Iron Lung is an upcoming American science fiction horror film written, directed, executive produced, edited by, and starring Mark Fischbach in his feature directorial debut. Produced and distributed by Markiplier Studios, it is an adaptation of the 2022 video game of the same name by David Szymanski, and also stars Caroline Rose Kaplan, Seán McLoughlin, Szymanski, Troy Baker, Elsie Lovelock, and Isaac McKee in supporting roles.
Development on a Iron Lung film adaptation began in April 2023, when YouTuber Mark Fischbach, known online as Markiplier, announced he would be adapting the game into a horror film. Fischbach, who had previously played Iron Lung on his channel, announced the film would be self-financed, star himself alongside co-star Caroline Rose Kaplan, and use his own script. Szymanski has also confirmed that he has been involved with the film since pre-production, assisting with its screenplay and being on set during filming, and that he is set to have a small cameo in the film. It is set to be the first theatrical film directed and produced by Fischbach, who co-produced it alongside Will Hyde and Jeff Guerrero.
Iron Lung is scheduled to be released on January 30, 2026.
The film is set in a post-apocalyptic future after an event known as "The Quiet Rapture" caused all known stars and habitable planets in the universe to disappear. A convict (Mark Fischbach) is sent to explore an ocean of blood discovered on a desolate moon using a poorly constructed midget submarine nicknamed the "Iron Lung". [2]
On February 16, 2023, David Szymanski jokingly announced on Twitter that Mark Fischbach and Seán McLoughlin (known by their online usernames Markiplier and Jacksepticeye, respectively) would be starring in a film adaptation of the game Iron Lung which Fischbach and McLoughlin both played, with a soundtrack by Andrew Hulshult, slated for a summer release. [7] [8] In an interview with Variety on March 8, 2023, Fischbach confirmed he was directing, writing, and acting for a film, but did not state what it was. [3] On May 7, 2023, McLoughlin confirmed on Twitter that he would be in the film. [9] Szymanski has assisted with the script and pre-production of the film, and is also set to have a cameo in the film. [8] Andrew Hulshult was also confirmed to be scoring the film. [10] Iron Lung is the first film soundtrack that Hulshult worked on. [11]
On April 21, 2023, Fischbach officially announced a film adaptation of Iron Lung with the release of a teaser trailer. [2] [12] [13] Additionally, Deadline Hollywood reported that Fischbach was also self-financing the film, co-starring with Caroline Rose Kaplan, and producing with Will Hyde and Jeff Guerrero; filming had already commenced in Austin, Texas. [14] Szymanski confirmed the film is intended for a theatrical release, [15] marking the film as Fischbach's first theatrical film; he previously directed and wrote the YouTube Original interactive films A Heist with Markiplier (2019) and In Space with Markiplier (2022). [14]
During production, Fischbach confirmed that Iron Lung will contain the most fake blood of any horror film, beating 2013 film Evil Dead 's 50,000 US gallons (190,000 L); [16] [17] during filming, he went to the hospital due to getting too much fake blood in his eyes. [18] In a YouTube livestream posted on December 7, 2025 he revealed that the approximate amount of blood for the final movie was over 80,000 US gallons (300,000 L). [19]
On April 29, 2023, Fischbach announced on his YouTube channel that filming had been completed, marking the beginning of the editing and post-production process. [20] In July 2023, Fischbach revealed that he is a member of SAG-AFTRA, and that the production of Iron Lung would be delayed due to the 2023 SAG-AFTRA strike. [21] [22] On October 14, 2023, Fischbach published the official trailer of the movie on his YouTube channel. [23] [24] On October 16, in a livestream on his YouTube channel, he stated that he had turned down a role in Five Nights at Freddy's in order to produce Iron Lung, due to the two films having conflicting production schedules. [25]
In June 2024, Fischbach announced that the film was "officially done", and that he was in the process of negotiating the film's release. [26] Initially set for a limited release, Iron Lung is scheduled to be released in the United States and Canada on January 30, 2026 in over 2,000 theatres. [27]
