Prepare to be trapped in a metal coffin with nothing but your fears and a sea of blood. Iron Lung, Markiplier’s directorial debut, is a chilling endurance test that dares to push the boundaries of horror—and it’s not for the faint of heart. But here’s where it gets controversial: is this a groundbreaking leap into filmmaking for a digital creator, or just a novelty act? Let’s dive in.
Imagine a universe where the stars have vanished, the planets are gone, and humanity clings to existence aboard space stations and starships. This is the world of Iron Lung, set after an event known as The Quiet Rapture. Decades of decay have left civilization desperate for resources, leading to a grim discovery on a barren moon called AT-5: an ocean of blood. The Consolidation of Iron launches an expedition, welding a convict into a windowless submarine to explore the depths. Success means freedom; failure means another will take their place. This is the 13th attempt—will it be the last?
And this is the part most people miss: Markiplier’s transition from YouTube sensation to filmmaker isn’t just a career shift—it’s a bold evolution. Following in the footsteps of creators like the Philippou brothers (Talk to Me) and Chris Stuckmann (Shelby Oaks), Mark Fischbach (aka Markiplier) has stepped into the director’s chair with a passion project that’s as ambitious as it is unsettling. Adapted from David Szymanski’s indie horror game, Iron Lung isn’t just a story—it’s an experience. The game’s core mechanic? A submarine with no windows. The film mirrors this brilliantly, forcing both the protagonist and the audience into a world of blindness and dread.
Let’s address the elephant in the room: does Iron Lung rely on the game’s fanbase to succeed? Not at all. The film stands on its own, thanks to its suffocating set design, masterful soundscapes, and a record-breaking amount of fake blood (yes, it’s as impressive as it sounds). The blood isn’t just a gimmick—it’s the environment, oppressive and ever-present, adding a layer of body horror that’s impossible to ignore. The lighting, too, deserves a standing ovation, embracing a grimy, analog aesthetic that feels more Alien: Isolation than Five Nights at Freddy’s.
But here’s the controversial bit: While Markiplier’s performance is surprisingly grounded, shedding his high-energy YouTube persona for a shaky, desperate survivor, the pacing may test your patience. At times, the film feels like a slow burn that could’ve been trimmed by 20 minutes. Yet, this deliberate pace is intentional, forcing you to feel the weight of time, repetition, and paranoia. Is it hypnotic dread or a missed opportunity? That’s for you to decide.
What’s undeniable is the technical prowess on display. The cinematography, sound design, and Andrew Hulshult’s industrial score create a nightmare that lingers long after the credits roll. And Markiplier’s commitment to the craft is undeniable—writing, directing, financing, editing, and starring in the film without letting it become an ego project. This isn’t YouTuber acting; it’s raw, gritty survival.
So, is Iron Lung worth your time? If you’re craving a claustrophobic, experimental horror experience à la Buried or Locke, absolutely. But if you’re expecting jump scares or a fast-paced thrill ride, you might walk away disappointed. For Markiplier’s fans, it’s a must-see—but what’s truly impressive is how he’s crafted a film that doesn’t pander to them. No winks, no cameos, just a serious descent into the depths of a blood-soaked ocean.
Now, I want to hear from you: Is Iron Lung a bold step forward for digital creators in filmmaking, or does it fall short of its ambitions? And how do you feel about the pacing—hypnotic or too slow? Let’s debate in the comments!**
