Iron Lung, the low-budget horror film written and directed by YouTuber Markiplier based on the video game of the same name, launched big at the global box office this weekend.
It earned $21.5 million globally, with an impressive $17.8 million coming from domestic theaters and $3.6 million internationally, having launched in just seven territories.
Markiplier, real name Mark Fischbach, distributed Iron Lung himself having spent a reported $3 million on production. That ensures Iron Lung is already a hugely profitable venture after opening weekend.
