!!The first film:
* During the production of the first film, Barker asked the production team for a suitable name after the original novel title ''The Hellbound Heart'' was rejected by execs. One older lady suggested ''What a Woman Will Do For a Good Fuck''.

!!Other
* When Leviathan manifests in the comics, he appears uncannily like [[Webcomic/RedMeat Milkman Dan.]]
* Pinhead's dry as sand humor can be worth a few giggles. Doubly so cause it usually follows [[MoodWhiplash scenes filled with hooks and gore]].
