It was a rainy Friday night, I was scrolling through horror movie trailers — and then I saw it. A tiny submarine. A blood-red ocean. No stars left in the sky. I shivered. That chilling image still haunts me. And now, that eerie vision is coming to life on the silver screen: Iron Lung is almost here — and if you love horror with a twist of sci-fi, you might want to ready your popcorn.
What is “Iron Lung”?
Iron Lung is an upcoming sci-fi horror film directed by and starring the popular YouTuber Markiplier (real name Mark Fischbach). It’s based on an indie horror video game created by David Szymanski, and marks Markiplier’s feature-film debut — he’s not only acting, but also wrote, produced, and edited the movie.
In the story’s dark, post-apocalyptic universe: after a cosmic catastrophe called “The Quiet Rapture,” all stars and habitable planets vanish. Humanity scrambles. On a bleak moon designated AT-5 lies an ocean — not of water, but of blood. Desperate and reckless, an organization welds a convict into a rickety little submarine (the “Iron Lung”) and sends them into the deadly red depths. Success means freedom; failure means another mission for the next convict.
In short: claustrophobic horror, existential dread, and a submarine teetering on the edge of destruction.
When & Where to Watch
- Theatrical release date: January 30, 2026.
- Where: Not a blockbuster-wide release. The plan is a limited run in about 50 to 100 independent theaters across the U.S., as the film is self-distributed by Markiplier.
- Streaming / digital release: Not confirmed yet. As of now, no streaming platform has been announced; the focus remains on the theatrical run.
If you’re outside the U.S., there’s no guarantee yet that local cinemas will screen it — but horror fans worldwide are keeping fingers crossed.
What Makes “Iron Lung” Special (and Worth Watching)
– From Indie Game to Feature Film
The original video game — a tense, one-room submarine horror experience — earned a cult following for its oppressive atmosphere and unsettling premise. Turning that into a film is ambitious. Many adaptations dilute the source; here, the aim seems to be to preserve the dread and isolation while expanding the story to full cinematic scope.
– A True Creator-Driven Project
Markiplier isn’t just the star. He’s behind nearly every creative decision — writing, directing, editing, producing, and financing. That level of personal investment often leads to bold, unfiltered art.
– Horror + Sci-Fi + Psychological Tension
This isn’t a typical jump-scare flick. It blends horror, dystopian sci-fi, and psychological dread — a dark mix that could appeal to fans of cerebral horror and atmospheric sci-fi rather than just gore or shock value. The “ocean of blood” and claustrophobic submarine set-up naturally evoke fear and existential angst.
– A Potential Horror Milestone
According to early production reports, Iron Lung may claim the record for “most fake blood ever used in a horror movie” — more than what horror classics have done before. That’s a wild detail, but also a hint at the film’s commitment to shock, gore, and raw realism.

What to Do (and What to Know) — Practical Tips for Watching
| Step | What You Should Do / Know |
|---|---|
| 1 | Check if a theater near you is screening it — Since it’s limited to 50–100 indie theaters, find if any local cinema is participating, especially around release weekend (Jan 30–Feb 1). |
| 2 | Book tickets early — Limited screenings could sell out fast, especially with fans of the game and Markiplier. |
| 3 | Expect mature horror — The movie involves blood, horror elements, and disturbing themes; it’s not for faint hearts. |
| 4 | Go in with an open mind — but know the premise — If you experienced the game, don’t expect a one-to-one recreation. Treat the film as its own expanded version. |
| 5 | Watch with the right mood — Dim light, no distractions. Its horror + psychological tension combo works best when you’re properly immersed. |
Common Pitfalls & Mistakes to Avoid
- Expecting a “traditional horror blockbuster.” This is indie, experimental horror — not a wide-release, CGI-heavy film.
- Going without checking the screening list. Since distribution is limited, don’t assume it’ll be showing everywhere.
- Underestimating the horror. The submarine, blood ocean, and existential despair can hit hard — and it’s reportedly very gory.
- Comparing too rigidly to the game. The game’s short runtime and single-room design don’t map perfectly to a 90+ minute film — so don’t expect full fidelity.
Real-World Use Case: Who This Film Is For
- Horror fans who love psychological dread — if you like horror that messes with your head rather than relying on cheap jump-scares.
- Fans of indie games turned movies — if you played the original game and always wondered what it would look like on the big screen.
- Supporters of creator-driven cinema — people who appreciate when digital creators take bold risks to create something out-of-the-box.
- SCI-fi lovers who enjoy dystopian, existential themes — the film’s post-apocalyptic setting and cosmic horror elements might resonate more than a standard haunted-house flick.
Film vs. Game — Quick Comparison
| Feature | In the Game | In the Film |
|---|---|---|
| Perspective | First-person, you pilot the sub | Cinematic, narrative structure, character interactions |
| Duration | 1–2 hours (varies) | ~1 hr 35 min runtime |
| Atmosphere | Claustrophobic, minimal visuals, heavy imagination | Visual horror, cinematic tension, action/character-driven |
| Story Scope | Sparse, mysterious, implied backstory | Expanded plot, dialogue, character arcs, cosmic stakes |
Both have their strengths — as game, it’s intimate and psychological; as film, it has a broader canvas.
Final Takeaway
If you’re looking for horror that breaks the mold — atmospheric, unsettling, sci-fi-tinged — Iron Lung might just be one of the most interesting horror releases of 2026. With its indie sensibilities, creator passion, and willingness to push boundaries, it’s not just a movie: it’s a daring experiment. Whether you’re a fan of the game or a newcomer, give it a shot — but go in prepared.
