Iron Lung, the debut feature film from successful YouTuber Mark Fischbach, will be available to watch on YouTube from May 31, reports Deadline. Fischbach, who is known to his YouTube viewers as Markiplier, revealed the film’s home viewing premiere date during a panel discussion at Cannes.

It was confirmed the release will be exclusive to YouTube, with Fischbach referring to the service as his home.

“I’m pretty loyal to it,” he said.

Iron Lung, which was written, directed, and edited by Fischbach (who also self-financed and starred in the film), was released in cinemas in January this year. Based on the 2022 video game by developer David Szymanski (Dusk, Gloomwood), Iron Lung is the story of a convict who is sealed inside a submarine and forced to navigate his way through an ocean of blood on a desolate moon. The mission comes in the wake of an unexplained phenomenon that has seen all stars and planets in the universe disappear, leaving the only humans remaining those who were aboard space stations or spacecraft at the time.

While the critical response to Iron Lung was mixed, the film was a commercial success, grossing more than $50 million on a budget of $3 million. IGN’s review noted that while it was clear Fischbach “really loves Iron Lung… his sluggish movie adaption of the game feels interminable rather than serving as a compelling interpretation of this world.”
