YouTube star Mark Fischbach, known online as Markiplier, said he was “tearing up” as he addressed fans during a livestream following the theatrical release of “Iron Lung” in late January. The Korean American creator self-financed the film and chose to distribute it independently, expanding the release from a planned 50-theater rollout to over 3,000 theaters nationwide after exhibitors reported strong demand. The film
opened to about $18 million domestically, representing well over half of its total gross, and went on to earn roughly $30 million in inflation-adjusted domestic ticket sales despite an average run of about two weeks per theater.
