Iron Lung is an upcoming American science fiction horror film written, directed, produced by, and starring Mark Fischbach (better known by his online name Markiplier) in his feature directorial debut.
Set in a post-apocalyptic future where an event known as "The Quiet Rapture" caused all known stars and habitable planets in the universe to disappear, a convict is sent to search an ocean of blood discovered on a desolate moon, using a poorly-constructed midget submarine nicknamed the "Iron Lung".
