Markiplier is bringing his horror film Iron Lung to digital audiences after its theatrical release, with the creator confirming that the film will be available to rent or purchase on YouTube from May 31.
Iron Lung to start streaming soon
The streaming rollout marks the next phase in the release strategy for the independently produced psychological horror project, which has become one of the most closely watched creator-led film ventures in recent years. Based on the cult indie horror game developed by David Szymanski, Iron Lung initially generated widespread attention due to Markiplier’s involvement as writer, director and lead actor.
The film’s digital release on YouTube reflects the creator’s longstanding connection with the platform where he built his global audience over the past decade.
The original game gained popularity for its stripped-down, claustrophobic approach to horror storytelling. Set inside a small submarine navigating an ocean of blood on a distant moon, the narrative relies heavily on atmosphere, isolation and psychological tension rather than conventional jump scares or action-driven sequences.
Markiplier’s adaptation expanded the concept into a feature-length film while attempting to preserve the unsettling tone that helped the original game develop a devoted following among horror fans and gaming communities.
The film’s theatrical release earlier this year drew particular attention because it represented a rare example of a major YouTube personality independently steering a cinematic project into traditional cinemas before moving into digital distribution.
Fans had spent months awaiting updates on the film’s wider accessibility following its theatrical rollout, with many international viewers unable to attend cinema screenings. The YouTube release is expected to significantly broaden the film’s reach among Markiplier’s global audience, many of whom first discovered the creator through horror gaming videos.
Iron Lung will become available to rent or purchase on YouTube beginning May 31.
