Plot Summary: Descent Into an Ocean of Blood
Iron Lung takes place after a mysterious cosmic disaster known as “The Quiet Rapture”, an event that caused entire star systems and planets to vanish. Humanity is left scattered and desperate for resources.
The story follows Simon, a convicted prisoner forced into a suicidal mission: exploring an ocean of blood on a desolate moon inside a rusted submarine called the Iron Lung. His task is to photograph and collect data from the depths—knowing full well that no one expects him to survive.
Inside this sealed metal coffin, Simon slowly descends into isolation, paranoia, and hallucinations. Guided only by a grainy camera and a distorted intercom voice, he must confront both external horrors and his own fractured past.
Rather than explaining everything clearly, the film deliberately leaves many questions unanswered—turning confusion into part of the experience.
Atmosphere and World-Building: Horror Through Restraint
One of Iron Lung’s greatest achievements is its atmosphere.
Almost the entire movie takes place inside one cramped room. Yet, it never feels visually boring.
What Works Exceptionally Well:
-
Rust-covered submarine interior
-
Flickering lights and leaking pipes
-
Monochrome camera system
-
Constant oxygen meter on screen
-
Minimalist UI inspired by video games
These elements quietly remind you that time is running out.
The film turns simple mechanics—like taking photos or checking oxygen—into sources of dread. You feel the pressure of millions of tons of blood surrounding the vessel, even though you rarely see it directly.
The monster, when present, is mostly implied. This restraint makes it far more unsettling than flashy CGI ever could.
Mark Fischbach’s Performance: Surprisingly Strong
Let’s be honest: watching a famous YouTuber in a serious horror film comes with expectations—and skepticism.
Surprisingly, Mark Fischbach delivers a genuinely committed performance.
His Strengths:
-
Emotional breakdowns feel raw
-
Panic and desperation feel believable
-
Physical exhaustion is convincing
-
He sells isolation extremely well
When Simon starts losing his grip on reality, Mark’s acting becomes the emotional backbone of the film. In several scenes, you forget you’re watching “Markiplier” and start seeing only the character.
Where It Falls Short:
-
Some dialogue sounds rehearsed
-
Occasional overuse of profanity
-
A few emotional beats feel undercooked
Still, for a self-financed debut feature, this is an impressive effort.
Direction and Cinematography: Making Small Feel Huge
Director Mark Fischbach shows a strong visual instinct.
The camera work constantly shifts between:
-
Tight claustrophobic close-ups
-
Distorted wide-angle shots
-
Low-angle perspectives
-
Fish-eye lenses
This creates an unsettling rhythm—oscillating between confinement and brief moments of “space.”
The editing is precise, especially during moments of psychological collapse. Hallucinations, distorted audio, and overlapping voices blur the line between reality and imagination.
Even though the movie reuses certain setups, it rarely feels lazy. Instead, it reinforces the feeling of being trapped.
Pacing: Slow Burn That Divides Audiences
Iron Lung is unapologetically slow.
For some viewers, this is its greatest strength. For others, its biggest weakness.
Why the Slow Pace Works:
-
Builds immersion
-
Enhances dread
-
Rewards patience
-
Encourages interpretation
Why It Frustrates Some Viewers:
-
Long stretches with minimal dialogue
-
Slow exposition
-
Occasional audio clarity issues
-
Plot can feel vague
Personally, I appreciated the commitment to slow storytelling. In an era of short attention spans, this film dares you to sit with discomfort.
Psychological vs. Body Horror: A Divided Third Act
The film shines brightest in its psychological horror segments.
The second act, where Simon begins hearing voices and reliving fragments of his past, is especially powerful. There’s even a surreal sequence reminiscent of 2001: A Space Odyssey that feels like the perfect ending.
Unfortunately, the third act shifts toward body horror, which feels less organic.
Issues in the Final Act:
-
Abrupt tonal shift
-
Confusing motivations
-
Oxygen meter inconsistency
-
Underwhelming final shot
Instead of a haunting conclusion, the movie ends somewhat suddenly. It’s not bad—but it’s not as impactful as it could have been.
Themes: Sacrifice, Exploitation, and Human Desperation
Beneath the horror, Iron Lung explores serious themes:
-
Corporations exploiting expendable workers
-
False promises of “calculated risk”
-
Loss of agency
-
Survival vs. dignity
-
Institutional betrayal
Simon is treated as a disposable asset, not a human being. His growing anger reflects a system that preaches morality while practicing cruelty.
In many ways, the story mirrors real-world labor exploitation—just wrapped in cosmic horror.
Indie Spirit and Industry Impact
What makes Iron Lung special isn’t just the film itself—it’s how it was made.
-
Self-financed
-
Independently produced
-
No major studio backing
-
Creator-driven vision
Despite this, it performed strongly in theaters, competing with larger releases. That alone is a statement.
It proves that passion projects can still find audiences in a studio-dominated industry.
