Continuity mistake: Outside the police station, Dewey stops because Gale is being sympathetic with her 'feel bad' speech. His hand is on the corner of the public phone in one shot, to the left in a different spot in the next shot. (01:14:35)
Continuity mistake: Sidney says all of a sudden "Oh my God" because, as we then learn, she spotted Dewey. Jerry O'Connell's backpack switches shoulder from right to left. (00:22:15)
Continuity mistake: At the police station, Cotton sarcastically says "Ok then, book me." Look at the door the chief of police is walking towards, which has his name on. In close-up there is a string touching the C of "Captain", that is missing in the wide angle. (01:10:10)
Continuity mistake: When Cotton presses Sid against the library wall acting all creepy, Neve Campbell's hair is arranged differently on her forehead, sometimes with a stray wisp, sometimes not. (01:08:05)
Continuity mistake: Gale dispossesses a girl of her phone and starts arguing with the person on the other side. The girl has a friend to the left of the screen who just before Gale throws the phone back raises his hand. In the next shot his hand is on his knee. (01:03:45)
Continuity mistake: The killer asks Randy what's his favourite scary movie; there's a POV of Randy that spots two girls sitting on the lawn. A tree behind them casts a big shadow in their direction, which changes orientation entirely in the shot when he touches the one with the phone. (01:03:10)
Continuity mistake: Gale, Dewey and Randy stand to go look for the killer who just phoned them. Throughout the earlier part of the scene the background behind David Arquette's close-ups showed the house and ground with a lot of sun filtering from the foliage, and the background behind Jamie Kennedy was much darker, but now you can see even the 'Arquette background' being dusky. (01:02:50)
Continuity mistake: Nobody moves after taking their masks off and looking at Sidney helpless on the floor. There's a close-up on two guys who take off their mask, one is a robust guy with short hair who removes a bearded old man mask. When Sidney flees, she passes by him, who is not standing close to the other guy anymore. (00:59:25)
Continuity mistake: Sid is talking to Gus, the drama teacher who is adamant that it's a good idea to put her in a scene with half a dozen masked people play-stabbing her. She says "I'm a fighter", and behind her there are a couple girls making their way through the seats and a guy carrying a drink from the other side. Gus swiftly replies "I didn't hear that", and the camera cuts back to Sid, showing the people who were in transit a split second before already perfectly seated. (00:55:35)
Continuity mistake: Derek gives Sidney his necklace and the two kiss. He puts his hand on her shoulder, then in the same shot the hand slides down, lower than the elbow. Wide shot, and he's still holding her shoulder. (00:50:00)
Continuity mistake: After the meeting with the police chief, Gale asks Dewey to let her help out. During their conversation, the natural light changes wildly depending on the angle; just look at the collar of David Arquette's jacket. (00:45:50)
Continuity mistake: Trying to kill Sidney, Ghostface plunges into the front door of Delta Lambda a knife that is soaked in blood - even if they already cleaned ACICI's. Derek on the other side of the door looks at a knife that is mostly clean except a couple of tiny specks by the blade, and Ghostface pulls the knife back again bloodstained. (00:39:40)
Continuity mistake: When ACICI apologizes for calling the guy "Ted" and says "I thought you were someone else" she is suddenly touching her left cheek between shots. (00:30:00)
Continuity mistake: Cici wrongly assumes his ex is at the phone and says his name; "Ted?" The blue pillow she's leaning her right part of the body agains changes position between shots. (00:29:35)
Continuity mistake: Gale massages her chin after she's hit, but does it alternatively with her thumb tucked under the chin or outwards, depending on the camera angle. (00:25:45)
Continuity mistake: Both when Gale speaks into the microphone saying "Tell us everything that's happened", and when she wags her finger at her motioning her not to punch her, her hand is at heights inconsistent between shots. (00:25:15)
Continuity mistake: Sidney and Dewey begin their chat. In the wide shot, you can see that a girl is passing by the gazebo, behind it. She does it again in the next closer angle on the two talking, starting from way back. (00:22:50)
Continuity mistake: When Gale tells Debbie off giving her a nasty 'quote', the sun shines on Laurie Metcalf's sleeve in the angle where she says "Great!" and does not in the ones before and after. She is left standing in dismay, and you can see her in background with the sun casting another entirely different shadow even if she didn't move. (00:20:05)
Continuity mistake: Debbie Salt introduces herself to Gale Weathers and asks her a question that Gale does not like, so much that she puts her hand on Joel's camera and points it away, downwards. At the cut though Joel's camera is back up. (00:20:00)
Continuity mistake: When Mickey mentions Godfather Part II, there are reaction shots on the other students who have to agree on that statement, but their positions are inconsistent between shots (for instance the girl with the blue shirt has both hands joined at first, then at distance, the girls on the background to her right are leaning towards each other at first, then not, etc). (00:17:00)
Chosen answer: In real life, they'd have known there was a phone call involved. They would have known her boyfriend was killed. They could have easily pieced together that the killers played a cat and mouse game with the Drew Barrymore character. But that doesn't account for all the details. Anything else would be speculation. My speculation: Maybe Billy Loomis kept a diary.
