I just walked out of the theater and honestly, I need a minute. My hands are still a little clammy. 'Iron Lung' isn't just a movie you watch; it's an experience you endure, in the best possible way. I'm sitting here with my coffee, and I can still feel the oppressive weight of that blood ocean, the claustrophobia of that tiny submarine. It's the kind of film that settles in your bones. I keep thinking about the ending—no spoilers—but it left me with this profound, quiet dread that's more unsettling than any jump scare. It's definitely going to haunt my thoughts for a while.

What's Iron Lung About?
The movie is set in a bleak future after a mysterious event called 'The Quiet Rapture' has wiped out most of the stars and planets. Our protagonist, a convict played by Mark Fischbach, is sent on a desperate, one-man mission in a rickety submarine—the 'Iron Lung'—to explore a terrifying, blood-red ocean on a distant moon. It's essentially a high-stakes, deep-sea horror story, but in space. The mission is simple: go down, find answers, try not to lose your mind.
What Works in Iron Lung
- ✓ The suffocating atmosphere is masterful. You feel every creak and groan of the sub, making you part of the crew.
- ✓ Mark Fischbach's performance is a revelation. His descent from grim resolve to raw, whispered terror felt painfully real.
- ✓ The sound design is a character itself. The silence is just as terrifying as the sudden, metallic shrieks.
- ✓ The visual concept of the blood ocean is hauntingly beautiful and utterly unique. It's an image I won't forget.
What Doesn't Work
- ✗ The middle section drags a bit. There's a ten-minute stretch of just staring at sonar blips that tested my patience.
- ✗ Some of the philosophical voice-overs felt a little heavy-handed, like the movie was explaining its own themes to me.
- ✗ The supporting cast, like Elsie Lovelock's mission control, is great but underused. I wanted more of that outside-world tension.
Standout Moments & Performances
There's a moment where the sub's single external light fails, plunging everything into absolute, blood-black darkness. The only sound is the character's ragged breathing. I actually held my breath. Another scene that got me was a simple, quiet interaction over the comms with mission control (Caroline Kaplan). The way a mundane check-in slowly curdles into something deeply wrong was chilling. But the real kicker is the first 'contact' with something outside. No big monster reveal—just a shape, a pressure, and a sense of ancient, indifferent scale that made my skin crawl.

Direction, Music & Visuals
For a directorial debut, Mark Fischbach shows incredible control. He understands that horror lives in what you don't see. The cinematography inside the Iron Lung is brilliantly cramped, using every distorted fish-eye lens to amplify the claustrophobia. Outside, the vast, murky red is terrifying. The score is minimalist—mostly deep, subsonic drones that you feel in your chest more than hear. Troy Baker's voice work as the AI is perfectly sterile and unnerving. It's a technically cohesive package where every element serves that core feeling of isolated dread.

Who Should Watch Iron Lung?
If you love slow-burn, atmospheric horror where the setting is the monster—think 'The Descent' meets 'Moon'—this is for you. It's perfect for viewers who appreciate psychological tension over gore, and sci-fi fans who enjoy a bleak, thought-provoking premise. If you've ever felt a shiver playing a claustrophobic video game like 'SOMA' or 'Alien: Isolation,' you'll connect with this immediately.
Who Might Want to Skip?
If you need fast-paced action, clear-cut answers, or a traditional monster feature, you'll be bored and frustrated. This isn't a thrill-ride; it's a slow, immersive pressure cooker. Also, if you're severely claustrophobic, maybe give this a wide berth—it might be genuinely uncomfortable.
Final Verdict
I absolutely recommend it, but with the right expectations. It's a demanding, immersive mood piece that won't work for everyone. It's more of an experience than a conventional narrative. I wouldn't watch it again next week—it's a lot to process—but I know I'll revisit it in a year or so, like returning to a disturbing but fascinating nightmare. It's flawed, but its successes are so unique and visceral that they outweigh the pacing issues. It sticks with you.
