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.

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.

Now you may ask ... How are they making new oxygen? Doesn’t blood congeal or separate or something? how did they fine this moon without light? shut up nerd, Markilpier’s in a sub, now sit back and be scared.

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.

Big highlights from the movie were fantastic looking practical VFX, great VO work, and the feeling of delirium and sanity slippage from the main actor. It did a great job keeping your heart rate up throughout the movie. I did not play the video game so I can't compare it directly but from what I know about it, the movie seemed to honor the core themes (isolation, hopelessness, entombment, blood).

I'd recommend this movie to anyone that enjoyed the game as it handled the original with the respect it deserves. And even if you've never played Iron Lung, I'd recommend this film to those that appreciate slow-burning cosmic horror. I am so incredibly proud of Mark, what he's created, and how much he's grown. 10 outta 10 would watch again.

Quality blood scenes although I felt it was a bit drawn out before the action in the end

I went because my son wanted to, I really didn’t think I was going to like it but it was pretty good. I gave it four stars because I didn’t like the end.

I thought it would get boring because of the long run time. But it didnt! I actually enjoyed it so much more than i thought i would. Loved the ending. My friend was absolutely petrified, I didnt think it was that scary.

The movie was always keeping my heart rate up. It wasn’t about all the jump scares it had me thinking “what is going on and what will happen next!”
