📍Austin, Texas, USA
Austin, Texas served as the main filming location for Iron Lung. The production team built the entire interior of the Iron Lung submarine inside studio spaces. These sets were designed to feel tight, rusted, and uncomfortable, helping viewers feel the same fear and isolation as the main character. Almost the whole movie takes place inside this submarine, making the Austin-built sets the heart of the film.
Specially constructed submarine sets were used to film nearly every scene. These sets included narrow hallways, metal walls, pipes, and mechanical controls. Real lighting, water effects, and moving parts were used instead of heavy green screens. This practical approach made the world feel real and added to the film’s tension.
Some parts of the production process took place in private locations in California. While no story scenes were filmed there, these spaces were used for technical work. Mark Fischbach converted parts of his own home into temporary production areas to help with visual effects and rendering. This shows how hands-on and independent the project truly was.
