Markiplier’s horror film Iron Lung has passed $50 million in worldwide box-office grosses. The exact total depends on the database: Box Office Mojo reported $50,036,487, while The Numbers reported $51,226,173 when their pages were accessed in 2026. Neither figure should be treated as an undisputed final total.
How much has Iron Lung made?
The two box-office databases agree that the film is above the $50 million mark, but report different domestic, international and worldwide totals. Their pages do not explain the discrepancy, so the figures should remain attributed rather than averaged.
| Source | Domestic gross | International gross | Worldwide gross |
|---|---|---|---|
| Box Office Mojo (accessed 2026) | $40,851,941 | $9,184,546 | $50,036,487 |
| The Numbers (accessed 2026) | $41,111,208 | $10,114,965 | $51,226,173 |
The difference between the reported worldwide totals is $1,189,686. Each total is a database snapshot, not a reconciled accounting statement.
What was its opening weekend?
Box Office Mojo lists a domestic opening of $17.8 million. The Numbers reports an opening weekend of $18,190,786 across 3,015 theaters, equal to 44.2% of the domestic gross in that database’s figures. Those opening figures differ as well, so each belongs with its source.

What makes the film’s box-office run notable?
Iron Lung opened domestically on January 30, 2026. The Numbers lists a production budget of $3 million, a database-reported figure rather than independently audited production accounting. Compared with that reported budget, the film’s reported theatrical gross is substantial; gross receipts are not the same as profit, since the figures do not account for distribution costs, marketing, or the division of ticket revenue.
The YouTube Official Blog described Mark Fischbach, known as Markiplier, as self-funding, directing and starring in the film, then eventually self-distributing it to more than 3,000 screens. The blog also said fans lobbied theaters to show the film. That account provides release context, but does not establish the film’s net earnings.
What is Iron Lung about, and where can viewers find it?
The Numbers describes it as a live-action horror and science-fiction film based on a game, with isolation-horror elements. The database lists a 127-minute runtime and an R rating for language, bloody images and some gore. Box Office Mojo gives a runtime of 2 hours 5 minutes, a five-minute difference; the sources do not reconcile it.
The official film website currently labels Iron Lung “NOW ON DIGITAL.” It also lists film merchandise, including a commemorative T-shirt, poster, sticker, mouse pad and apparel. The site does not establish current DVD or Blu-ray availability.

Why did Markiplier make the film himself?
In a February 23, 2026 interview with the YouTube Official Blog, Mark Fischbach discussed the film’s connection to the game and details hidden in the background. He said: “No one has seen the secrets I’ve hidden in the background of that scene yet. I haven’t seen a single peep about them online.”
