The Slumber Party Massacre

Continuity mistake: When the two boys are walking away from the telephone repair woman's van, one of the boys drops a book, and hands his friend two folders, and picks up his book. Suddenly in the next shot the friends hands are empty, and the two files are back in the other boys hands. (00:05:15)

Continuity mistake: After the pizza man is discovered dead, Kim puts the phone down on the desk before running into the living room. While Coach Jana waits on the line, it goes dead.

Continuity mistake: When Russ Thorn chases Linda down the corridor, she runs right to the end of the corridor, then heads down the last row of lockers, and Russ follows her (there is also no poster on the wall.) In the next shot of Russ running down this row of lockers, it's now apparant that it's not the end row; because there is no end wall, and now there is also a poster on the wall behind him. (00:13:00)

Continuity mistake: When Trish is speaking on the phone to Diane, she winds up a pair of toy wind-up shoes. In the first shot the toy shoes walk as far as the center of the desk, then run down. In the next shot, they are now right at the edge of the desk. (00:18:50)

Continuity mistake: In the shot where Russ Thorn watches as Kimberly and Jackie walk up the steps to Trish's porch, Kimberly's hands are empty. But when she enters the house, she holds up a case of beer in her right hand. (00:22:40)

Continuity mistake: When the Pizza Man falls through Trish's doorway, dead, between shots his position changes, and so does the position of his pizza box. Also, the greasy stain on the pizza box changes shape, and blood on the pizza box disappears too. (00:45:35)

Continuity mistake: When Russ Thorn grabs the telephone repair woman and drags her into the van, she drops her appointment book on the ground. In the next shot of the boys walking away from the van, the book that's supposed to be on the ground has disappeared. (00:05:15)

Continuity mistake: When Trish is putting some of her old toys away in a brown paper bag, she picks up her dog teddy. In the first shot the ear of the dog teddy is folded upwards, lying on it's head. In the reverse shot the ear hangs down, normally. (00:02:30)
