Corrected entry: Sidney is told to hit Alt+M in the library when her computer freezes to access her message, but when she does this the sound effect used is of 4 keys being hit, not 2. (01:02:55)
Corrected entry: When Sarah Michelle Gellar is being stalked on the phone at her sorority house, she runs outside and the phone begins to break up, she walks inside and still can't get clear reception, then her friend talks to her and she hangs up. When the friend leaves the phone rings again - Cici is right near the front door and the phone reception is perfect, even though before she was at least a metre into the house and couldn't hear properly.
Corrected entry: At the cinema at the start, a few people come out saying how scared they are. Stab has been running for less than two minutes and hardly anything has happened. If they scare this easily, what are they doing at a horror movie?
Corrected entry: Cici says to the killer she's the "sober sister" in case anyone needs a ride home from the party, but they can see the Omega Beta Zeta house (where Cici is murdered) from the doors of the house where the party is being held. Why would anyone need a ride?
Corrected entry: When the killer is on the phone to Randy, Randy runs up to a guy with a mobile, who is right near the van that the killer is hiding in. Shouldn't Randy be able to hear the killer in the van which is right next to him?
Corrected entry: Mickey gives himself away as the killer. At the hospital after Derek is cut on his arm, he tells Sidney, what made him go back into the house anyway? The only people there were Sidney, Derek, and the killer. Sidney even has a strange look on her face after he says that, like, how did you know he went back in the house, but says nothing.
Corrected entry: At the party, when Mickey, Randy and Sidney's friend (forgot her name - the one who's studying psychology) are talking about The Empire Strikes Back, the girl says that "these furry creatures were nice" and Mickey says: "Ewoks - no, they sucked" (or something). But Ewoks appear in The Return of the Jedi, not in The Empire Strikes Back. It may not be a goof, since Sidney's friend may not know Star Wars trilogy that well - however Mickey should.
Corrected entry: As Dawnie answers the phone and the killer says "it's Ted" he can be seen sneaking in to the house in the background - he doesn't have a phone to his mouth. It can't be the second killer as he repeats the line "don't forget to set the alarm" which could have only been heard from inside the house.
