Trapped in Blood: A Claustrophobic Lunar Dive
13 Mar
Summary
- A man pilots a submarine through a blood ocean on a distant moon.
- The film focuses on dread and atmosphere rather than jump scares.
- It's the directorial debut of YouTuber Mark Fischbach.

The film Iron Lung plunges audiences into a suffocating, claustrophobic experience aboard a rusting submarine. Set against the backdrop of a dead universe after a cosmic disaster known as the Quiet Rapture, the story follows Simon, a convict on a perilous mission.
Piloting a crude submarine named the Iron Lung, Simon's task is to explore a newly discovered ocean of blood on a remote moon. The submarine, equipped with no windows, forces Simon to rely solely on coordinates and instruments.
Simon navigates by entering coordinates and steering the vessel, periodically firing an external camera to capture grainy photographs of the ocean floor. These fleeting images flash on a screen, challenging the viewer to decipher what lurks beneath the surface.
The film excels in building atmosphere through unsettling sounds like rattling pipes and groaning hulls. Fischbach, who also writes and stars, delivers a performance that captures Simon's growing panic as strange occurrences appear in the photographs.
Despite its strengths in cosmic horror and atmosphere, the film grapples with the limitations of its indie game origins. The repetitive nature of Simon's tasks occasionally slows the narrative momentum, though the eerie ambiance remains consistent.
Reportedly made on a modest budget, Iron Lung achieves an impressive quality without appearing cheap. It opts for intimacy and imagination, focusing on a single character in a confined space, making it a unique watch for those who appreciate psychological dread.
