Jigsaw is lying on the ground with a gun in one hand, and a tape recorder in the other; the tape recorder is removed, leaving his hand empty. If both of his hands were occupied/exposed, he would have hade no way of depressing the button on the remote control to shock the prisoners. As seen at the end, when he shocks Adam the final time, the control is in his hand, not hidden anywhere else on his body. [Jigsaw isn't the one who shocks him. Zep is watching from the camera behind the mirror and shocks Adam from his location.]

Dr. Lawrence Gordon had thrown 1 of the 2 cigarettes to Adam. Adam even began to smoke one of them. Later on when Dr. Gordon slumps to the ground and says "How did I get here? I had everything in order" two cigarettes are on the floor in front of him. [While it looks like there is only 2 cigarettes on the box, I believe there are 4. If you pause is at exactly 1:00:09, and look at what is on the ground on front of Larry, you can see 3 cigarettes (one by his hand, one by the lighter, and one by something that looks like a piece of paper), and we know that one is still in the box because that is what he switches the poisoned one with. (Clarification, stop motion is not valid in identifying mistakes but I believe acceptable in refuting them)]

The entire film was written, financed, shot, edited, and released in a span of less than 12 months, a feat unheard of in the modern film industry. [This is not trivia, as there are numerous films released every year that are written, financed, shot, edited and released in less than 12 months. While it is commemerable, it most certainly isn't an "unheard" of feat.]

when Adam is going crazy in the beginning trying to get out of the chains look at his foot its touching the pipe then it is no then it is again. [People can move their feet fast if they are "going crazy".]

When Zep and Detective Tapp are fighting in the bedroom, Zep falls to the floor, well beyond the bed. The next shot, he is right at the foot of the bed, and much closer to Tapp. [Zep falls by the post and stays by the post. Tapp then comes in and tackles him as he is getting up by the post and they land at the foot of the bed.]

When Jigsaw gets up off of the ground, when he says to Adam "the key to that chain is in the bathtub", if you look at his inner right arm, there is a black wire on it. The wire is attached to his arm by masking tape. [How is it a mistake? Jigsaw might have been using the wire and had to keep it in place.]

You can see the hole in Adam's shirt (in the scenes after he beats Zep with the toilet lid) where the bullet went through his shoulder, but it's obvious that there's no hole in his shoulder. It's visible when he's grabbing at it. You can see the blood-stained skin, but it's completely smooth, no hole or anything. [This may, in reality, be the case. However, as far as suspension of disbelief is concerned, his shirt could easily have shifted positions so that the wound is no longer visible. There is no way to determine whether or not the wound *should* be visible in this shot, and so this can't be considered a mistake.]

When they show a close-up of the feet of the "burn victim" (who's surrounded by glass on the ground) he's barefoot but when we see him running around he's wearing shoes? [No, he's barefooted the whole scene. There is a closeup shot of him stepping onto the glass and you can see that he's barefooted, as he is through his entire scene. Part of it is speeded-up, so it's a bit difficult to see at times, but he's barefooted.]

Several times after Dr. Gordon saws his own foot off we see his full body. There is blood around him but never any actually coming from where his foot used to be. In other words, he's not bleeding. [An unusual, but not unheard of, side affect of severe shock.]

When Adam throws the photo to the doctor, we see it from Tapp's point of view; from the camera behind the mirror. We see it cut from Adam tossing it to Dr. Gordon catching it, however, there is only one camera recording them. A cut would be impossible. [There is only one camera recording them, but for the movie there are several cameras showing the action from multiple angles. When the scene cuts, it is not meant or required to be the camera recording them.]

Included in the package of photographs Andy finds in the toilet, is the photo of Zep peering out the window of Dr Gordon's house. In a previous scene, however, we see that the picture was taken by Danny Glover. How did it get into the room with Andy and the Doctor? [First of all, I don't remember him being called "Andy" once in the entire movie. It's "Adam." And secondly, the camera Danny Glover used was a video camera- not a still one. It's also from a different angle. Someone else took that picture, from below.]

The shard of glass that first tells Adam that there is a two way mirror in the room keeps changing position on the floor throughout the movie. [As they are in the room for about eight hours and the movie is under two hours, it makes sense that Adam would nervously handle objects around him during the un-filmed time.]

