Continuity mistake: 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'. (00:41:40)
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: During the Top Gun scene, Derek steps on the table where Portia De Rossi and the other sorority elites are having lunch. You see her fetch from the table the Pepsi can, but then she holds it at a different height at the cut. (00:48:15)
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: When Sidney is doing her theatre performance, when she lifts up her red veil she wraps it around her shoulders twice between shots. (00:55:20)
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)
Factual error: The part of the play Sidney stars in begins with "All, behold the dreaded fate of Troy, that once stood proud and light upon the hills of Sparta." Please, what? There is a correlation between Sparta and Troy (the bride of the king of Sparta ran off with the prince of Troy, that was the casus belli), but phrased this way it does not make sense. (00:57:00)
Revealing mistake: When Randy, Gale, Dewey and Joel are sitting on a bench in the school grounds, Gale is smoking; but no smoke comes out of her mouth when she takes a drag. (00:58:35)
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)
Character mistake: Dewey says that it does not make sense that the killer, who at this point is characterized as a copycat of the Woodsboro team, attacked Sidney. Actually that's exactly what happened in the first Scream; after Casey and her boyfriend, Ghostface tried to kill Sidney. Dewey should know since he was the first responder on that call doing a puppet show at the door, and it's not only amazing that he wouldn't remember, but also that nobody corrects him and that they haven't run a timetable of the previous events at all. Of course in the end the pattern does not matter just as Dewey later says, but up to that point, the killer was following it to a T, so they are reaching the conclusion too early and against the evidence. (01:01:00)
Continuity mistake: When the cameraman says he's "one verb away from vacating these premises", there's a blonde with a green backpack walking left to right in the background. The same blonde appears two shots later behind Randy, who is further to the left than Joel. (01:01:45)
Other mistake: When the killer is stabbing Randy, you can see his reflection in the side mirrors. He stabs him many times. The same amount of blood is on the knife every time he lifts it up. (01:02:45)
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: 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: When Randy is jumpscared by the guy playing football (something the killer couldn't predict), in the aerial shot the football dude is standing on the crossroad that is fully in the shade instead of partially in the sun like before the cut. The two girls Randy harassed are also gone from their spot, which means in 5 seconds they packed their books and stuff they had laid out in front of them. (01:03:30)
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)
Deliberate mistake: It's a humorous twist that Randy's killing is covered up by some random guys passing by with a ghetto blaster, but there was dead silence when Randy was talking earlier; not being in frame does not block soundwaves. (01:05:15)
Continuity mistake: 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. (01:06:05)
Character mistake: The library of Windsor College is awful at cataloguing, since Sidney searches the "Social Sciences" section and her screen is full of books about Quantum Physics. (01:06:35)
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)
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.
