Continuity: In the beginning where Jada Pinkett Smith is stabbed in the back, you see a white girl to her right look down at her arm as Jada's blood lands on her. If you watch the background closely as Jad is dying and stumbling around, the same girl is still looking around, as if it just happened.

Other: It is highly unlikely that the murderer knew Omar Epps' character was going to put his ear to the stall when he heard music. It is even more unlikely that the murderer is going to get Omar Epps' character on the first stab. But it makes for good cinema.

Continuity: During the last stabbing of Maureen Evans, the killer puts his right arm around her and stabs her with his left; but from the back view, his left arm is around her, and he is stabbing her with his right.

Revealing: In the scene where Randy, Gail, Dewey and Joel are sitting on a bench in the school grounds, Gail is smoking; but no smoke comes out of her mouth when she takes a drag, nor does the cigarette have any smoke coming off it.

Continuity: In the scene where Dewey enters the sound studio where Gale is, when he is sliding down the glass after being stabbed we see Gale's reaction from behind. The Gale shot you see ghostface looking down holding Dewey yet 3 seconds later ghostface is standing looking at Gale and Dewey seems to have dissapeared when he is supposed to still be against the glass.

Continuity: Shortly after the scene in which the killer pulls Randy into the van, Gale and Dewey run to the van and see the blood. Right before they open the door, there is a camera shot from inside the van through the window. You can see that the window is not broken: it is obvious that there is some sort of white fabric over it.

Continuity: When the killer attacks Sidney and the bodyguards in the car, he smashes through the driver's side window, leaving some of the glass still around the edges. When the killer drives off, these fragments have dissapeared and the window is totally gone.

Continuity: When Sydney is rehearsing her play she pulls the red shawl around her shoulders twice in different shots.

Continuity: After the accident - when the car is seen from behind - you can't see the killer (it's before Sid crawls over him).

Continuity: When the girl - during the Stab film - touches her boyfriend's jacket and gets blood on her hands - in the second clip there is much more blood on her hands than in the first clip.

Continuity: During the scene where Gale is underlining the names with the connection to Woodsboro on the board, she underlines 'Stevens' with the camera behind her and the line reaches across the whole name. In the next shot, the underline is just reaching up to the 'n'.

Continuity: When Gale is in the theatre and gets shot and falls from the stage, she has blood stain on her left breast (above the place where the shot wound appears). Yet later, when she climbs back to the stage, she has no blood stain, only the shot wound.

Continuity: When Phil Stevens is in the bathroom at the beginning of the movie, his watch switches from his left hand to his right hand.

Continuity: When Debbie Salt is holding the knife on Sydney, the knife changes positions from time to time.

Continuity: In the beginning of the movie, Jada Pinkett orders a popcorn and a small Pepsi from the concession stand. As she walks back in to the theatre she clearly has a jumbo sized large.

Continuity: When Dewey and Gail are in the classroom and as they are making out, when they realise that they are being filmed, Dewey has one side of his jacket off below his shoulder and in the other camera angle it shows that he has it perfectly on.

Audio problem: When Gail and Dewy are watching the tape of their conversation in the park, the sound of their conversation is way too clear taking into account their distance from the camera and the microphone, and there is no ambient noise at all.

Factual error: During the scene in which they are all arguing whether or not film sequels are better than the original or not, someone says Sigourney Weaver's classic line from the movie Aliens: "Get away from her you bitch", and Randy makes a smart comeback and tries to correct him by saying "I think the correct line was 'stay away from her you bitch'. This is a film class, right?" Wrong - the first guy was right. This line is truly unconvincing for the Randy character, being a big movie buff and all.

Continuity: When Dewey is being stabbed in front of Gail in the soundproof room, there is already blood on his his shirt. But you have to look very closely.

Revealing: At the start when Phil Stephens is being stabbed, when the killer draws back the knife you can see there is already blood on the knife. Its only there for a second so you have to look carefully.
