11. Black Christmas (1974)
One of the earliest slasher films, Black Christmas, set the stage for future genre conventions. Following a sorority under siege by a mysterious killer during the holiday season, the film introduced tropes like the stalker’s voice over the phone and the “final girl” archetype. Its tense atmosphere, confined setting, and psychological terror created a blueprint for Halloween and other slashers.
The movie influenced countless holiday-themed horrors and remains notable for its chilling suspense rather than overt gore. Its cultural impact persists, cementing it as a foundational work in slasher cinema.
