Synopsis

The stars are gone. The planets have disappeared. Only individuals aboard space stations or starships were left to give the end a name - The Quiet Rapture. After decades of decay and crumbling infrastructure, the Consolidation of Iron has made a discovery on a barren moon designated AT-5. An ocean of blood.

Moviegoers are saying
Markiplier's ambitious directorial debut divides audiences with its claustrophobic two-hour journey that transforms a one-hour video game into a slow-burn psychological thriller. While some viewers found themselves craving a director's cut with Markiplier reacting in the corner, others praised it as 'absolute cinema' that delivers genuine dread and impressive visual effects for an independent production.

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

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.

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