Saw IV

In the interrogation room a camera and a crew member is reflected in the 2-way mirror.

Between 50:44 and 50:45 during 8 picture frames (72998-73006).

When Rigg arrives at the shop, the clock shows 1:16.

But, at a second look, it's 3:46 When Agent Strahm has his outrage, after he has called Agent Perez's mother, the first time he knocks down the papers the computer screen shows "normal use".

When they show the knocking over again zoomed in the computer screen shows the windows welcome screen, then back to "normal use".

During one of the interrogation scenes a boom mic is visible in the reflection of the 2-way mirror.

When the two FBI agents find the tape and the puppet in the school building, the tape recorder can be seen running before agent Perez actually pushes the "play"-button.

At the beginning of the movie, the organ scale in the background can be seen reading just under 1/2 pound.

The needle never moves, even when John's brain is taken out of it a minute later, it still reads 1/2 pound and never moves to zero pounds when emptied.

During the autopsy, when the brain is taken out of the skull, it is not attached to the brain stem and spinal cord.

it is loose in the skull.

in reality, lots of dissections are needed for it to be done.

When Officer Rigg enters the hotel room with the box on the bed, there is a photo of his wife on top of it.

On the back of the photo, the words "she needed you" are clearly displayed in red ink.

However, as he opens the box, you can see the that the back of the photo now reads "she needs you" instead from the letters "eds" at the edge of his hand.

During the beginning autopsy scene, the person performing the autopsy puts his mask on upside down (the eye splash guard is at his neck).

As soon as the camera jumps, the face guard is positioned correctly.

When Rigg is watching the interrogation video of Jigsaw's ex-wife he is looking at several books and magazines about Jigsaw.

The book he picks up is titled "JigsawIs He The Murderer The Police Say He HIS?" When Art goes to stop the guy from jumping off the block of ice the first time, you hear the sound of the gun cocking.

In the next view we see the gun and the hammer is not cocked.

Ivan's pierced eye changes from his left to his right and back to his left in the scene where the FBI Officers discover his body.

When the scene with Perez on her way to the hospital ends, it shows Art sitting at the desk with the timer on 19.

Later in that scene he walks back over to the desk and the timer is on 19.

39 when about a minute of the scene had gone by.

During the flashback in which Jill is attacked by the man who "forgot" his jacket as she is leaving the clinic, she has to unlock the door at knife-point even though she never re-locks it when retrieving the jacket.

The door's lock is a deadbolt type and no knob is present, so it wouldn't lock itself automatically.

Art's second trap was the Spine Pincer, which was intended to slice through the back of his neck if he failed his test, but when he takes off his jacket (revealing the device) he bends his head and clearly shows that he can get his spine out of reach of the blades.

The pincers have no extension, so Art really has no obligation and no reason to subject Eric and Hoffman to their torture.

In the beginning of the movie, during the autopsy, John's skull is seen having the minor rectangular piece removed.

This, however, is not possible, as Lynn from Saw III removed the piece as part of his brain surgery.

When Rigg approaches the door to the classroom, in which the husband and wife have experienced their trap, the painted red '?' on the door is still wet.

When Rigg finds Jigsaw's last note for him in the desk drawer of the "FEEL WHAT I FEEL" room, it is first seen to have only one sentence"Become the teacher and save a life.

" In a subsequent close-up, a second sentence appears"Go back to where it all began.

" On the Unrated Director's Cut DVD, Rigg pulls the last steel spike out of Morgan and Rex and drops it.

However, the accompanying sound is that of a wooden rod landing on the floor.

At the end of Saw III, when John died, he has no facial growth, and during his autopsy, stubble is clearly visible.

Despite it being commonly believed that a person's hair can grow after death, it cannot.

However a corpse's skin can recede allowing hair under the skin which grew during life to become visible.

After Jill grabs Cecile's coat, he threatens her with a knife to open the door.

However, after she gets the coat she doesn't re-lock the door to get inside.

- PLOTIn a flashback, John is shown abducting Cecil at a Chinese street festival celebrating the Year of the Pig.

The last two years of the Pig were in 1995-1996 and 2007-2008.

This does not fit well with Jill's statement that these events took place shortly after John's diagnosis with cancer in 2004.

When Agent Strahm and Agent Perez debut at the discovery of detective Kerry's body, Strahm declares his theory of a third person helping Jigsaw and Amanda Young.

He could not possibly know that Amanda Young was involved at that stage.

When Art Blank is fighting with Detective Matthews (at around 5 mins), his cap is alternately off and on between shots.

Saw 4 is another great installment for the Jigsaw killer series. Surprisingly still going good, even good without Jigsaw.

This is the last Saw film that Darren Lynn Bousman would direct. Where would they go after killing everyone off in the last one?

Saw IV starts as Detective Hoffman (Costas Mandylor), SWAT team leader Officer Rigg (Lyriq Bent) & their team find the dead mutilated body of Detective Kerry (Dina Meyer) in one of notorious killer Jigsaw's (Tobin Bell) traps. FBI agents Strahm (Scott Patterson) & Perez (Athena Karkanis) both feel Jigsaw has some sort of accomplice & are determined to find out who it is, meanwhile with Detective Eric Matthews (Donnie Wahlberg) still missing & the bodies continuing to pile up Officer Rigg just can't let it go & somehow feels responsible & helpless.

The fourth entry in this extremely visceral series continues to dish out the same kind of stomach turning moments and intense moments that fans came to expect. It works overtime to tie in with previous films and as a result may not stand up to a lot of scrutiny.

More like Saw 3.5, as this film takes places simultaneously with the previous installment.

This fourth sequence is bad.

Saw IV is all about torturing and killing people in the most sadistic way possible. That's all it is.

Back in 2007, "Saw" and it's sequels were a success, but this fourth part is the weakest of the franchise. Darren Lynn Bousman directed the part 2 and 3, two great sequels, but with this fourth part he went to a bad script.
