Other mistake: In the library scene, the guards are harassing the inmate by throwing books on the floor to make him pick them up.One of the guards drops a book on the floor to tell the inmate that he missed one but when he comes back to pick it up he actually picks up 3 books. (00:48:50)
Other mistake: The photo of Silvia and her brother, walking on the road with guns in Africa, looks like a composite and is obviously a fake made up for the movie. The images of those two look flatter and have slightly different contrast compared to people in the rest of the photo; separate photos of them have been cut and pasted onto the road photo.
Other mistake: When Frank shows up at Audrey's house, the cops are patrolling the grounds for security reasons. One cop sees that a glass pane in the french door has been smashed, to allow an intruder to unlock the door from the inside. But when the cop opens the door, we see that there is no lock, or even a latch, on the door.
Other mistake: During the film Ethan Hawke's pills are talked about between him and his evaluator. When you finally see him open his pill container, it is clear that the pills are actually Ice Breakers breath mints. You can see the trademarked "Flavor Crystals" (the dark blue spots on the white mint). (01:20:25)
Other mistake: The drip-meter that is supposed to administer Jigsaw's medication is not turned on. Anyone who has spent time in a hospital and seen one for real knows that a lot of numbers are shown on the displays when it is running to show medication status. (00:13:50)
Suggested correction: It's not specifically stated that the machine is in use. That's just an assumption. It could be set dressing he's using to enhance the perception of his condition.
Other mistake: In the fight after Matt gets ambushed, as the gangs collide, Matt gets knocked down, yet in the next shot he gets knocked down again. How would he be able to get back up fast enough to get knocked down again straight away?
Other mistake: When Ben lies wounded in the open, we are treated to a solar eclipse followed by a full moon. These events must be 2 weeks apart. Long enough for Ben to have grown a beard (which doesn't happen), but too long for him to survive without water.
Other mistake: When Domino is narrating introducing Alf as the driver, when everyone loads up to leave Domino gets in the back and Ed in the front, about 5 seconds later they have switched places. (00:31:15)
Other mistake: When they open the bag of money and fan through it, you can see the back bill says TWELVE - as in a twelve dollar bill.
Other mistake: In the scene where Jessica Alba has just cut off the guy's hand she was cuffed to and she is running around the boat, the handcuffs don't have a spot of blood on them.
Other mistake: During the infiltration in the carrier, Ice Cube steals an M2 Bradley and drives it around damaged for an extended period of time; the flames keep burning with different intensity always at the same spots; one wonders what makes the same point of the armor and the very bottom corner of the back ramp for so long, without spreading at all. (00:56:00)
Other mistake: In the beginning when Yuri sells his first gun, an Uzi, in the hotel room, he states "It shoots hollow points." Yet all the ammo in the case are full metal copper jackets.
Suggested correction: It's the first time he tries to sell a gun. He is just wrong about the bullet type. Common mistake to make for a rookie.
Other mistake: When the detective plays the recorded phone call with the criminals, there are 2 scenes about that. In both scenes, in the background, there are injured people walking with the policeman (duplicated scene).
Other mistake: Captain Stanley takes the lid off a small bottle on his right and puts the lid on the desk. He pours a drink and the lid miraculously appears in his left hand. He then screws it on the bottle. Screw top bottles weren't around till 1920. (00:54:50)
Other mistake: The rear interior view at St. Mark's shows "pews for two" along the left-hand side and there is not enough space on the right-hand side for similar pews. In the front view, there are "pews for two" along the left-hand side and no room for pews along the right-hand side. (00:10:52)
