Other mistake: When Suzanne is in the trap there is one point where we see 36 seconds remaining on the clock. If you listen carefully you can continue to hear the clock tick down once per second, even offscreen, and you can count about 45 ticks before Suzanne is killed. (00:44:45)
Continuity mistake: When police are running to the public trap, there is someone on a push bike that gets knocked into the glass. Camera changes and he hits the glass again. (00:07:25)
Continuity mistake: When the car drops on Evan's girlfriend it leaves half of her head intact. When Homicide and IA are examining the body, the head is in a much worse state. (00:21:00 - 00:28:05)
Continuity mistake: Spoiler: When Hoffman gets out of the body bag at the police station, he kills the coroner. He then hides by the wall next to the door as the second coroner walks in. Camera cuts and Hoffman is now standing in front of the second door, a good three feet away from where he was standing before. (01:08:00)

Continuity mistake: When Hoffman kills the police officer opening a door, the door is only slightly open. When Jill gets to the police officer, the door is open much wider. (01:08:45 - 01:13:40)
Visible crew/equipment: In the first shot at the public trap, you can see a camera crane reflected in the mirrors.
Other mistake: The 30 second timer counting down in the garage trap actually takes 87 seconds to count down. The first 17 seconds take 72 seconds to pass. (00:20:15)
Continuity mistake: In the public trap, the amount of blood on Dina's stomach is constantly changing. In one instant it goes from being almost covered to absolutely no blood. (00:07:00)
Continuity mistake: The amount of blood on Nina's face changes depending on the shot. (00:41:00)
Continuity mistake: When Joyce first sees Bobby, in one shot both hands are on the collar round her neck. In the next shot one is halfway down the chain. (00:32:15)
Continuity mistake: In the garage trap, Evan can be seen to grab hold of the steering wheel with the tips of his fingers on his right hand. Camera changes, and his hand has moved instantly. (00:19:35)
Continuity mistake: When Bobby pulls on the lever to open his cage, he has one hand on the handle in one shot and in the next shot, he has both hands. Camera changes, and he's back to one hand. (00:31:20)
Visible crew/equipment: When Jill walks out of the police station, watch in the glass and you will very briefly see a boom mic and stage light reflected. (00:16:35)

Continuity mistake: In the garage trap, Evan is reaching through the window with about 12 seconds to spare. The camera changes, and his reach is nowhere near as far as it was before the camera change. (00:20:25)
Continuity mistake: Just before Nina dies, Bobby covers her mouth with his right hand, and holds the side of her face with his left. When he does, his hands are apart. Camera changes and his hands are now touching. (00:41:00)
Continuity mistake: Bobby presses play on the publicist's tape. However in all other shots the play button is not pressed. (00:39:10)
Audio problem: When Gideon says to Jill "get comfy" his mouth doesn't move. You can see the side of his mouth and it doesn't move. (00:35:35)
Continuity mistake: When we see the bear trap at the start of the film, there is a small amount of blood on the trap from when Hoffman was in it. Later, when it's left on show for Gideon, there is a lot more blood on the trap. The device is nowhere near any other victims for their blood to spill on to it. (00:09:35 - 00:28:40)
