Trivia: When Joey's television set is flipping through the channels all by itself, on one of the channels is an interview with Tony Hickox, the director of the film.
Trivia: Paula Marshall, who plays Terri, once went to a Bruce Springsteen concert several years after the movie came out and just so happened to end up next to John Cusack. He kept asking her questions because he thought he recognized her before finally exclaiming, "Hellraiser III! You were really good in that!" Marshall was not only very amused that John Cusack had seen "Hellraiser III: Hell on Earth," but was also very touched that someone as famous as John Cusack remembered her first major role.
Trivia: The radio we see Joey find in the dream is actually the exact same radio seen in "Hellbound: Hellraiser II." Not the same make and model... the EXACT same radio. The production designer put an order in for a period-accurate, old-timey radio for the World War I scenes, and through sheer dumb luck, the prop house just so happened to send them the same radio from the previous film.
Trivia: Clive Barker originally had no involvement with the film. He was brought in during post-production to help fix the film, evidently quipping, "Alright, now let's make it into a 'Hellraiser' film!" after seeing a rough cut.
Trivia: The barman at The Boiler Room, and the subsequent cenobite he turns into ("Barbie"), is played by Peter Atkins, the film's screenwriter, in a small supporting cameo role. (Albeit his voice was dubbed over by the director, since Atkins wasn't around during looping, kind of making it a two-part cameo).
Trivia: "Gremlins" star Zach Galligan has a "blink and you'll miss it" cameo as one of the dead bodies in the nightclub after the massacre. He's only on-screen for a second, but if you know where to look, you can see him. (He's impaled with a pool stick.) Evidently the director asked him to make a cameo as they had worked together before on the "Waxwork" films, and Galligan accepted.
Chosen answer: It's a piston. 2 piston rods are jammed through his head and they move powered by something unknown. You can see the crank shaft and part of some sort of cylinder. A piston is part of an internal combustion engine. It's part of his cenobite form since he liked cars.
