Horror sci-fi flick 'Iron Lung' by Mark Fischbach, better known as Markiplier, is finally hitting theatres. Produced, written, directed, edited, and financed by the renowned YouTube creator is based on the 2022 horror game of the same name.

'Iron Lung' hits theatres on January 30, 2026, with Markiplier distributing the film with independent cinemas across the US. At the time of writing, the director has not finalized plans for where and when 'Iron Lung' will be available on streaming. The film has seen a significant production delay after announcing the project in April 2023, marking the end of the film's shooting. Also starring are Troy Baker, Elsie Lovelock, and Rose Kaplan.

Per Markiplier, the official description of the film reads, "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 was discovered 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."

Per a statement to Variety, the YT creator added, "They said it shouldn’t be done. Not that it couldn’t be done, people have made movies before, just that it would be ‘woefully unwise’ to tackle writing, directing, acting, and editing a movie myself. Showed them. My bathroom might be a render farm now, but I can’t wait for people to see the blood, sweat, blood, tears, and blood that went into this movie from everyone involved.” He added that “Iron Lung” holds a world record for the most blood in a horror movie. Or any movie for that matter."

'Iron Lung' releases in select theatres in the US on January 30. Watch this space for more updates on the upcoming film.
