Markiplier's Indie Horror Debut: What This Means for YouTube's Film Ambitions Markiplier's Iron Lung, initially a passion project, has achieved significant success despite its relatively low budget.
When it hits YouTube on May 31, the film will not only provide horror fans with another reason to tune in but also set a precedent for YouTubers turned filmmakers.
The $51 million worldwide box office haul is impressive, especially considering Markiplier's self funding and the film's modest budget.
