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: 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: In the scene where the cast are hanging out in Jennifer's house with Gale and Dewey, the door opens by itself and Dewey points his gun out the door. When he calls out the names of the actors, watch the wall behind him and Gale, you can see a shadow of a cast/crew member on the wall.
Corrected entry: The "Movie Gale" learns that she gets killed next, based on the idea that the killer is going in the order of how they get killed in the script. That means that Gale Weathers dies in Stab 3. But when the "Movie Gale" gets killed behind the 2-way mirrors, you can hear her say that she is the killer in Stab 3.
Corrected entry: I think a few of the characters seem to have forgotten the 2nd victim in the opening scene. References are made to "Two dead people" when there were three and "three and a bodyguard" when there were five dead at that point.
Corrected entry: Towards the end of the film (after we've established that the killer is wearing a bullet-proof vest) why does Sidney bother to stab him in the chest? It's not as though she's forgotten because she then tells Dewey to shoot him in the head! (01:45:24)
Corrected entry: When Dewey is shooting at the one-way mirror he fires seven shots form a revolver (they only hold six) then he fires again without reloading and is surprised to find it empty.
