This document outlines the conventions of films in the "Devil, Demons and Hell" sub-genre. The plots typically focus on the rituals and exploits of the main antagonist, often the Devil. Characters include the possessed antagonist, a priestly protagonist who defeats the devil, and helpless victims. Settings are usually remote forests for the antagonist and religious places for the protagonist. Camera work employs extreme close-ups and strange angles to depict exploits and create confusion. Soundtracks use religious and cultural music that sometimes clashes with the visuals. Editing features chase sequences with long shots and fast pacing, concluding with close-ups of victims or antagonists.
