Markiplier’s big screen horror debut rolls into theaters

Internet creators jumping into film usually triggers skepticism, and honestly, it should. But Markiplier stepping into theaters with Iron Lung feels different. This is not a brand extension or a content pivot. It is a self-financed horror film based on a game that already understood dread better than most big studio releases.

Iron Lung thrives on claustrophobia, isolation, and implied terror, the same ingredients that made games like Amnesia and SOMA linger in people’s heads. Translating that to film is risky, but horror has always been the genre where outsiders break in successfully. Look at how filmmakers like Mike Flanagan or even Sam Raimi started by pushing fear first and polish second.

What’s interesting here is the focus on practical scares and suffocating atmosphere instead of digital spectacle. That puts Iron Lung closer to minimalist sci-fi horror like Cube or Moon than flashy franchise fare. Whether it fully works or not, this is a legitimate attempt at cinema, not influencer cosplay.

If this lands, it could quietly open the door for more game-driven horror projects that understand fear as an experience, not just a plot device.
