Audio problem: When Sidney comes running to the house and she sees Dewey come out with the knife in his back she screams "Dewey!" but her mouth says "no!"

Revealing: As Drew Barrymore is running from the killer outside he stabs her.  If you look closely it is very easy to tell it is a rubber knife, because you see it bend off of her.

Continuity: When Ghostface is trying to kill Tatum in the garage, she tries to go through the doggie door. From the outside shot, she is out of the door from her arms and up. From the inside shot, she is out of the door from her hips and up.

Deliberate "mistake": When Randy is explaining the "rules" and he is standing beside the television the batteries fall out of the remote yet he still manages to change the TV over.

Audio problem: When Gale is talking to Kenny the cameraman before she goes off to investigate the abandoned car with Dewey her face is in a close up. She can be clearly heard uttering the forbidden phrase "I'll be right back." However her mouth can clearly be seen saying "keep watching."

Continuity: After Sidney has been attacked and is in her room.  Billy climbs through the open window. It is completely open. After he drops his mobile phone, the window is only half open.

Continuity: As Gale is talking to Dewey outside the school, when she is trying to get information from him about the killings, Dewey takes his sunglasses off and hangs them on his shirt. In the following scene they hang two different ways every time the camera cuts to him.

Continuity: When Henry Winkler opens his door to look for the "kids" that keep knocking, you can see red writing on the wall opposite. When he comes back in from checking out the hallways, that writing is gone.

Revealing: When the killer surprises Syd after she's come in from outside and locked the door, he tries to stab her with his left hand, misses, and hits the door right next to the chain in closeup. In wide shot (very quick shot) when Syd legs it, look at the killer and you can see he's holding a very badly bent knife in his right hand, nowhere near the chain. Submitted by Jon Sandys

Continuity: After the curfew has taken effect, Dewey and his Sergeant are standing on a sidewalk in town.  The Sergeant is smoking a cigarette.  In one scene, the cigarette is almost gone, then he drops it and he steps on it, but it's almost an entire cigarette.

Continuity: At the very end, when Sid finds out who the killers are, they are all standing in the kitchen. When Billy and Stu stab each other take a look at the blood stain on the left side of Stu's jumper. It starts around his shoulder and vertically goes down towards his waist. When Sid is fighting him in the lounge she gets up and goes behind the TV. In the shot looking straight down on Stu from a birds eye view, notice the blood stain is now horizontally across his stomach. You'll have to look closely for this one.

Revealing: When the killer first stabs Casey, whilst chasing her outside, you can see that as the killer grabs her, some of Drew Barrymore's real hair fall out from under her wig. Submitted by Hamster

Continuity: When the cameraman is watching the 30 second delay footage and the ghost face is about to kill Randy who is on the sofa, he walks into the room in a different way on the delayed footage to on the actual film footage.

Continuity: Sidney is on the roof trying to escape from the killer and she falls off. When she gets up she sees the dead body of Tatum in the cat door and her left arm must be behind her because you can't see it but this isn't what happened when you saw her die. Her left arm was inside the garage and was beside her. Unless if fell off, it should be next to her body.

Factual error: After Gale talks to Sidney and Sidney seems doubtful of Cotton Weary's guilt, Kenny the Cameraman says to Gale, "Do you wanna go live?". Gale is an anchor/reporter for a tabloid-like show called "Top Story" (Sort of like "Current Affair", "Inside Edition", or "Hard Copy"). She does not work for CBS News or NBC News, etc. She does not have the power to "go live" and interrupt regular television programming.

Continuity: When the killer sneaks up on Randy, Randy is lying back against the sofa. When Ghostface raises the knife Randy is lying back, relaxed with a tired look on his face. On the delayed footage when the killer raises the knife, Randy leans forward and is practically on the edge of the seat, his mouth and eyes wide open.
