thrusts out her arm, stopping Julie as she steps forward. Here, her strap falls down to her shoulder. The shot switches to Fren, then back to Julie, her strap is back on her shoulder, as if it had never moved.
Corrected entry: When Julie is waiting to get on the bus and Zach offers her a ride, she is holding a book. When he drops her off at her house and she gets out of the car, she doesn't have a book with her.
Corrected entry: In the scene where Julie, Marcie, and Courtney are sitting outside talking about what to do with Liz's body, Julie takes her sunglasses off of her face and holds them in her hand. In the next shot, about two seconds later, the sunglasses are sitting on her head, with the earpieces tucked into her hair.
Corrected entry: When Fern and the girls are first talking in Liz's house you get a glimpse of Liz's body. Later in the movie, when the police are coming to investigate the murder the body is in a totally different position.
