The horror film adaptation of the indie game Iron Lung has achieved a strong box office debut, grossing $21.5 million in its opening weekend on a $3 million budget. Starring, written, and directed by YouTuber Markiplier, the movie highlights the potential for transmedia success from smaller games. It ranked second in U.S. charts, trailing only Sam Raimi's Send Help.
The film Iron Lung, inspired by David Szymanski's 2022 indie horror game, opened to impressive numbers despite its modest production. Released on a selective global scale, it earned $17.8 million from U.S. screenings alone, securing the second position on domestic box office charts behind Sam Raimi's horror film Send Help.
Mark Fischbach, better known as Markiplier to his 38.2 million YouTube subscribers, played a pivotal role in the project's success. Having popularized the original game among his audience, Fischbach took on writing, directing, and starring duties. Production began in 2023, with filming wrapping up in 2024. The narrative mirrors the game's premise: a pilot navigates a decaying submarine through a blood ocean on a distant moon in a post-humanity world.
The source game, launched on Steam in 2022, sold around 310,000 copies and later expanded to Nintendo Switch and PlayStation 5 platforms. This adaptation's performance, while strong for an indie effort, pales in comparison to bigger titles like Five Nights at Freddy's, which opened to $80 million but benefited from a larger existing fanbase and higher costs.
The success points to growing opportunities for video game movies, particularly from niche titles. Other indie adaptations in development include Dredge and Poppy Playtime. On the latter, Mob Entertainment's George Krstic praised their partnership with Legendary, noting the studio's 'deep understanding and care for the intellectual property.'
