Film ThreatMikal CgFeb 26, 2026
It shows just how much can be done by a single actor on a single set with a filmmaker full of determination. Read full review

Iron Lung is an immersive experience. It traps the audience in a close, suffocating space with Simon and the seeming inevitability of his death, and the sense of terror is palpable and thrilling. It’s a slow-burn horror movie, but it certainly isn’t lacking in scares. Read full review

The A.V. ClubSimon AbramsFeb 6, 2026
As a performer, Fischbach’s frantic performance can sometimes be distractingly monotonous, but as a filmmaker, he has an impressive eye not only for compositional details, but also for how his images cut and flow together. Read full review

RogerEbert.comZachary LeeFeb 4, 2026
A grungy, blood-soaked DIY chamber piece based on David Szymanski’s 2022 video game of the same name, it’s admirably restrained, being far more interested in creating a haunting ambience than raising your blood pressure. Read full review

Iron Lung is far from a perfect movie, and the pacing ultimately makes the conclusion feel exhausting rather than exhilarating or shocking. You'll be ready to leave once the credits roll. Yet, the craftsmanship is there; with his directorial debut, Fischbach shows that he's more than just a YouTuber, and he can conjure up the same kinds of scares that make him scream as he's playing games.

Iron Lung is audacious and at times astonishingly boring. Still, it feels more enthusiastic and celebratory than many blockbuster adaptations built on safer math. Read full review

Despite Fischbach’s arguably admirable intent and exertion, this low-budget sci-fi horror makes Event Horizon look like 2001: A Space Odyssey. Read full review

The GuardianMike McCahillFeb 2, 2026
Many of us have long sensed culture is making a decisive break with the analogue in favour of the (perhaps terminally) online and Fischbach’s film makes that paradigm shift not just visible but visceral; it feels not unlike spending 12 hours on Twitch with all the curtains closed. Read full review

IGNEric GoldmanJan 30, 2026
Iron Lung has terrible pacing and very low energy from the start. The scenarios that Fischbach has put his character in just aren’t compelling enough to watch unfold, with scenes that drag on and on. Read full review
