Continuity mistake: In the ending to the previous film, Lynn gets shot in the stomach and falls backwards through the plastic doorway. In this version she falls forward into her husband's arms.
Suggested correction: Absolutely, positively incorrect. Not only does she get shot in the back and fall forward into her husband's arm in both movies, but they literally use the EXACT same shot of her falling forward into his arms in both films, so it's flat-out impossible for it to be any different. Need proof? Look up "Saw 3 - Game over, ENDING (Amanda, Jeff, Dr Lynn and John) " on YouTube and pause around 1:12. Then look up "Saw 4 - "Game over", ENDING (Eric, Blank, Rigg, Jeff, Strahm and Hoffman) " and pause around 3:36... it's the exact same shot in both films.
Corrected entry: When Jill went to get Cecil's jacket, she didn't lock the door behind her, yet, when Cecil forced himself in, he had to unlock the door to get into the same room his jacket was in.
Corrected entry: Rigg pulls the red scarf off the blonde woman and we don't see where it goes. Then there are two closeups of the woman where the scarf is nowhere in sight, and she has nothing on her left shoulder. Then in the next shot, suddenly the scarf is covering her and the machine behind her, and part of it is draped over her left shoulder. (00:23:45 - 00:24:15)
Corrected entry: When the guy with the mouth stitched shut has put his legs against the machine to avoid being pulled anymore, a few seconds later you see him with his mouth open, enough for him to easily say something. At the end of the scene you see him being able to open his mouth easily, something he could've then done much earlier. And even if say his tongue was cut out to explain him not being able to say anything with an open mouth, he wouldn't be able to scream at the end either. (00:07:40 - 00:10:45)
Corrected entry: When Rigg awakens and his test starts, he is shown a video clip of Detective Mathews and Hoffman in their trap, and both are wide awake and looking around. Yet, only a few minutes later, we see the room that they are in, and you see them passed out before waking up for the first time. (You can tell they are waking up for the first time in that room based on their reactions and flashbacks.) This makes no sense, as they were wide awake in that room just moments earlier on the video.
Correction: There's no telling how long they have been awake and in that room for before he saw them on the video. Just because we see them wake up, after we saw them awake on the tape, doesn't mean that's the order things happened in.
Correction: The camera scene is just copied when Eric and Matthew wake up. If you look closely at the camera scene Hoffman is passed out and slowly wakes up. The next scene when we see them wake up Hoffman does the same movements.
