Ok. If you don’t know who Markiplier is, you may want to check out his YouTube page. To put it plainly, Markiplier is one of the internet’s favorite content creators. Why is this important? Well, it is pretty easy to promote a horror movie when you have roughly 40 million active subscribers.

Now, Markiplier recently announced that he would be self-funding and self-releasing a horror movie titled Iron Lung. Within a week, the final trailer for the film was released, and it looks awesome. We are talking about blood seeping from the walls, awesome. The film will be based on the hit indie game Iron Lung, created by David Szymanski.

Iron Lung

“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.”

Markiplier is currently working with independent theaters in the United States to release the film on January 30th, 2026. Markiplier seems very confident in the film. Going so far as to state that Iron Lung will have the “most blood in a horror movie. Or any movie for that matter.”
