The document discusses several technical aspects used in the film Halloween to build suspense and scare audiences. Sound is used to build tension, with ominous music playing when characters are alone and a screeching noise cueing violence. The suburban setting and school playground conform to horror conventions by providing vulnerable settings. Representation follows conventions like innocent female victims and an initially innocent-seeming killer whose identity remains hidden. Genre conventions include an indestructible killer, mystery phone calls, nighttime scenes, and a knife as the killer's weapon.
