Continuity: When Julia shuts Kyle into the room full of hanging bodies, she begins to kiss Kyle, then starts to suck out his blood. After she sucks all his blood out, between shots the amount and position of blood over her lips and chin, changes.

Factual error: When Dr. Channard is looking through the sliding panels at the really crazy patients in the padded rooms, there is a man with a tattooed head wielding a crucifix. The fact that he is in a padded room means that he is a danger to himself and would not be allowed a metal tool that he could hurt himself with. Also, the door on the inside isn't padded like the walls which it should have been.

Visible crew/equipment: When Tiffany almost falls off of the ledge, you can briefly see a wire on her back.

Continuity: When Dr. Channard is being turned into a Cenobite, his tie disappears in some shots.

Revealing: When Julia takes the cigarette from the doctor in the room with the mirror, you can see, if you look closely, that there is no blood on the cigarette. But, the hand she has the cigarette in left some blood on the hand of the doctor.

Continuity: When Browning lies down while cutting himself, the mattress under him is dry and his blood is only smeared over his chest. Yet when the shot cuts to Channard and back, the mattress has suddenly become utterly soaked in Browning's blood.

Continuity: When Tiffany goes back to retrieve the diamond shaped box from Julia's grasp, the position of Julia's fingers around the box change between shots, as Tiffany reaches down to grab it out of her hand.

Revealing: When Julia first emerges from the mattress and is scrabbling on the floor, you can see the body double is actually wearing a thong.

Revealing: In the scene where Kirstie is in Hell searching for her father, she is running up and down Hell's corridor's, becomes winded and stops. As she does so, she slaps herself against a concrete corridor wall; when she does this, you can see that the "concrete" wall looks more like a rubber covering, as it moves with her.
