Continuity: When Pinhead is just about to start killing everyone in The Boiler Room night club, a man catches the first hooked chain that Pinhead unleashes. Yet when you look closely as you see the man holding the chain there is no hook, but a piece of wire.

Continuity: In the scene where Pinhead is in the church, he stands behind the table, and the candle to the right of him is straight. He then pushes the cross off the front, look at the candle, it is now on a slant then in a split second the candle is straight again as if it had never been touched.

Continuity: In the first hospital scene, where a kid dies by the hook-tipped chains in the operating room, there is a point where his head just explodes. Later, when Joey opens the door, for a second you can clearly see the kid's body, still with a head.

Deliberate "mistake": Joey finds Channard's photo of Capt. Elliot Spencer in the closed art gallery but Kirsty stole that photo and gave it to Pinhead in the second film, where it was left on the floor of Hell. Also, all the sketches of the box were amongst the things from Channard's institute but those pictures and the other similar ones were from Dr. Channard's home collection. They were never kept at the institute.

Continuity: At the end of the film Pinhead tricks Joey into giving him the puzzle box by posing as her dead father. As soon as she hands the box over he takes a knife (or sickle or whatever it is) from his belt with his left hand and poises to strike. Then it cuts to a shot from behind and he's now gripping the knife with his right hand.

Deliberate "mistake": When Pinhead is killing the patrons at the club and they are running away to try and escape, you can see some of them laughing instead of screaming like they should be.

Revealing: After Joey runs from the club into the street and a car swerves to avoid her, it hits a lamppost which causes sparks; but look closely and you can see that the sparks appear just a split second before the car actually hits the post. The sparks were rigged and set off a second too early.

Continuity: At one point, Pinhead pulls nails from his head. These nails not only miraculously grow back, but are much longer than the ones we saw hammered in at the beginning of the second Hellraiser.

Continuity: At the end after Pinhead has 'absorbed' Elliot and Elliot pushes through to tell her to work the box, her hands are clean. Then she reaches for the dropped box and her fingers are bloody, causing her fingers to slip on the front of the box and stop her working it.

Revealing: Joey walks through a large room filled with dead bodies laying all over the place. As she walks, she steps on several of the bodies and then you can tell that they are made of rubberized plastic, because the squishing sounds that you can hear could only come from pressure being applied to something made from that material.

Deliberate "mistake": As Joey is running down the street and having things blow up all around her, you can see other people walking on the sidewalk not reacting to the destruction around them, even when something blows up just a few feet from them.

Continuity: In the scene where Joey goes to meet Doc at the Boiler Room and drives her car past his, you can see Doc's car door is open. When Joey goes to Doc's car, that door is shut and she opens it to look inside.

Continuity: One of the chains reaches from the sewer and grabs Joey by the sweater during the chase scene. Every time the chains are used in the other films, they are incredibly accurate. One grabs Frank by the hand, as he grabs for Kirsty in the first film, and another effectively blocks Kirsty's way in the second, but now they can only grab Joey's sweater. [Pinhead deliberately makes the chains miss because he's just trying to intimidate Joey at this point. He can't kill her until she gives him the box.]

Continuity: Pinhead is able to return to earth in the form of a statue. This is supposed to be the same statue as the one that rose up out of the mattress at he very end of the second Hellraiser, but that statue was made of wood, and was covered with living images of Hell, while the statue in this film is about four feet taller, and now made of solid stone or marble.
