20 Horror Movie Characters We NEVER See

1974's Black Christmas doesn't get nearly enough credit for being one of the earliest and most innovative slasher films, nor for featuring such a terrifying antagonist despite the fact that we never get a clear look at him.

The film follows a group of sorority sisters who are stalked and killed by a shadowy man known only as "Billy" (Nick Mancuso), whose face and body are never conclusively shown to the audience.

Director Bob Clark does a fantastic job of blanketing Billy in shadow, such that we never see more than a limb or an eye peering out of the dark. 

This, combined with the character's lack of a clear motive, makes him stand out among slasher film antagonists, leaving him something of a blank slate for audiences to project their own fears and anxieties onto.

Though his lack of palpable screen presence has made him less iconic than, say, Michael Myers, and probably explains why Black Christmas 2 never happened, it's ultimately an artistic choice that's aged incredibly well more than 50 years later.
