Continuity mistake: When Dewey says "I'm 25 years old" to Gale, three people are coming down the stairs behind him. Next shot and they already went way past Gale. Same in the closing part of the scene as she says "Please, call me Gale!" and the guy above Dewey who is going up the stairs passes her by. (00:48:55 - 00:50:15)

Continuity mistake: Mr. Himbry calls the two expelled students "Desensitized little sh*ts", pointing the open scissors at him. In the next shot he's looking at him but he changed position, since the scissors are gone from frame. (00:45:20)

Continuity mistake: Sidney bumps into Billy around the corner after she walked away from Tatum and Stu at the lockers. Behind Billy there's a short-haired student with a sleeveless striped top that turns the corner followed by a long-haired brunette. The two extras appear again in the next shot behind Sidney, taking almost 10 seconds to walk 2 meters. (00:43:00)

Continuity mistake: When Sidney tells Tatum to wait "Just a second" because she's going to talk to Gale outside school, Rose McGowan's bag has slipped off her shoulder during the take, but in the next shot she's wearing it properly. (00:39:55)

Sammo ★

Continuity mistake: Sidney is in Tatum's bedroom. Tatum is playing with her rabbit toy while Sidney turns the other way. Look at the notebook, pen, ice pack. Sidney doesn't do anything but a few seconds later Tatum's mom calls her and when Sidney turns towards her the objects have changed position. (00:37:10)

Sammo ★

Continuity mistake: When Tatum comforts Sidney telling her "I'm gonna get you out of here, okay?" in the background her brother comes out of the door holding the 'Father Death' costume box. The sheriff by him is holding an orange paper, but at the cut he's got his hand behind his back, no orange slip. (00:35:00)

Continuity mistake: When the killer pops out from the closet after Sidney closed the front door, he's holding the knife above his head, but it cuts then to a shot of him raising the hand from a position below the waist. (00:28:35)

Sammo ★

Continuity mistake: The gang is chatting about the murders and their interrogations. Stu responds "There's no way a girl could have killed them" to Tatum's complaint that nobody asked her if she likes to hunt. In these two shots, Rose McGowan's hair is wildly different. (00:20:00)

Sammo ★

Continuity mistake: When Tatum asks "Why would they ask you if you like to hunt?" look at the blue backpack. Next shot, and the light is on it in a different position than before. The position of the various actors as they eat grapes also changes. (00:19:50)

Sammo ★

Continuity mistake: Gale falls back on the unconscious Dewey after Billy kicks her. Her jacket is draped across the chest touching the white button of her vest. When Billy gets on his knees by her though, the jacket is fully open. (01:37:30)

Sammo ★

Continuity mistake: Once Billy is done slashing his accomplice, he points the knife at him and tells him what to do; the knife hand keeps changing position between shots. (01:36:00)

Sammo ★

Continuity mistake: When Billy tells Sidney that her mother is the reason his parents split, he's pointing the knife at her, but not anymore in the reverse shot. (01:33:00)

Sammo ★

Continuity mistake: Look at Matthew Lillard once Billy says "What's the matter, Sidney? Looks like you've seen a ghost." He's scratching his cheek, but in the next shot his arm is down his side. (01:31:15)

Sammo ★

Continuity mistake: Billy's expression is entirely different in the two shots when he raises his gun and points it at Randy. (01:30:25)

Sammo ★

Continuity mistake: In the scene at the TV truck, the killer's knife is blood-free even after slicing the cameraman's throat and stabbing Sidney, if you look at him when he tries to open the door and when he gets in. When he shakes his fist at Sidney for running away though, the knife is all bloodied up. (01:24:00)

Sammo ★

Continuity mistake: When the killer slits Kenny's throat, Sidney in the background stifles a shout with one hand on her mouth, both hands in the next shot. She opens her hands but her right hand is still glued to her face in a further cut. (01:23:40)

Sammo ★

Continuity mistake: When Kenny the cameraman spots the front door open and turns around to look again at the truck, Sidney before the camera cuts away is turning all the way to look at the monitor as well, but in the next shot she's still facing Kenny. (01:23:35)

Sammo ★

Continuity mistake: Plummeting from the roof onto a boat, Sid causes a wetsuit (or a similar kind of fabric) to fall off. In the closer shot, the cloth is much more entangled than in the other view - look at the pink band. (01:21:55)

Sammo ★

Continuity mistake: Off-balance on the roof as she shouts for help, Sid is hanging by the window with one hand or both depending on the shot. (01:21:45)

Sammo ★

Continuity mistake: Randy pauses the movie and gets up to explain "the rules." Stu comments "Have an aneurysm, why don't ya?" Matthew Lillard's hand is in a different position in that shot. Not only that; the only extra you can partially see on the right in the background, in the previous shot made a disappointed gesture and lowered his arm, and in this new shot he lowers it again anew. (01:13:05)
