- The prologue where Frank Cotton opens the Lament Configuration. The scene is much longer for one, and contains some very surreal imagery, such as the repulsive "offerings" Frank has gathered for the Cenobites: A box of chocolate, a jug of his own urine and dove heads among other things. The Cenobites also dont just claim Frank and drag him off, after he agrees to accompany them we're treated to a scene where Frank experiences massive sensory overload, ending with him climaxing on the floor. Finally, once he regains his bearings, he's met with the Female Cenobite, sitting naked on a pile of rotting human heads, with their tongues cut out and meticulously placed on her spread thighs, which we're given a detailed description of how her genitals have been mutilated and flayed.
- When Rory cuts himself and bleeds on the floor in the attic room, Frank doesn't just re-materialize. The reader (and Julia) are shown exactly what happened to Frank after he was dragged off to the Cenobite realm: he's now in a Sealed Room in the Middle of Nowhere connected to the attic room, in a hideously mutilated state, his skin gone, missing an eye, all his nerves exposed, and the only reason Rory's blood brought him back was because Frank had left something of himself behind (his semen) for the blood to react to.
- Julia's death is a good deal worse. She's accidentally stabbed by Frank like in the movie, but rather than being bound to a bloody mattress with hooked chains before being drawn into the Cenobite realm, Kirsty finds her sitting in the kitchen wearing her wedding dress... only for Kirsty to realize that Julia's voice isn't coming from behind the veil, but from her lap. The headless body is clutching the still-living head of Julia, who begs Kirsty for help, only for a glow from behind the wedding veil interrupt her - the book version of The Engineer, who is possessing the body.
- The Cenobite world is never shown in any detail in the book, but is referred to as a "realm of black birds", giant wings flapping in an eternal tempest. Somehow that abstract image is a lot worse than the hellish realm from Hellbound: Hellraiser II.
Nightmare Fuel / The Hellbound Heart
The Hellbound Heart has quite a few nightmarish scenes that wasnt used in the Hellraiser movies. Of note are:
