• Continuity: When Adam finds the Polaroid of Dr. Gordon's family gagged, his hands are holding the wallet differently between shots.
  
  
• Factual errors: After the doctor speaks on the cell phone for the first time and the line goes dead, there is a dial tone. Cell phones do not use dial tones.
  
  
• Continuity: When Dr. Gordon is leaving the hotel, he is seen pinching his nose when the photo is taken; when we see the photo he has covered his eyes completely.
  
  

• Continuity: When the two detectives break into John's lair, they examine the puppet under a red cloth. The puppet's head subsequently changes position between shots.

• Continuity: In the car chase scene, Zep is seen driving a late 1980's Ford Bronco II (could be a Ranger pickup because we only see the front). When he arrives at the warehouse, the truck has changed to an early 1990s Ford F-150.
  
  
• Continuity: When Zep is listening to Diana's heart, he pulls out a gun in an attempt to raise her heartbeat. While he's doing so, the shot from behind him shows the gun against Alison's head, even pushing a few strands of hair. The next shot shows the gun at least 6 inches from her head.
  
  
• Boom mic visible: After the first call Dr. Gordon gets on the cell phone, a boom mic shadow is visible on the bathroom door.
  
  
• Continuity: 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.
  
  
• Continuity: When Dr. Gordon is using the box to try to reach the phone he gets angry and tosses it to his left side. When we see his right side, the box is still lying there. A few moments later, when he is tugging on his chains in frustration, we see the box next to the door, in the direction that he threw it.
  
  
• Revealing mistakes: Close-ups of the newspaper clippings lining Tapp's apartment walls show headlines about the Jigsaw Killer's murders...but the articles have nothing to do with the headlines, and the datelines have the news stories in different cities, ranging from Virginia to California.
  
  
• Continuity: Dr. Gordon has two cigarettes in the box, one of which he throws towards Adam as part of the doctor's plan to make Jigsaw think that Adam is smoking a poisoned cigarette. Adam lights the cigarette and pretends to die. It cuts back to the doctor where we see the two cigarettes lying in front of him again.
  
  
• Continuity: When Adam is given the cigarette, he fakes his death and falls to the ground. The saw he broke in the beginning is lying intact on the right side of his head.
  
  
• Continuity: When Adam pounds on Zep with the toilet seat, he grabs his shoulder in pain. In the first shot of him holding his shoulder, his hand is soaked in blood. In the second shot, however, his hand is much cleaner.
  
  
• Continuity: When Adam is attempting to reach the tape recorder with his shirt his distance from the body changes between shots.
  
  
• Continuity: After Adam searches in the toilet bowl, his hand is covered in brown slimy water. However, after he removes the lid from the cistern, his hand is completely clean, and he clearly used his other hand to remove the hacksaws from the water.
  
  
• Continuity: While Tapp And Zep are battling for Zep's gun. Tapp has pushed Zep to the wall and Zep is turning his gun upwards to shoot tap from over his shoulder, the gun changes from a Springfield Armory .45cal to a 9mm Beretta M92 whilst Zep shoots and after Tapp dies, it changes back into the .45cal.
  
  
• Continuity: In the scene with the victim trying to open the safe in the room with glass shards covering the floor, there is a close-up shot of his bare foot stepping on the broken glass. In the next, speeded-up scene that shows him walking all over the room trying to figure out the safe's combination, he is clearly wearing shoes.
  
  
• Audio/visual unsynchronized: When the detective turns the corner and shoots the hooded killer (John) he is carrying a Shotgun, but when he ejects the bullet casing the sound it makes is from a metal casing. The only long gun that would make that noise would be a rifle. The noise the shotgun shell should make is a hollow plastic noise. The ejecting of the shell and the actual motion of the reloading must have been separate.
  
  
• Crew or equipment visible: After Amanda survives her reverse bear trap test, the Jigsaw puppet is seen wheeling towards her. If you look closely you can see the cabling controlling the puppet. This is in fact fishing wire which was used to control the puppet. (Possibly deliberate.)
  
  
• Continuity: The stains on Adam's white t-shirt from the toilet disappear and reappear throughout the film.
  
  
• Continuity: Early in the film, Adam breaks his saw while trying to cut his chain. Later in the film, while Adam is getting shocked, we can see his saw lying next to him, completely intact.
  
  
• Continuity: When Dr. Gordon empties the contents of the envelope into his hand, the Dictaphone cassette is not visible clearly from the first camera angle, but is visible in the next.
  
