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.

Critics Consensus

A claustrophobic video game adaptation that can veer into just plain stifling, Iron Lung is more interesting for its production than its story, but it conjures enough atmosphere to announce Mark Edward Fischbach as a filmmaker to watch.

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.

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.

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.

Required some homework afterwards as I was not familiar with the game it was based on, but the acting, atmosphere, and cinematography was so engaging, I enjoyed doing the research.

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.

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.

Fantastic entry into cosmic horror. Great sound, cinematography, and atmosphere, and a great big screen introduction to Markiplier. Iron Lung sometimes spends too much time establishing mood and atmosphere with an over-abundance of B-side shots, but is otherwise incredibly entertaining.

More bizarre than thought-provoking, this film devolves from what starts out as a suspenseful one-person survival drama into an incoherent mess of hallucinations and body horror. Any mystery or ambiguity intended to make the audience an active participant or invite reflection ended up just being confusing and indecipherable.

For a first time movie it was well made. The atmosphere was well done. It had me and my partner at the edge of our seats during a few scenes!

Good idea, but pacing was too slow 2nd half of movie. Could have trimmed 10 minutes off the slow and confusing parts and would have improved viewer engagement 5x. More lore would have been wonderful. A little flashback from his life would have created more context to understand his plight. Needed more context to make his act of heroism more of a win for for both he and the audience.
