Inside Camp Miasma: The Fake Slasher Franchise That Feels Entirely Real

If you consider yourself a connoisseur of classic slasher cinema yet have never encountered Camp Miasma, you are certainly not alone. The fictional horror franchise, featuring a masked killer terrorizing a summer camp, serves as the narrative centerpiece of the newest feature from director Jane Schoenbrun, known for I Saw the TV Glow.

Beginning with a fictional original release in 1980, the franchise supposedly enjoyed a decades-long run complete with multiple sequels, arcade cabinets, board games, lunch boxes, alarm clocks, and endless bootleg Halloween costumes. To convince viewers that this sprawling pop culture phenomenon actually existed, the production team had to meticulously engineer its entire fake history from scratch.

Production designer Matt Hyland noted the immense scale of the props department, stating that they easily could have spent three years strictly manufacturing merchandise for the fictional universe if given the directive. The real film follows Kris, an ambitious young filmmaker played by Hannah Einbinder, who receives approval to resurrect the long-dormant horror series.

"We probably could’ve spent three years only making stuff for Camp Miasma if those were the marching orders."

Before beginning her reboot, Kris tracks down Billy, portrayed by Gillian Anderson, the legendary final girl from the original 1980 feature who has spent decades living in total seclusion in the woods. Kris attempts to persuade Billy to join the production, sparking an intimate journey centered around shared conversations about sex, horror movies, and KFC.
