The franchise in general:
- Fan Nickname: Pinhead was originally listed in the first film's credits as "Lead Cenobite," and Barker himself has been known to say calling him "Pinhead" makes him sound stupid. Which didn't stop the sequels from adopting the fan nickname as the official one.
- Franchise Zombie: The first four films have an actual continuity and contribute things to the series' Myth Arc like the Labyrinth, the origin of Pinhead, the LeMarchand bloodline, and the death of Pinhead. Afterwards, creator Clive Barker cut ties with the franchise and every subsequent film is a Dolled-Up Installment that drastically changes the role of the Cenobites from neutral extradimensional pain seekers to demonic punishers of the wicked with Reality Warping abilities and contributes nothing to the Hellraiser universe aside from throwaway Continuity Nods.
- The Other Darrin: Starting with Revelations, Pinhead is played by Stephen Smith Collins instead of Doug Bradley.
The original film:
- Playing Against Type: Played With. Andrew Robinson, who's best known for playing the Scorpio killer in Dirty Harry, plays an average loving family man named Larry Cotton. Larry is oblivious to the fact that his wife is cheating on him with a demonic apparition of his brother and killing people. It becomes subverted when Frank kills him and takes his skin for disguise, making Andrew play Frank by proxy.
- Throw It In: Andrew Robinson thought "Jesus wept" sounded so much cooler than the scripted line "Fuck you". Clive Barker agreed, and the line made it into the movie.
- Troubled Production:
- The film was shot in a real house, which causes problems when you are trying to fit all the cameras, lights, boom mikes and other equipment in a regular-sized room and still leave enough space for the actual scene to be played out.
- Andrew Robinson and Clive Barker couldn't stand each other, and according to some reports they had to be pulled apart from being at each others' throats a few times.
- What Could Have Been
- The music for the film was originally done by Coil (they were hired by Clive Barker after he listened to one of their albums and nearly got sick due to how brutal their music was) but the studio ended up rejecting it due to its content. Their score ended up getting released separately and Christopher Young did the score that ended up in the film (which launched his career as a composer).
- A video game adaptation was planned for the Nintendo Entertainment System by none other than Color Dreams, creator of many low-quality unlicensed games for the system. It was to be the first of their games to use what they called a "Super Cartridge" that would've had four additional megabytes of RAM, sprite manipulation, and fully animated backgrounds, among other things. However, due to the production costs and the expected higher price than a standard NES game, the game was canceled.
