Markiplier’s breakout horror feature “Iron Lung” is set for a digital premiere on YouTube on May 31. Multiple outlets report that Markiplier announced the date during a panel at the Cannes Film Festival. The film’s YouTube debut is described as a YouTube exclusive, with viewers able to purchase the movie on the platform rather than streaming it via free or subscription access. Sources also note that the release follows the movie’s theatrical run, which concluded ahead of the home viewing window. TechRadar characterizes the timing as roughly four months after the film’s theater release. Forbes highlights that there is a “catch,” referring to the purchase-only nature of the release on YouTube. Overall, the announced plan is consistent across coverage: “Iron Lung” reaches viewers digitally on May 31 via YouTube, where it is made available for purchase exclusively.
