Thescreescore – Gillian Anderson, an actress synonymous with groundbreaking roles and critical acclaim, has once again captivated the cinematic world. Her latest venture into the horror genre, Teenage Sex and Death at Camp Miasma, has premiered to an unblemished 100% critics’ score on Rotten Tomatoes, marking a significant triumph for the film and its star. This perfect aggregation comes after the movie’s global unveiling at the prestigious 2026 Cannes Film Festival, maintaining its flawless rating across 36 professional reviews, a testament to its immediate impact.
Anderson, celebrated for her indelible portrayal of FBI Special Agent Dana Scully in the seminal sci-fi drama The X-Files – a role that garnered her an Emmy – and her more recent Emmy-winning turn as Margaret Thatcher in Netflix’s The Crown, brings her formidable talent to this new, chilling narrative. Her diverse filmography also includes acclaimed performances in Hannibal, Sex Education, and the upcoming The Abandons.

Teenage Sex and Death at Camp Miasma, a 112-minute feature helmed by writer-director Jane Schoenbrun, plunges viewers into a darkly comedic and unsettling world. The plot centers on Kris, a queer director brilliantly played by Hannah Einbinder (Hacks), who is tasked with revitalizing the flagging Camp Miasma slasher franchise. To achieve this, Kris enlists the original film’s star, Billy Preston, portrayed by Anderson, a decision that spirals into terrifying and unforeseen consequences. The ensemble cast further boasts impressive talents, including Zach Cherry (Severance), Sarah Sherman (Saturday Night Live), Jasmin Savoy Brown (Yellowjackets), and veteran character actor Patrick Fischler (Mad Men).

Critics have lauded the film for its unique vision and compelling performances. Katie Riff of Inverse hailed it as "a highly personal work, a defense of problematic favs, and a movie that only Jane Schoenbrun could make." Siddhant Adlakha, writing for Decider, echoed this sentiment, noting Schoenbrun’s audacious approach: "There’s nothing quite like engaging with the forbidden head-on, which Schoenbrun does by framing the very act of filmmaking as a psychosexual ritual — an urge akin to a serial killer’s murder spree." The performances of the lead actresses have also garnered significant praise, with Stephanie Zacharek from Time magazine describing Anderson’s portrayal of a "1990s scream queen turned glamorous, eccentric recluse" as "sublime," adding that her co-star Hannah Einbinder "keeps pace with her every minute."
This latest film is the concluding chapter in what has been dubbed Schoenbrun’s "Self-Induced Hallucination" or "Screen Trilogy." While not direct narrative sequels, the films – which include 2021’s We’re All Going to the World’s Fair and 2024’s I Saw the TV Glow – are thematically linked by their exploration of queer identity and the intricate relationship between individuals and various forms of media. We’re All Going to the World’s Fair delved into a teenager’s connection with the internet, followed by I Saw the TV Glow‘s focus on a Buffy the Vampire Slayer-esque television series, serving as a poignant allegory for transgender identity. Now, Teenage Sex and Death at Camp Miasma scrutinizes the impact of a long-running slasher franchise.
The trilogy has consistently received critical acclaim. We’re All Going to the World’s Fair achieved a "Certified Fresh" 91% on Rotten Tomatoes, while I Saw the TV Glow earned an 85% "Certified Fresh" rating. Audience reception, however, has been more varied, with World’s Fair registering a 28% Popcornmeter score compared to I Saw the TV Glow‘s more robust 71%. With its current 100% critical score, Teenage Sex and Death at Camp Miasma stands as the trilogy’s most critically lauded installment to date, though this figure may evolve as more reviews emerge.
Distributed by Mubi, a departure from its predecessors’ distributors (Utopia and A24 respectively), Teenage Sex and Death at Camp Miasma is poised to make its theatrical debut on August 7, 2026. Film enthusiasts and horror aficionados alike are eagerly anticipating the opportunity to experience this perfectly rated cinematic event firsthand, a testament to Schoenbrun’s distinctive voice and Anderson’s enduring star power.
