History YMMV / Deranged

** [[MrExposition Simms]]' actor Les Carlson would later gain fame in horror circles for his role as [[BigBad Barry Convex]] in ''Film/{{Videodrome}}''.

** Co-director Jeff Gillen later played the memorably grumpy MallSanta in ''Film/AChristmasStory''.

* SugarWiki/HeReallyCanAct: While Creator/RobertsBlossom's talent was never in doubt, it's here in his only leading role that he really gets to shine as an actor with his legitimately unsettling (though oddly pathetic) portrayal of Ezra.

** The film features some early work by Creator/TomSavini, who later went on become one of the most revered make-up artists in film history.

** Alan Ormsby, meanwhile, would later go on on to write the scripts for such films as ''Film/CatPeople'', ''Film/{{Porkys}} II'', and ''Film/{{Popcorn}}''.

* NightmareFuel: While there is the occasional bit of BlackComedy to lighten the mood, the film as a whole still possesses a very creepy and disturbing atmosphere, particularly in the scene where Ezra kidnaps Mary and tries to force her to "marry" him. To say nothing of Creator/RobertsBlossom's genuinely unnerving performance as Ezra.

* MoralEventHorizon: Ezra was already a rather unnerving presence with his [[DesecratingTheDead corpse desecration]] and obsession with his deceased mother, though one could argue that at least he wasn't harming any living being. His AttemptedRape and subsequent killing of Mary, however, marks the point of no return for him.
