Continuity mistake: At the end of the movie, after Dewey asks Gale to marry him, she lays one on Dewey. She leans to the left of his face when they start kissing, and at a cut away long shot she suddenly is kissing on the right... then the close up is back at the left. (01:44:30)
Continuity mistake: When the actors, Gale and Dewey are hanging around in Jennifer's house, they realise a fax is coming through. When Jennifer first approaches the machine, notice that there is actually no paper in the machine. A few shots later, the paper supply has suddenly been replenished. (00:44:20)
Continuity mistake: When Sidney is talking to the killer in the police station, her phone has a "Nokia" sticker on the bottom of it. Later in the scene, it's gone. (01:29:15)
Continuity mistake: In Scream 2 Dewey walks with a limp and his right arm curled up. In Scream 3 he walks with a limp and his left arm curled up.
Continuity mistake: In the opening scene Christine is completely dry when she steps out of the shower. (00:03:05)
Continuity mistake: The first time Gale goes to Jennifer's house, if you look when Dewy gets out of his car the window is down. Look quickly to see when Dewy closes the door the window is up. (00:30:40)
Suggested correction: I really can't see it. He gets out of the car and closes the (car) door in the same shot so it's not that. He gets out of the car (the window is indeed down) and then goes to the front door, but he does not close that door, and from there you can't see the driver side window anyway. Am I missing something?
Continuity mistake: When the bodyguard finds Gale eavesdropping on Dewey and Jennifer, they soon confront each other and Tom is sitting in a chair with his left hand on the arm rest. In the next shot Tom is smoking a half finished cigarette with his left hand, but he had no time to change the hand with the cigarette in it between shots. (00:40:00)
Continuity mistake: The second time Gale shows up at Jennifer's driveway (right before the place blows up), one can clearly hear her turn off the lights and remove the keys from her car. Yet, when she opens the door, the car still makes that beeping noise that happens when you leave your headlights on or leave your ignition key in the ignition. (00:37:10)
Continuity mistake: The ice pick remains free of blood even when Sid has stabbed the killer with it twice.
Continuity mistake: Gale's bangs change lengths throughout the film.
Continuity mistake: When Sarah tries to fix Roman's statue's head, her hair is over her face, when she goes to answer the phone her hair is pulled back behind her ear. (00:23:20)
Continuity mistake: In the beginning when the killer is trying to kill Cotton, he pulls a book case on the killer, but if you look carefully you see that the killer slides to the side, despite the fact that the book case is meant to have hit him. (00:08:55)
Continuity mistake: Before Sidney pulls the killer out of the door on the house set, we see the bedside table is lengthwise against the wall. As the killer falls towards the bed it's turns 90 degrees, so the bed is a bit closer to the door. (01:05:45)
Revealing mistake: Stunt double is visible when Dewey falls down the steps at Milton's house. (01:27:00)
Character mistake: When Jenny McCarthy goes to the office to meet the director. She's calling out his name to see if he's there & calls " Roman.......Ronin.......Roman". (00:23:15)
Continuity mistake: In the scene where Jennifer gets killed and falls through the mirror look at Dewey's hair it's all messed up, but in the scene right after that when Dewey and Gale are looking for Tyson his hair's all combed back again.
Audio problem: When the killer has on his mask and you hear "the voice," he does not need to use the changer to mask his voice. But we see that it is just a plain old Halloween mask.
Continuity mistake: At the part where Sidney is on the set of her house and the killer is chasing her up the stairs, she runs right by the plants, but in the next take she is right next to the plants just about to throw one. (01:05:25)
Suggested correction: Sorry but no; she runs by -some - plants, and in the next take she is right next -other - plants, which she throws at the killer, who is just passing by the -first - plants. You can see both plants at the same time on screen if you are watching a version in the proper format.
Continuity mistake: Dewey rolls down a hill after shooting at the killer. The cut on his forehead changes shape from circular to two parallel lines then to a straight line and a waved one.
Other mistake: When Sidney is on the set with her mother's covered body, it rises up and reaches for her, speaking in her mom's voice. Sidney calls out for Dewey before climbing out of the window. However, when she's grabbed, she yells out her own name: Sidney.
Suggested correction: No, listen to the voice; it's Fake Ghost Mom that yells "Sidney" as part of her Scooby spooky act; Neve Campbell just cries out "No."
