Teenage Sex and Death at Camp Miasma 2026

Teenage Sex and Death at Camp Miasma (2026) is an American slasher horror film written and directed by Jane Schoenbrun, the filmmaker behind I Saw the TV Glow. Starring Hannah Einbinder, Gillian Anderson and Patrick Fischler, the movie follows a young queer filmmaker who is hired to revive the fictional Camp Miasma horror franchise. Her search for the original film’s reclusive final girl gradually develops into a strange and dangerous collision of desire, obsession, cinematic violence and fantasy.

The film premiered at the 2026 Cannes Film Festival before opening in U.S. theaters on August 7, 2026, through MUBI. Its unusual blend of slasher conventions, romance, dark humor and psychological horror has made it one of the more distinctive genre releases of the year.

Runtime listings vary slightly by database, with Rotten Tomatoes listing 1 hour 46 minutes and the BBFC listing approximately 112 minutes.

Storyline & Plot Analysis

The Teenage Sex and Death at Camp Miasma storyline centers on Kris, an ambitious queer filmmaker given the opportunity to resurrect the fading Camp Miasma slasher franchise. Hoping to give the series new life, Kris becomes determined to bring back Billy, the actress who played the original movie’s iconic final girl.

Billy has since withdrawn from the public eye and lives a secluded life connected to the original camp. When Kris enters her world, the planned horror reboot becomes increasingly difficult to separate from reality.

The relationship between the two women develops against a backdrop of old horror-movie mythology, attraction and psychological unease. The fictional slasher character Little Death also becomes central to the film’s strange mythology, allowing Schoenbrun to play with familiar slasher imagery while questioning what horror, desire and fantasy can represent.

Rather than functioning as a conventional killer-at-camp movie, the film uses the slasher format to explore identity, sexuality, trauma, intimacy and self-acceptance. Its deliberately meta approach makes the fictional Camp Miasma franchise almost as important as the movie being watched.

Production Details & Behind-the-Scenes

Jane Schoenbrun wrote and directed the film, following their acclaimed 2024 feature I Saw the TV Glow. The movie was produced by Dede Gardner, Jeremy Kleiner and Brad Pitt, with Plan B Entertainment, MUBI and Scythia Films involved in the production. MUBI handled distribution.

Eric Yue served as cinematographer, while Graham Mason handled editing and Alex G composed the music. Principal photography took place in British Columbia, including locations around Camp Barnard, which doubled for the fictional Camp Miasma.

One of the film’s most distinctive creative elements is Little Death, the masked supernatural figure from the fictional slasher franchise. Actor Jack Haven plays the character, whose unusual box-like mask was designed to avoid simply copying familiar slasher icons such as Jason Voorhees.
