Mark Fischbach has set a date for the next phase of Iron Lung: the movie will launch exclusively on YouTube as a paid purchase on May 31, 2026. He also said he plans to step away for at least one year after finishing the nonstop grind of making and releasing the film.
That makes the release a fresh destination for fans of Markiplier, whose YouTube audience helped turn a low-budget creator project into a box-office story that few saw coming. Fischbach called YouTube a place he remains loyal to, and the platform is now where viewers will be able to buy the film after its theatrical run.
Iron Lung is based on the stripped-down indie horror game by David Szymanski, and the movie follows a lone prisoner trapped inside a rusted submarine drifting through an ocean of blood on a dead moon. Fischbach personally financed the film with a reported $4 million budget, then watched it pull in $17.8 million domestically in opening weekend without traditional marketing and cross $50 million worldwide by the end of its theatrical run.
That success was never a certainty. Before the movie arrived, the project drew skepticism because the game it came from was so spare and Fischbach had never directed a feature before. The run changed that calculus, especially once the film found an audience that already knew him from YouTube and did not need a studio campaign to tell them where to look.
Fischbach did not frame the YouTube release as a farewell, but he did leave one important question hanging after the Cannes Film Festival panel: what he will work on next. He said, “Next year I’ll be working on something,” but did not say what it is. For now, Iron Lung is the project with a date, a platform and a finish line, while the next chapter stays off camera.
