Corrected entry: Unless a lot of people died offscreen, there's no way the Professor killed everyone who worked on Travis' film. Look at the amount of people working on Amy and Toby's films - there would have been more than 8 people who would have recognised the film when the Professor sold it.
Corrected entry: When Amy and Vanessa are lured into the tower, a mannequin is dropped from above to scare them into running up the stairs. The killer then emerges from a downstairs room to chase them, so who dropped the mannequin?
Corrected entry: In another scene involving Amy and Vanessa, the killer comes out. Instead of going out the door they run up miles of stairs to get to the top with no exit.
Corrected entry: When Amy's being chased by the killer, she falls into the water. Now, when she gets "under" the killer, she is wet. Considering the fact that it is cold water, and there is a murderer after her. She is not shivering at all. Not from cold nor fear.
Corrected entry: When the girl loses her kidney she calls for police, but the dispatcher doesn't believe her and hangs up. This wouldn't happen because no matter what they have to send the police to investigate.
Corrected entry: When Reese is in the car with Amy, she tells her a story about a campus serial killer who murdered eight students (The plot of Urban Legend). However in that film Brenda kills only six students, her other two victims are faculty members [Could be that the character didn't have the story straight.]
Corrected entry: In one scene Amy is attacked. She has video tapes in her bag showing a death. She chucks her bag with one of the tapes in it to distract the killer. She runs away, he eventually gets the other tape but not the one in the bag - wouldn't that show the evidence?
