Corrected entry: 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 and Dewy takes a shot at him with a gun and it is obvious that the killer purposely slams himself against the car window to make the gun look powerful.
Corrected entry: When Martha Meeks sees Sidney outside the door in Sunrise Studios, Detective Kincaids partner and a black officer runs up to her, thinking that she is a criminal, and next time you see them two the black officer is not there, but a different person.
Corrected entry: When the killer calls Syd at the police station and tells her that he has Gail and Dewey, she asks, "How do I know those are their real voices?" (Well, the killer finishes the sentence.) But Gail had just found out that the killer had a voice changer with all their voices. So if Gail had not spoken to Sydney before the killer called at the police station, how does Sydney know to ask about whether those are Gail and Deweys real voices?
Corrected entry: In the scene where Dewey and the killer are fighting near the basement door, which is not a swinging door, they both fly through the door (hitting it forward), but when it shows them falling down the stairway, the door is flying backwards.
Corrected entry: When the vest is hanging up the letters (LAPD) are across the upper part. When Sidney shows the vest to her half brother, the letters are at the bottom of the vest.
Corrected entry: In the very beginning of the movie at nighttime, as the helicopter is flying over the "HOLLYWOOD" sign, it shines a searchlight on it, lighting up the letters. The letters are cloaked in darkness. The "HOLLYWOOD" sign is lighted with surface-mounted spotlights at night. The letters should never have been dark. (00:00:05)
Corrected entry: After the actor is blown up by the fire in Jennifer's house, and after Dewey shoots the killer a couple times, Dewey finds another picture of Mrs. Prescott. The lines written in bold black on the back clearly show that there are many words. When Dewey looks at it, there is only "I Killed Her." To see it, make sure to look just when Dewey picks it up.
Corrected entry: Near the end, Sidney stabs Roman with a knife she picked up off the bar. Then she jumps over the bar and lands on the ground. She picks up Roman's knife, but when she stabs Roman in the chest, it's the bar knife again. (01:44:50)
Corrected entry: In the beginning of the final scene where Sydney tries to escape from the disguised murderer she runs into the library. In this room Sydney is looking for the hidden entrance behind the bookshelves. As she recognises a bright light underneath one of these shelves she knows which door to open. As she finally enters that room the bright light suddenly disappeared. The room is as dark as a coal chamber.
Corrected entry: At Roman's birthday party, Roman and Jennifer go off ALONE to find a missing room and end up in the basement. Later, Gale is looking for Roman and goes straight to the basement. She calls his name and gets no answer, but is adamant that he is in the basement and continues down to find him. Why would she think he was down there if she had no idea where he went?
Corrected entry: In the bathroom scene with Sidney, if they were so worried about her safety they should have sent bodyguards in with her.
Corrected entry: When Gale and Dewey are pulling books off the shelf a book falls right in Gale's face. You can see the very surprised look on her face - it wasn't meant to happen.
Corrected entry: When Cotton's girlfriend is in the shower, and she gets out her hair is completely dry and the rest of her is soaked.
Corrected entry: Why is the killer so surprised when Syd reveals she was wearing a bullet-proof vest when he'd been wearing one also?
Corrected entry: When Jennifer gets killed, it looks like as Roman stabs her, the two kinda press against the glass covering the closet. As Dewey shoots the glass, Jennifer falls through the glass, yet the killer is nowhere to be seen. It looks like to the right, there is a wall there, preventing him from running in that direction, yet if he ran the other way, he would have ran right in full view of Dewey and Gale. Instead, he's just magically disappeared.
Corrected entry: Towards the end of the movie when the killer confronts Sidney, she shoots him 6 times leaving a crescent of bullet holes in his costume, but the next time we see him the holes are gone. Later, when he reveals himself he shows Sidney his Kevlar vest and the bullet holes are back.
