Mark Fischbach's Iron Lung Film Debut Offers Claustrophobic Sci-Fi Horror Experience

Iron Lung is a claustrophobic sci-fi horror film marking YouTuber Mark Fischbach's feature debut as writer, director, and lead actor. Based on David Szymanski's indie game, it follows Simon, a convict piloting a submarine through a blood ocean on a distant moon after a cosmic disaster. Reviews highlight its strong atmospheric dread and effective tension in confined spaces, though some critique its pacing and repetitive moments, noting it may appeal more to fans familiar with the game and Fischbach's style.
