Iron Lung is a 2026 American independent science fiction horror film written, edited, and directed by Mark "Markiplier" Fischbach. It is based on the 2022 video game by David Szymanski. It stars Markiplier, Caroline Kaplan, Troy Baker, Elsie Lovelock, Elle LaMont, Mick Lauer, Seán McLoughlin (Jacksepticeye), Isaac McKee and Alanah Pearce. The plot follows a convict named Simon (Markiplier) who is forced to pilot a submarine through an ocean of blood on a desolate moon following an apocalyptic event known as the "Quiet Rapture" that caused all the stars and most planets along with their human inhabitants to disappear without warning.
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.
