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.

The movie is not quite the Cronenbergian nightmare the director wants it to be. Yet I found myself charmed by Iron Lung’s shagginess; I haven’t seen anything quite like it.

2/5

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.

It shows just how much can be done by a single actor on a single set with the a filmmaker full of determination.

Markiplier’s single-setting sci-fi horror is a technically impressive but lengthy video game adaptation.

This movie makes you question everything while still holding onto that little glimmer of hope. The hope that you can escape this eternal damnation. Overall a fantastic movie and quite frankly it amazes me that a YouTuber has made the best movie of the year so far. Everything else just isnt worth watching right now.

Great effort by Mark in the lead. Not much story to follow, hard to understand the dialog.

I'm not normally a horror person. My nephew wanted to see this, so I took him and we both were on the edges of our seats the whole movie. It was very entraining and Markiplier is justified in his joy at having pulled this success off.
