Goofs made in Scream 3

	Incorrectly regarded as goofs: When Christine is running from the killer, she locks herself in a room. The killer makes a single thin linear hole in the door with his knife, but he then twists the knife, turning it into the circle we see later.
	Continuity: Kincaid's collar after putting on his jacket in the "What's your favorite scary movie?" scene
	Incorrectly regarded as goofs: In the "He who smells the gas" scene. The electricity is turned off yet the fax machine still works. A UPS is plainly visible next to the fax machine; unusual, but consistent.
	Audio/visual unsynchronised: Tyson's lips don't move when he is being chased down the stairs and says "oh you mother f*cker"
	Revealing mistakes: When the killer falls off the set and onto the bed below, the costume comes up and you can see a man's stomach.
	Incorrectly regarded as goofs: In Sidney's first scene, she walks up to the gate and punches in 1288 and then the * key and when she gets into the house she punches in 1288 and then the # key. Presumably "*" disarmed the alarm, and "#" re-armed it.
	Incorrectly regarded as goofs: In the final fight between Sidney and the killer, she stabs him in the back with an ice pick. Then she picks up his knife, but only to throw it out of reach. She can be seen removing the ice pick before stabbing him with it a second time.
	Continuity: When Sarah Darling is at Sunrise Studios while the office is empty, she is looking for the director of Stab 3, Roman Bridger. However when she looks into one of the office rooms, you can clearly hear her say Ronan, not Roman.
	Continuity: When Dewey first gets his gun out of the trailer, you can clearly see it's a Beretta 92-Compact in a black holster. But throughout the rest of the movie he uses a heavy duty snub (.44?) Revolver in a brown holster.
	Continuity: When Dewey fires the gun the first time (after they fall down the hill), he fires six times, empyting it. He doesn't reload, but still points it around, like it was loaded. Later on he fires the gun again (still no visible reload) three times and suddenly the gun is empty!
	Continuity: In the first killing scene the study which both Cotton and his girlfriend end up in has a white ceiling with a skylight. When Cotton is stabbed and looks up at his killer the ceiling is light orange with beams across it.
	Continuity: Roman Bridger's sideburns shorten and lengthen in the final scenes.
	Continuity: On the hot set of Sidney's room the table has its longest side flat against the wall with the bed. When Ghostface is thrown from the false door above the set, the table's rotated with its shortest edge against the wall with the bed. This was done so the bed was closer, so the killer could actually land on it.
	Continuity: When Sidney is struck down whilst trying to untie Dewey and Gale, she falls onto the middle of the rug. However she gets up from beside the sofa without rolling or moving from where she lands.
	Continuity: In the scene where the killer calls Sidney while she is at the police station, the word, "Nokia" is visible on the bottom of the phone. In the next scene it disappears, and then reappears in a later scene.
	Continuity: When Dewey unties Gale she lifts her and up and we see rope on her hand. In the next shot the rope is gone.
	Continuity: When Sydney from Stab 3 goes into the house to look at the fax machine there is no paper in the fax machine. Then the fax comes through on paper. After she reads the second fax there is paper visible in the fax machine behind her.
	Incorrectly regarded as goofs: When the killer chases Sidney through the set, she opens a door that leads to nowhere and climbs to the side of the set out of view of the camera. The killer would have known the door goes to nowhere; that wouldn't stop him/her from opening it, and the fall was because Sidney pulled the killer's shirt.
	Continuity: When Sidney jumps out of the window in the Sunrise Studios, and Dewey comes to her, there's a point where she is looking down, and the camera angle changes to show her looking right at Dewey.
	Continuity: When Gale reaches for the voice changer, she has blood on the top of her hand. When she puts the voice changer to her mouth, there is no blood.
	Factual errors: When Cotton is on two lines at the beginning of the film, he puts his portable phone on hold. The brand of cell phone he is using doesn't have a "hold" feature.
	Continuity: When Sidney goes through the door that leads to nowhere, she holds on and grips the wall frame. She could not have closed the door from her location because it was almost fully open and out of reach (though some viewers have claimed she could have used her foot).
	Incorrectly regarded as goofs: Jennifer says she is next to die in the script of Stab 3, which Dewey confirms. However, when Jennifer is about to be murdered, she says "You can't kill me, i'm the killer in Stab 3." She's saying anything to get the killer to stop; in addition, there were three versions of the script, and she might have been the killer in one of them.
	Audio/visual unsynchronised: Every time the killer calls someone on their cell phone and hangs up, you hear a dial tone. Cell phones don't have dial tones.
	Continuity: Christine gets out of the shower and steps on the towel, but when she gets dressed and starts to walk down the hallway, her feet are still soaking wet.
