YouTuber-turned-director Markiplier adapts his own video game adaptation into a feature that defied every expectation � a genuinely harrowing, inventive horror film that opens as a body-horror experience and becomes something far more disturbing.

From YouTube to Cinema

Mark Fischbach (Markiplier) is one of YouTube's most successful creators, best known for gaming content. His directorial debut, based on the indie horror game Iron Lung, was treated as a curiosity by mainstream media and dismissed by many film critics ahead of release. The $17.8M opening weekend changed the conversation immediately � and the subsequent critical re-evaluation has been remarkable, with many acknowledging that Fischbach has made something genuinely accomplished: a claustrophobic horror film set inside a submarine sub-vehicle exploring a moon of blood, where the horror is less what's outside than what being trapped inside does to the human mind.

"Iron Lung is a serious horror film and Markiplier is a serious director. Anyone who doubted this owes themselves an admission of error and a viewing."

The Verdict

$52M worldwide on an indie budget from a YouTuber's directorial debut. Cinema is still full of surprises, and this is one of the best. A remarkable achievement and a genuinely terrifying film.
