ok, as others have mentioned, The opening scene, the autopsy, actually takes place after the events of the movie. The first scene chronologically is the trap with Trevor and Art, the two guys chained to the machine in the center of the room (Trevor was the blind guy, art was the guy with his mouth sewn).
the big main twist, is that Saw IV is actually taking place at the same time as Saw III. Rigg is going though his tests and Agent Strahm is going through his investigation in Saw IV at the same time that Jeff and Lynn were going through their tests in Saw III. Everyone was expecting Saw IV to be s sequel, when in reality it was a “midquel”.
Thank you for your reply, Aaron…but who was the detective? Was he in any of the other SAWs? I don’t remember ever seeing him
the other detective, the one who was stapped into the chair next to detective matthews on the ice block, was detective hoffman. Hoffman made his first appearence in Saw III and was seen pocketing evidence from a crime scene. This obvious forshadowing lead many fans to figureout pretty quickly that hoffman was the new apprentice.
don’t remember ever seeing him…I remember the guy who was standing on the ice block, but who was the detective standing over Jigsaw when he was dead in the infirmery?
this was Agent Strahm, his character was first introduced in this movie.
