Continuity mistake: Cotton arrives at his apartment; seen from behind, he leans into the door putting his right hand on the frame. Side view and he's leading with the left. Very similar mistake a handful of seconds later; look when he moves up the stairs. He gets one foot on the last step and it's the right foot, then it happens again, but it's the left foot that leads. (00:06:20)
Continuity mistake: Christine turns off the stereo. Look at her hair, and keep looking as she walks along the corridor. The hair keeps changing position over her shoulders between takes. (00:04:50)
Revealing mistake: Cotton is trying to reach his girlfriend using his phone. He shouts "Pick up the phone!" then curses because he has to quickly sverve. In the last shot of his maneuver at that crossing, two other cars have to zigzag to avoid a collision. Skidmarks which match their motions are already present on the asphalt, very likely from a previous take. (00:03:25)
Continuity mistake: Cotton is talking in traffic using his car phone. Notice the way he holds it in the very first shot; his pinky finger is behind the receiver, but it's on a different position after the cut. (00:00:35)
Other mistake: Cotton's opening line in the movie is that he won't go below 1 million bucks as he's risking his reputation for the cameo, furious that they can't write him a decent part for the Stab movie. So he's still negotiating, but the news story later in the movie says he filmed the cameo the day before.
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: 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.
Other mistake: June 28 was a Monday in 1999. Jenny McCarthy was killed the day before, so on a Sunday. The scene takes places the evening (there's sunlight when it begins) after the night scene with Sidney; it is however uncertain if it is actually supposed to be the same day, or the day before, a Saturday. Therefore, Cotton, murdered a day earlier, was killed on either a Friday or a Saturday, but when he was killed there was a promo on TV about "tomorrow's" episode of his talk show, which is on during weekdays and so wouldn't be on for the weekend.
Revealing mistake: The two faxes Jennifer reads are a single document that arrives with a timestamp of 21:05 at page 1, and of 21:07 for page 2. They arrive less than thirty seconds apart, and same for page 3, printed at 21:09. (00:44:20 - 00:44:50)
Other mistake: You can read the date of the event at Jennifer's house on the fax; it's June 28 1999. However, if you look at the director's office in the scene with Sarah, June was a very light month with according to the post-its mostly scouting for locations and such, and no shoots were scheduled in that month, as opposed to August that is full of those. All the previous scenes at the studio involved the actors on set for their scenes, and the news voiceover says that Cotton shot his cameo role the day he was killed.
Character mistake: Stone catches Gale snooping around and Dewey takes her aside to the kitchen to have a chat. She updates him about the latest news in the investigation, "Sarah's call didn't come from his cell phone." However Courteney Cox mangles the name and calls her "Sterra." Noticed by Wes Craven in the DVD commentary track; he even identifies the scene with "Oh, this is the scene when she calls Sarah 'Sterra' "and the editor references the similar "Roman=Ronan" mistake that happened earlier. (00:40:20)
Other mistake: Gale arrives at Jennifer's house for the party, rings the doorbell, but inexplicably, nobody answers. Noticed by Wes Craven in the DVD commentary; they said they "got away with it" by not adding the sound effect of the doorbell ringing in post so most people would Miss the gesture. (00:39:00)
Revealing mistake: When the house blows up and Dewey, Gale and Jennifer jump off the balcony, we find that Gale is near the car, the killer jumps up behind her. Dewy takes a shot at him with a gun and it is obvious that the killer awkwardly slams himself against the car window, rather than being caused by the impact of the bullet.
Suggested correction: Actually he would have to fake it because it is obvious, and later found out that he has a bulletproof vest on. if he wouldn't have faked it, everybody would've known that he had one on.
He faked really badly that being shot sent him smashing against a car, to avoid being suspected of wearing a bulletproof vest? How does that work? Dewey in the dialogue thinks he didn't even hit him.
Yeah, I'm with Sammo here. I don't really get the logic of the correction. I think it is just really awkward blocking/choreography/camera placement, and I do think the original mistake probably stands as-is.
Visible crew/equipment: When the two detectives drive into Sunrise Studios, Kincaid says he's going to talk to studio brass about the photos. Wallace gets out of the car, and Kincaid tells him to keep an eye on Sidney. As Kincaid drives off, we can see the reflection of the microphone and also a bit of the camera beside Kincaid. (00:52:45)
