Revealing: When Jake "kills" Chelsea, and his phone starts to ring, the phone is blinking, and vibrating. It falls to the floor, and Jake reaches for it, when he does this you can see that the phone is not actually ringing, because the screen is dark and the screensaver is active.

Continuity: At the beginning of the movie, the car the characters take to the party has European plates. Later on, the plates are American.

Continuity: When Adam's father starts playing with the box at the end, he has a just-lit, long cigarette in one hand. The shot cuts for only a second and the cigarette has burned down almost to his knuckles.

Continuity: After Henriksen is killed, Chelsea and Jake are shown driving down the road. At first there is no license plate visible on the rear door of her SUV. A few shots later the license plate appears.

Plot hole: The Hellworld website at the beginning of the film has eerie music and also Pinhead's voice reciting some of his famous lines from other Hellraiser movies, which is impossible; there's no way that someone could have gotten recordings of those moments in the past where he said the lines, so they couldn't be playing on an internet webpage.

Continuity: When Chelsea returns back to the house, she runs through the front doorway and the door behind her is still open. In the next shot, the door is closed.
