* ActorAllusion: Doc Frasier (who is played by Creator/DougBradley) of ''Ashes to Ashes'' has [[Franchise/{{Hellraiser}} puzzle boxes]] scattered about his office.
* ColbertBump: The series as a whole got ''much'' more attention after WebVideo/TheSpoonyExperiment did a review of the second movie's ... interesting... video game adaptation.
* DoingItForTheArt: Creator/LanceHenriksen bought a bunch of stuff from pawn shops and thrift stores based on his visions of what Ed Harley should be like (from the WWI shotgun that he used to the clothes that he wore to the silver dollars he initially tried to pay Haggis with), asked the makeup department to make him some false teeth to make him look like he had never been to a dentist in his entire life, and even bought Matthew Hurley (the kid who played Ed's son, Billy) a pet bunny so that he could be viewed as trustworthy and thus create authentic on-screen chemistry.
* WhatCouldHaveBeen: Apparently, the second film was supposed to feature a winged Pumpkinhead (which would probably help explain the subtitle, ''Bloodwings'' ).
