Continuity mistake: In the opening scene Christine is completely dry when she steps out of the shower. (00:03:05)
Suggested correction: To be fair, "completely" is a bit of an overstatement. Her hair is dry, she has makeup, she's not quite convincing and other entries remark that. Her upper body is wet, though.
Continuity mistake: The ice pick remains free of blood even when Sid has stabbed the killer with it twice.
Continuity mistake: When Sarah tries to fix Roman's statue's head, her hair is over her face, when she goes to answer the phone her hair is pulled back behind her ear. (00:23:20)
Continuity mistake: Gale's bangs change lengths throughout the film.
Continuity mistake: In the scene where Jennifer gets killed and falls through the mirror look at Dewey's hair it's all messed up, but in the scene right after that when Dewey and Gale are looking for Tyson his hair's all combed back again.
Continuity mistake: Before Sidney pulls the killer out of the door on the house set, we see the bedside table is lengthwise against the wall. As the killer falls towards the bed it's turns 90 degrees, so the bed is a bit closer to the door. (01:05:45)
Continuity mistake: At the part where Sidney is on the set of her house and the killer is chasing her up the stairs, she runs right by the plants, but in the next take she is right next to the plants just about to throw one. (01:05:25)
Suggested correction: Sorry but no; she runs by -some - plants, and in the next take she is right next -other - plants, which she throws at the killer, who is just passing by the -first - plants. You can see both plants at the same time on screen if you are watching a version in the proper format.
Continuity mistake: Dewey rolls down a hill after shooting at the killer. The cut on his forehead changes shape from circular to two parallel lines then to a straight line and a waved one.
Continuity mistake: In the scene where Dewey and Gale are having lunch, Dewey asks her "Why would the police come to you?" In the background, a waitress in white walks by. Then they switch to Gale and the waitress has vanished. (00:28:30)
Continuity mistake: Roman's sideburns change lengths towards the end of the movie.
Continuity mistake: At the end of the movie when Sidney is lying on the floor, Roman is pointing the gun to her head about to kill her. The gun is clearly pointing to her head/neck area when he shoots, but Sidney still lives and shows him she was wearing the vest. The vest protects her chest and Roman shot her in the head.
Continuity mistake: Jennifer's house, the door just opened on its own. For some reason, Angelina and Tom don't shout back at Dewey and ask what's up, but rather jumpscare him. With Dewey's gun pointed at him, Tom has both hands in the air. In the same shot he lowers the right hand, but in the next he's with both hands up again. (00:43:20)
Continuity mistake: Look at the shirt David Arquette is wearing when he's out at lunch with Gale, heading then to Jennifer's house for the first time. They learn about Sarah's murder and head to the crime scene, and Arquette is wearing a different shirt he'll wear for the party later. Admitted by Wes Craven himself in the DVD commentary track. (00:33:40)
Continuity mistake: When at the diner's Gale answers "Well, I have written the definitive book about the Woodsboro murders", her arms are open; her hands were joined earlier. (00:28:30)
Continuity mistake: When fake-Gale mentions "your private self-loathing", an extra exits the frame to the left side. Over five seconds pass before the extra walks into another shot of the dialogue. And there she is again, but this time redoing her walk from the beginning, when Dewey embarrassed repeats "Little girl inside." (00:17:05)
Continuity mistake: Jennifer is reading the fax page using her flashlight; without moving her hand, she holds the sheet by the top corner at first, then in the bottom half. (00:44:25)
Continuity mistake: Stone falls face down in front of the entrance, his arms raised forming (very roughly) right angles. When Dewey screams to the others to get inside, Stone's left-hand touches his head. (00:43:45)
Continuity mistake: Steven Stone picks a few coins from Dewey's counter. You can see that there are 5 left in the wide shot, but only 4 in close-up. (00:42:10)
Continuity mistake: Confronted by the cops, the director says "I did not call Sarah Darling." In the background, look at the dark-haired extra that joins the other two by some stage equipment. A couple of cuts later she's just walking by them. (00:35:10)
Continuity mistake: When the cops go talk with Roman to ask him about his meeting with Sarah Darling, you can notice that Jennifer's bodyguard grew longer sideburns in the space of minutes since the scene at the house. Noticed by producer Marianne Maddalena on the DVD commentary track, and apparently they had some talks on set about that. (00:35:00)
