Markiplier’s long-awaited horror movie Iron Lung finally has a confirmed theatrical release date: January 30, 2026. After years of delays, the film is now ready to hit theaters. Markiplier — whose real name is Mark Fischbach — wrote, directed, produced, edited, and stars in this movie based on the 2022 indie horror game by David Szymanski.
Tickets go on sale December 5, 2025, and the movie will premiere at the Alamo Drafthouse Cinema Downtown in Los Angeles on the same day.
Release Plan and Distribution
Iron Lung will open in 50–100 independent theaters during its first weekend, from January 30 to February 1, 2026. Instead of working with major studios, Markiplier is self-distributing the movie. This is a bold and rare move because he is partnering directly with theaters across the U.S.
There are no streaming or VOD details yet, as the team wants fans to watch it in theaters first. The movie went through a long three-year post-production process, with distribution issues causing major delays.
Fans can buy tickets on the official website ironlung.com. A final trailer has already been released and is getting a lot of attention online. Although the film finished shooting in June 2024, the long wait has only created more mystery and hype. This project is being watched closely as a major example of a creator-funded movie trying to break into the theatrical space.
Plot: A Terrifying Sci-Fi Horror Story
Iron Lung takes place after a cosmic disaster called “The Quiet Rapture,” which made stars and planets disappear. Humanity now survives on scattered space stations that are slowly failing.
A strange discovery on moon AT-5 reveals a gigantic ocean of blood. Scientists send a convict on a dangerous mission inside an old, rusty submarine known as the Iron Lung. The convict is locked inside with the viewport sealed shut because the pressure would crush it instantly. Their only chance at freedom is to complete the mission — if they fail, another person becomes “the next voyager.”
The whole story happens inside this small submarine, creating strong claustrophobic tension. Markiplier has teased that the movie may have the “world record for the most blood in a horror movie,” thanks to heavy practical effects. Fans can expect a dark, intense journey into the unknown, much like the game’s terrifying blind-navigation style.
Cast and Markiplier’s Many Roles
Mark Fischbach stars as the convict inside the Iron Lung. The cast also includes Caroline Rose Kaplan, Troy Baker, Elsie Lovelock, and a cameo by David Szymanski, the creator of the original game. Troy Baker, a well-known video game voice actor, brings extra attention to the film.
Filming began in Austin, Texas, in 2023. Markiplier handled almost every major creative job, despite many people warning him that it was too much for one person. He even joked that he turned his bathroom into a “render farm” because of all the editing equipment he had to install at home.
Iron Lung marks a big step in Markiplier’s career beyond his YouTube hits like In Space With Markiplier and Amazon’s The Edge of Sleep. With over 37 million YouTube subscribers and more than 73 million followers across platforms, his fanbase is helping drive huge online buzz.
Production Challenges and Delays
The movie was first announced in April 2023 with a short teaser. But after filming, it faced long months of editing, effects work, and the difficult challenge of finding the right distribution partners. Markiplier has called Iron Lung his “most difficult project ever.”
A teaser trailer in 2024 increased excitement, but fans had to wait through 2025 as the team finished the final details. Because Markiplier financed the project himself, he had full creative control — but it also meant he had to solve every problem on his own. Now, with the release set for 2026, Iron Lung stands alongside other popular sci-fi horror works, especially those set in deep or underwater environments.
Fans on Reddit, Instagram, and X (Twitter) continue to share excitement about the movie’s limited theatrical run.
Fan Excitement and Cultural Impact
Horror fans are thrilled to see Markiplier move from playing horror games to directing a full feature film. Many are watching to see if Iron Lung can become a box-office success in independent theaters. The trailer’s creepy shots of the blood ocean and tense monologue have helped build strong anticipation.
As 2025 comes to an end, Iron Lung represents a major moment in the creator economy. It shows how online creators can fund, produce, and release their own films — challenging the usual Hollywood system.
