YouTuber Markiplier has stunned Hollywood with his self-funded horror film, Iron Lung, which has grossed $26.8 million worldwide on a budget under $3 million.
The film opened on January 30, 2026, in just 60 U.S. theaters before quickly expanding to more than 4,000 screens globally. Its domestic opening weekend earned $18.2 million, including $8.9 million on Friday alone, securing the #2 spot behind Disney’s Send Help.
Markiplier wrote, directed, produced, starred in, edited, and distributed the film entirely on his own. He funded the $3 million through his Markiplier Studios, turning down a role in Five Nights at Freddy’s to keep full creative control.
Iron Lung is an adaptation of David Szymanski’s 2022 indie horror game. It follows convict Simon, trapped in a submarine navigating a “blood ocean” on a moon after a cosmic catastrophe. The production used 80,000 gallons of fake blood, causing Markiplier to be briefly hospitalized for eye irritation.
The movie also features voice cameos from fellow YouTubers Jacksepticeye and Valkyrae, along with Troy Baker. Critics gave it mixed reviews, praising the claustrophobic tension but noting pacing issues. Rotten Tomatoes currently rates it at 54%.
Despite the critiques, the financial success is undeniable. The film has already paid substantial bonuses to the crew, with Markiplier taking home half the gross. Analysts say this marks a turning point for fan-driven projects, showing that YouTubers can compete with traditional studios.
Markiplier told The Wrap, “I thought it would come out in 200 theaters. You believed in me… I’m really, really happy, and I’m really grateful.” Tickets are still available through ironlung.com.
The film’s success has sparked debate about the future of Hollywood, with many saying Iron Lung proves that independent creators can rival big studios when backed by dedicated fanbases.