  
• Revealing mistakes: When Dr. Gordon is about to leave after tucking his daughter in and his wife is confronting him, the lack of a ceiling and unfinished wooden rafters are visible in the set of their otherwise elegant home.
  
  
• Incorrectly regarded as goofs: When Tapp and his partner go after the Jigsaw Killer on their own, they do not take a SWAT team or uniformed officers because they have no warrant, and it is thus an illegal search which the police would not provide support for.
  
  
• Errors made by characters (possibly deliberate errors by the filmmakers): When Detective Sing asks Dr. Gordon to stay and listen to Amanda, he says "I wanna know if you wouldn't mind sticking around and listening to her testimony." What she was doing was giving a statement, not testimony, and any detective simply wouldn't make that mistake.
  
  
• Continuity: At the early scenes of the film, the laid down dead body's left toe stands or down on the floor between shots.
  
  
• Continuity: When Detective Sing first enters the warehouse through the door, he's holding the shotgun left handed. However in the next scene, he changes to hold it right handed.
  
  
• Incorrectly regarded as goofs: When Adam pretends to be dead and receives an electric shock, if there had been an electrical wire running along the chain to his leg shackle he would no doubt have cut this wire when trying to saw the chain earlier. However, there's no need to run an unseen wire along the chain to the shackle: the chain and the pipe it is attached to are made of metal and could conduct the current without the use of a wire.
  
  
• Incorrectly regarded as goofs: When Adam asks Dr. Gordon if he's going to have any more kids, there is a small, white spot on the right side of the screen visible for less than a second. This is likely a single-frame anti-piracy watermark or a defect on the film. They appear several times in the movie, especially in the final reels.
  
  
• Revealing mistakes: After Gordon and Adam find the box with the cell phone and cigarette, Gordon tries to call 911. However, when he tries you hear 3 different tones when he pushes the buttons for 911. If he was pushing 9-1-1, then you should only hear 2 distinct tones with the last one repeated.
  
  
• Continuity: After filming was over, Leigh Whannel played more parts to fill in some gaps in the movie. When Sing is entering the wear house, it is really Leigh and if you watch the full screen version, you can see Leigh, not Sing entering. Also, when Amanda is getting the key from the dead person, it is actually Leigh's hands not Amanda's.
  
  
• Continuity: The hand Adam uses to smoke his cigarette, is the same hand that he used to search in the toilet. Not too sanitary, but then again, neither is smoking.
  
  
• Factual errors: Both Adam and Lawrence receive electric shocks through their chains. However, for the shocks to occur, the current must have a path to ground through the body, and both men are lying on a floor made of ceramic tile, which is an insulator. Even if the floor were somehow able to conduct the shocks, the pipes to which the chains are attached also contact the same floor; any current applied to the pipes would ground directly to the floor, not through the chains and victims.
  
  

• Continuity: SPOILER: When Dr Gordon begins to saw his foot off, the blood seen covering his neck and top disappear in subsequent shots.
  
  
• Continuity: SPOILER: When Dr. Gordon shoots Adam there is blood spattered on the wall but when Adam falls to the ground it has disappeared
  
  
• Continuity: SPOILER: When Tapp is fighting with Zep, Tapp is holding on tightly to Zep. The gun Zep has in his hand is a completely black gun, but when he slips out of Tapp's arms and accidentally shoots him, they both fall on the floor. The gun Zep has turns into the silver and black gun that he used throughout the movie.
  
  
• Continuity: SPOILER: After Lawrence leaves the bathroom Adam leaves a bloody hand print on his Lawrence's right shoulder, but when Adam plays the tape recorder there is a flashback of Lawrence saying to Zep, "Why?" then Zep say, "It's the rules!" the hand print Adam made on Lawrence can be seen on his shoulder when it wasn't there when it actually happened.
  
  
• Revealing mistakes: SPOILER: After Lawrence saws off his foot and Zep is down, he starts to crawl out of the room. When he is leaving and a shot shows up his pant leg, you can see his foot hidden inside the pant leg for one split second.
  
  
• Continuity: SPOILER: When the camera is switching back and between Zep and Alison when Alison gets free and has the gun. The gun switches between Alison's right and left hand. When the camera is looking at Alison, she has her right hand outstretched, waiting for the phone and the gun is in her left hand. But when the camera is looking at Zep (over Alison's left shoulder), the gun is in her right hand with her left hand outstretched waiting for the phone.
