Revealing mistake: A quick mistake happens when Brenda and the girl crawling out of the TV get in a fight. Brenda throws the punch, the other girl falls over, and for a quick second her dress flies up too far and you can see where the makeup (that makes her look dead) on her legs end and you can see her real thigh.

Trivia: When Cindy and the rapper guy are fighting the Ring girl, the president walks in and says, "I just want to wish you both good luck. We're all counting on you." and then he walks out. This is a joke from "Airplane" where Leslie Nielsen is the doctor. He says the same line. The reason it is in the movie Scary Movie 3 is because the director of Airplane also directed this.
George: Sue's teacher, Brenda. She's... She's dead.
Tom: Oh. I better tell her.
George: No, no, no. I can do it. Sue?
George: You know your teacher, Miss Brenda?
George: She's dead!
George: Gone forever! Died a horrible, painful death! Gone, gone, gone, just like your dog!
Sue: My dog's dead?
George: I just ran him over with the car when I drove in! Everyone you love around you is dying!
