Markiplier's feature film debut Iron Lung is about to hit home release on the creator's platform of choice: YouTube.
The 36-year-old creator and streamer also known as Mark Fischbach pivoted to filmmaking in the last few years, with his first feature-length horror movie released in cinemas in January to colossal success. Written, directed, edited, and starring Fischbach, and based on David Szymanski's 2022 post-apocalyptic horror game, Iron Lung made Sam Raimi's marooned horror Send Help sweat at the box office — and it even saw an extended theatrical release.
Now, Iron Lung will be available for to rent or buy on YouTube Movies on May 31, with a global rollout expected. The news was announced (of course) on YouTube by Markiplier on Sunday.

"I don't know if it'll make much of a difference, but hey, at least I'll be in a position that I could do something about something, and that's a position that I wouldn't have been in if it wasn't for you guys.
