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.

Iron Lung is an immersive experience. It traps the audience in a close, suffocating space, and the sense of terror is palpable and thrilling. It’s a slow-burn horror movie, but it certainly isn’t lacking in scares.

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.

3/5

The cinematic phenomenon of 2026 is less interesting as a movie than as a paradigm shift towards a new era of online-driven passion projects, away from the traditional studio model.

5/10

There is enough visually to respect what Markiplier is able to accomplish. Unfortunately, this movie fails to build its story properly, struggles to maintain momentum, and ultimately feels a bit too repetitive.

Amazing film that slowly pulls you in and grips tighter and tighter as the story unfolds. Glued to the seat throughout. A must-watch.

Great video game movie adaptation. Very one to one with the game. Yes the beginning can be slow but the climax and ending pick it all up. For someone who practically did almost everything himself (besides the team he worked). Mark did a fantastic job for his first big screen project. Love the claustrophobia, love the ambiance, absolutely loved the fear of dread the movie has.
