Teenage Sex and Death at Camp Miasma

THE FINAL GIRL ISN'T FINISHED YET

The Camp Miasma franchise has a problem.

Nobody cares anymore.

After years of increasingly slapdash sequels and fading fandom, the fictional slasher series is ready for the treatment Hollywood gives so many pieces of exhausted intellectual property:

Resurrect it.

In Jane Schoenbrun's Teenage Sex and Death at Camp Miasma, that resurrection is handed to an enthusiastic young director. But her attempt to revive the franchise leads her away from the machinery of the remake and toward the mysterious actress who starred in the original film—the woman who once played its final girl and has since withdrawn from public life. 

Hannah Einbinder plays the filmmaker. Gillian Anderson plays the reclusive star.

And somewhere between them is Camp Miasma itself.

That's an important distinction because Camp Miasma isn't a real forgotten slasher franchise. Schoenbrun has invented one, complete with the accumulated mythology, sequels, fandom and baggage of a horror series that feels like it could have occupied video-store shelves for decades.

The construction gives Schoenbrun a way to play with the slasher from the inside.

This isn't simply a movie borrowing the imagery of old horror films. It's about what happens when people grow up with those images lodged inside them—and then attempt to remake them.

For Schoenbrun, that relationship with horror goes back much further than this movie. In interviews surrounding the film, they have discussed growing up making homemade slasher movies and writing fan fiction. Talking about Camp Miasma at Cannes, Schoenbrun connected the new film to a different emotional point in their life and work: making something concerned with feeling good in one's body rather than remaining trapped entirely within shame. 

That change matters.

Schoenbrun's previous features, We're All Going to the World's Fair and I Saw the TV Glow, also examined the strange power media can acquire over identity. But Camp Miasma approaches that relationship through a different cinematic language—bloodier, funnier, more overtly sexual and deliberately tangled up in the pleasures of genre.

Schoenbrun has spoken explicitly about the slasher's historical collision of sex and violence. In discussing the film, they described that confusion as central to the genre while also acknowledging something much less academic:

Sometimes watching a slasher is simply fun. 

Camp Miasma refuses to choose between those ideas.

It can interrogate the genre and enjoy it.

It can question an old movie while loving it.

It can recognize the ugliness buried inside a piece of pop culture without pretending that recognition automatically destroys the attachment somebody formed to it years ago.

And then there's the final girl.

Horror has spent decades asking what happens to the woman who survives until the credits.

Schoenbrun asks something slightly different:

What happens after everyone else stops watching?

The answer brings Einbinder's filmmaker and Anderson's former star together in the strange space between fan and icon, filmmaker and subject, past and remake. MUBI describes what follows as a world of “desire, fear, and delirium”—a useful description because conventional reality becomes increasingly inadequate for what Schoenbrun is doing. 

The film itself arrived with its own unusually prestigious horror pedigree.

Teenage Sex and Death at Camp Miasma premiered at the 2026 Cannes Film Festival, where it screened in Un Certain Regard. Cannes officially lists Schoenbrun as both director and screenwriter, Eric K. Yue as cinematographer, Graham Mason as editor and Alex G as composer. 

MUBI brought the film to U.S. theaters beginning August 7, 2026. After opening in a handful of theaters, it expanded nationwide on August 21 and ultimately crossed the thousand-theater mark. 

And as of September 12, the camp still hasn't closed.

The film remains in theatrical circulation, with independent theaters continuing to schedule screenings into mid-September. 

Which feels appropriate.

Because Teenage Sex and Death at Camp Miasma is built around something horror fans understand better than almost anyone:

A franchise can die.

A movie can disappear.

An actress can walk away.

The audience can move on.

But put the right tape back in the machine, and suddenly the lake is moving again.

Something down there remembers you.
