The stars are gone. The planets have disappeared. Only individuals aboard space stations or starships were left to give the end a name -- The Quiet Rapture. After decades of decay and crumbling infrastructure, the Consolidation of Iron has made a discovery on a barren moon designated AT-5. An ocean of blood. Hoping to discover desperately needed resources they immediately launch an expedition. A submarine is crafted and a convict is welded inside. Due to the pressure and depth of the ocean the forward viewport has been encased in metal. If successful, they will earn their freedom. If not, another will follow. This will be the 13th expedition.

What to Know

Audience Says

A psychological descent that keeps hope out of reach, Iron Lung may be a slow burn, but its mood and atmosphere still leave a lasting scorch.

Despite Fischbach’s arguably admirable intent and exertion, this low-budget sci-fi horror makes Event Horizon look like 2001: A Space Odyssey. Go to Full Review
Rebecca Onion Slate Feb 6
Some sequences work better than others, but to his credit, Markiplier does deliver the intensity needed at the end, when Simon makes a desperate and impressively gruesome sacrifice. Go to Full Review
Keith Uhlich (All (Parentheses)) (Substack) Feb 6
Markiplier’s lugubrious mo-pic is vanity project Tarkovsky with a soupçon of early Ridley Scott, and hell’s bells if that hodgepodge isn’t more-often-than-not impressive and effective. Go to Full Review
Patrick Beatty ABC4 Utah 1d
The middle is a bit meandering, but for a first-time filmmaker who also wrote, starred in, and edited, this is an admirable first entry in what could be a bright career. Go to Full Review

Ultimately, Iron Lung ended up being a valiant effort that just wasn't strong enough to hold my attention, I hope Fischbach and company prove me wrong with their next project, if there ends up being one at all. Go to Full Review
Matt Hudson Bloody Awesome Movie Podcast 3d
It's flawed narratively and far too long, but it has plenty to admire, strong visuals and Fischbach shows real promise as the creative force behind the project. Go to Full Review

Justin 2h The film was a good start for Markiplier, but he has some room for improvement. The first act went well, but the second act was incoherent. The tension was there, and the thrill intense, but the backstory was paper thin, and the ontology of the film was incomprehensible. In essence, the pacing was good, but the metaphysics was lacking, leading to major plotholes. Mark, if you’re reading this, please patch them up, and you’ll have a better movie. See more TheNerdMichael 3h For Markiplier and his team, this is a great first outing as a film. Great use of a limited set, existential themes, and plenty of blood and spookiness. Sometimes a bit corny and a lil underveloped with its long run time, I still appreciate the adaptation of a 15 minute long game. See more Trevor 5h the movie itself was good, but definitely check if the theater you're seeing it at has 7.1 surround sound. the dialogue is SUPER quiet on 5.1 sound systems, and lots of theaters have 5.1 setups. See more Zachary H 6h I commend Markiplier for actually making it and getting to a wide theatrical release. This is clearly a passion project for him….but it’s very flawed. Terrible pacing, confusing last 15 minutes, abrupt ending….and frankly a horror movie that’s not very scary. Very atmospheric with the limited space, but that can only create so much tension. But even that tension is quickly gone due to the unnecessarily long 2 hr run time. See more Amanda 22h A true passion project. A slow-burn thriller rather than a jumpscare filled horror. See more Joshua 22h This is an Absolute must-see the acting 10/10 the special effects and practical effects 10/10. On the edge of my seat the whole time!! See more Read all reviews
