Markiplier's horror film Iron Lung led the box office on Friday with an estimated $8.9 million from 3,015 theaters. The movie, released on January 30, 2026, beat back challengers from directors Sam Raimi and Jason Statham, along with other new releases. This strong start comes after $3.5 million in Thursday previews and $6 million in pre-sales.
Background
Iron Lung marks the directorial debut of Mark Fischbach, known online as Markiplier. He wrote the script, starred in the lead role, and financed the project through his company, Markiplier Studios. The film adapts a 2022 indie horror video game by David Szymanski. It follows a convict named Simon who pilots a small submarine called the Iron Lung through an ocean of blood on a desolate moon. This mission happens after an event called the Quiet Rapture wiped out all stars and habitable planets, leaving humanity in a post-apocalyptic world.
Production took place in Texas. The budget stayed under $3 million, with minimal spending on marketing. Fischbach handled much of the promotion himself via social media. During filming, the movie used over 80,000 US gallons of fake blood, more than any horror film before it. Fischbach ended up in the hospital after some got in his eyes.
The film earned an R rating for language, bloody images, and gore. It runs 127 minutes. It opened wide in North America on January 30, 2026, and also in parts of Europe, Australia, and New Zealand. Fans pushed for wider release by requesting showtimes at chains like AMC, Cinemark, and Regal. This effort expanded it from 60 independent theaters to over 4,161 screens worldwide.
Key Details
Iron Lung pulled in $3.5 million from Thursday previews, including early Tuesday and Wednesday screenings. That figure topped Sam Raimi's Send Help at $2.2 million and others like Black Phone 2 at $2.6 million. Pre-sales reached $6 million before the weekend. Friday's $8.9 million put it in first place. Opening weekend projections now sit between $10 million and $17 million domestically.
The cast includes Fischbach as Simon, with Troy Baker, Caroline Rose Kaplan, Elle LaMont, Seán McLoughlin, Alanah Pierce, and others. Isaac McKee plays a young Simon. David Szymanski, the game creator, makes an appearance.
Audience response has been strong. On Rotten Tomatoes, it holds a 90-93% audience score from over 100 verified reviews. Critics have mixed views so far, with early scores calling out pacing issues but praising ambition.
Competition Breakdown
Sam Raimi's Send Help landed in second place after previews. Jason Statham's new action film and other newcomers trailed. Mentions of Melania Trump tie to another release, but Iron Lung stayed ahead. Domestic box office so far lists it at $9 million total, with inflation-adjusted figures around $3.5 million.

What This Means
Iron Lung's success shows the pull of video game adaptations, especially with built-in fan bases. Low budgets and grassroots marketing can compete against big studio films. For Fischbach, this debut opens doors in Hollywood. It ranks among top openings for R-rated horrors and self-financed projects.
Theaters report high attendance from young adults and horror fans. International markets in Australia, New Zealand, and the UK saw similar buzz. Weekend totals will confirm if it holds the top spot through Sunday. Strong word of mouth could push earnings higher. Other films like Send Help may adjust strategies based on this performance.
Box office experts watch how frontloaded the run will be. Video game movies often peak early due to fans. Iron Lung's long runtime and isolation theme draw comparisons to underwater thrillers. Its place on all-time lists for domestic and worldwide R-rated releases highlights the surprise hit.
Production details like the massive blood use add to its gore appeal. Hospital incident during filming shows commitment to practical effects. Wide release expansion proves fan power in theater bookings. Early rankings put it in the top 7,400 domestic earners already, adjusted for inflation.
This opening sets a benchmark for YouTuber-led films. Future projects from similar creators may follow this model. Studios note the $3 million budget return in previews alone. Projections adjust upward as Saturday numbers roll in. The film's sci-fi horror mix resonates in a crowded market.