The Dr and Adam must be at least 6 meters (6.5 yards) away from each other (both completely stretching out not touching the body in the middle). However, they easily throw pictures back and forth with unflinching accuracy. [There are only two instances in the movie where a single photo is being thrown. The first time photos were exchanged Lawrence threw his entire wallet to Adam (who returned it), the second time Adam threw the single polaroid to Lawrence, the third time Adam flung a stack of large, stiff photos at Lawrence (and only a few made it all the way across), and finally when Adam throws the picture of Zep to Adam. To throw one single piece of cardboard or stiff, flat plastic that distance is not so difficult as you may think. It requires a certain technique, but it is easy to learn and can be done. And both times he does it, Adam has far from "unerring accuracy". Lawrence has to lie down and reach with his full length to get the photo. ]

When Dr. Gordon is tucking his daughter into bed, he is wearing a white t-shirt underneath his blue collared shirt, however when he is chained to the pipe in the bathroom with Adam, he is not wearing an undershirt. In both shots the top buttons of his shirt are unbuttoned. [Dr. Gordon is wearing an undershirt. This is seen when he takes off his blue shirt to use as a tourniquet for cutting off his foot.]

We find out in the movie that Detective Tapp loses his job and goes insane trying to find the killer after his partner dies during the Warehouse shoot out that occurred with Jigsaw. Lawrence explains that Detective Tapp started stalking him thinking that Lawrence was Jigsaw and due to this, Adam was even hired to take photos of Lawrence. At the very end of the movie, when we discover the true identity of the Jigsaw killer, a montage of clips are shown, including one from the warehouse scene showing Jigsaw's face visible behind his robe. Since Detective Tapp would have easily seen his face when attempting to arrest Jigsaw, he would have known for sure that Lawrence wasn't in fact the Jigsaw killer. [The montage is taking place from a different perspective. We saw the whole warehouse scene, and could tell that Jigsaw's face wasn't visible during any of it. They only showed it during the montage because you now knew who was behind it, and they were just showing it from a new, enlightened perspective.]

When Dr. Gordon couldn't dial 911 on the cell phone; the fact is that 911 is considered a high priority number, even though the outgoing calls are blocked. It is impossible and against the law for service providers to block 911 calls. [I work customer service for a major cell phone provider and it is true that it is against the law to disable 911 from phones but Jigsaw was a demented killer who went into painful detail in planning these events for every event possible. It would not be imposible to access third party software and block the calls directly from the phone after hacking the hex values in the operating system on the phone. I have used such products myself to enable/disable locked functions on my own phone.]

During the film, the two cigarettes are placed back inside the box, one bloody, one not. One is then given to Adam. Later on when Larry is crying, we see both cigarettes (clean) lying next to him. [Actually, earlier in the movie you see some flattened cigarettes on the ground while the doctor us shuffling around, long before the box is located.]

The room where Lawrence and Adam are being held in is at least 10 feet underground (we know this because Zep climbs down a ladder whilst running away from Tapp). Lawrence shouldn't be able to get a mobile phone signal, yet he manages to receive two calls. [Whether you get a cell phone singal is dependent upon a lot of factors. The depth is not the only one. It would be possible to have a signal.]

***SPOILER*** How did the man in the centre of the room (who we know is the mastermind of it all and not dead) get there without an accomplice locking the door? We know a possible accomplice wasn't Zep. [The door was not locked. Dr. Lawrence couldn't reach it with the chains on. Zep opened it right up at the end. So, it wasn't necessary to lock it. Also, both the Dr. and Adam were unconscious so obviously he set it all up, part of the game.]

If Zep had a "slow-acting poison" in his bloodstream, why did he play the game? Any rational human being (especially one who worked in a hospital) would simply have gone to an emergency room, had his blood analyzed, and been given an antidote. Game over. [Zep wasn't a rational human being to begin with. Also, anyone who found out there was a poison in their system, would want to get the antidote from the person who put it in there. There's no simple check for poison - without knowing exactly what it is, finding that out can take a huge length of time and finding an antidote could take even longer.]
