Markiplier's directorial debut, Iron Lung, scored a very impressive opening weekend at the box office.
The sci-fi horror stars YouTuber Markiplier, real name Mark Fischbach, who also writes, directs, and stars. The story revolves around a convict (Markiplier's character) who, on a post-apocalyptic moon, must use a submarine – that he's welded inside of – to go on a mission through an ocean made of blood. It's based on the 2022 video game of the same name.
