Other mistake: On the back cover of Scream 3 in the Scream trilogy on DVD, the town of the original killings is referred to as Greensboro twice. The correct name of the town is Woodsboro, of course.
Suggested correction: I'm not "correcting" this per se, but I'm wondering if there should be either a separate type of mistake for things like DVD/Blu-Ray cases or posters (Ex. "Multimedia and Marketing Mistakes" or something like that), or if these things would be better classified as trivia? Especially since it's not something everyone can necessarily observe watching the movie itself. (Ex. My Blu-Ray and 4K releases don't have this mistake.) If not, feel free to downvote/delete this. I've just seen a few of these mistakes over the years here, and it always seems a little off to me since it's not something wrong with the film itself.
I agree these aren't valid movie mistake if the studio wasn't involved in the mistake. It could be trivia if only certain home releases had them. These mistakes are like when episodes are aired out of order creating continuity issues,, streaming services make changes, or closed captioning (not subtitles) gets something wrong. It can't be considered a mistake of the film or TV series.
It's tricky - largely, if I'm honest, because adding new types to the site is incredibly fiddly. :-) There's also room for endless debate about what's a "mistake", whether it's about assigning specific blame or just looking for interesting stuff. Likewise things that can only be seen in slow motion, which arguably warrant a category to themselves because there are plenty of them, but then the "mistakes" section gets cluttered. Becomes a user interface issue as much as anything! Will think.
Continuity mistake: When Christine gets out of the shower at Cotton's apartment she has dried off, stood and walked on the carpet, and put on a nightie. When the stereo starts blasting and she walks down the hardwood floored hallway her feet leave very wet footprints which she slips in later when the killer chases her back up the hallway. (00:03:40)
Continuity mistake: When Sidney is first going into the house for the end of the movie it is clear that she is not wearing the vest underneath her clothes and as she is walking around or when she is rolling on the ground fighting with her half brother you see her bellybutton but then she has the vest on and it goes over the belly button.
Continuity mistake: When Sidney is fighting the killer, when ever a big stunt comes up, the killer's hair gets lighter.
Visible crew/equipment: When the killer throws Tyson off of the balcony, you can see the black fabric of the landing mat fly up after the stunt double lands on it. (01:20:20)
Continuity mistake: When Jennifer is in behind the mirrors, we see that she was by the 3rd mirror from the end when the killer stabs her. However Dewey had already shot that glass out and only 2 were remaining out of the 6. (01:24:50)
Continuity mistake: In the scene where Gail and Dewey find the killer's voice changer, Gale's hands are clean, but when it shows her hands picking up the device, there's dried blood on them. But when it shows her hands again, the blood's gone. (01:16:05)
Continuity mistake: Gale and the killer go flying through the basement door, you see the door opens out, but when they crash through it, it opens in. Its not a two way swinging door, because you see the hinge at the top of the door to open it out, not in.
Revealing mistake: Jennifer swipes her card the wrong way at the studio and the door opens anyway. (00:57:15)
Continuity mistake: The knife that was thrown at Dewey left the killers hand with blood all over the blade, but was perfectly clean when the butt of it hit his head to knock him out at the top of the stairs. (01:26:55)
Suggested correction: Watch in slo-motion the sequence when he gets hit and you'll see the blade is bloody even during that. He then pulls out of his sleeve (literally!) a clean knife, but it's not supposed to be the original one, since he never retrieved it.
Plot hole: It has already been mentioned that a certain shot reveals that Sidney isn't wearing the bullet-proof vest when she should be. Further to this, most of the shots in the climax sequence make it impossible for her to be wearing one, as you can see the contours of her chest throughout. A bullet-proof vest would flatten the appearance of this.
Continuity mistake: When the killer and Sidney are locked in the screen room together and the killer slits the movie producer's throat, if you watch closely when he's talking to Sidney and waving the knife around that in the first shot there's blood on the knife and then it goes to Sidney and back on the killer and when it cuts back there is no blood on the knife. It then again goes back to Sidney, then back to the killer and the blood has magically reappeared on the knife. (01:36:00)
Continuity mistake: At the start of the movie when Cotton's girlfriend is being stalked by the killer, he stabs his knife through her bedroom door making a few large holes, especially with the first stab mark. Later, when Cotton finally gets to the house and is lookng for his girlfriend, he goes up to her door and there are now far smaller holes in the door, all in a nice pattern. When he smashes through the door, from the other side we can see there's no damage at all, then when his girlfriend emerges the stab marks are back, but in a different configuration. (00:07:35)
Continuity mistake: Christine gets out of the shower. In the next scene of her putting her nightie on, she has make up on. (00:04:15)
Plot hole: How did Kincaid get a picture of Sid from the Delta Lambda Zeta mixer in part 2? No one took any pictures of her. Aside from that, anyone who's seen pictures Neve Campbell online will know that that's a publicity shot from Scream 2 rather than something intended to be a "real" photo. (01:28:00)
Audio problem: When Tyson is running down the stairs he yells something but his lips don't move. (01:19:55)
Revealing mistake: When Sarah (the one who's supposed to play 'Candy') is stabbed, her blood is dried when she slumps over the door. (00:27:10)
Continuity mistake: When Gale finds Roman in the coffin, there's no blood on Roman's elbow when the shot is closing in on the coffin. When Gale opens the coffin, the elbow is covered in blood. (01:17:40)
Continuity mistake: In the first killing scene, the study which both Cotton and his girlfriend end up in has a white ceiling with a skylight. But when Cotton is stabbed and looks up at his killer the ceiling is light orange with beams across it. (00:05:35 - 00:09:15)
Factual error: In the beginning of the movie, the killer calls Cotton on his cell phone. When the killer hangs up on him, you hear a dial tone. When someone cuts you off on a cell phone, you don't get a dial tone. (00:02:40)
