Iron Lung creator gives glowing first impression of Markiplier’s movie adaptation

David Syzmanski, creator of the hit indie horror game Iron Lung, gave his first impressions of Markiplier’s long-awaited movie adaptation — and his takeaway should make fans excited.

YouTube star Mark ‘Markiplier‘ Fischbach first announced his ambitious plan to bring Iron Lung to the big screen in early 2023 with a cinematic trailer that mimicked the dark ambience of its namesake.

It’s been over two years since the project was revealed, with the YouTuber giving sporadic updates on the film here and there, saying it was “officially done” in summer 2024.

Things have been comparatively quiet in the year after, with Markiplier saying he’s bent on giving the flick a theatrical release. He’s been working closely alongside Iron Lung’s creator, indie game developer David Syzmanski, who’s gotten a first look at the full film.

Iron Lung creator praises Markiplier’s movie as “very good”

Syzmanski opened up about his impression of the movie in an episode of the Quad Damage Podcast on September 2, 2025 — and it’s safe to say that he’s thoroughly impressed by Mark’s interpretation of his vision.

“It is very good,” Syzmanski said. “I know I am the least unbiased source you could hear from, but the movie is very good. I don’t think people are ready for it.

“It’s a proper ‘movie’ movie. It’s not just, ‘Here, let’s make a fun little movie from the game.’ It’s a serious, proper horror film.”

He reiterated that Markiplier is focused on bringing the flick to theaters, revealing that the project was created “from the ground up” with a theatrical release in mind.

“That’s the hope,” he said when asked about the topic. “That’s why it’s not out yet. The plan has always been for it to release in theaters. It was filmed and scored and everything as a theatrical release. The sound for the movie was created and mixed for a theater, and it makes full use of that.”

Markiplier has admitted that the one thing holding back Iron Lung’s release is his refusal to compromise putting the flick in theaters. Once that happens, fans can finally expect to see it on the silver screen.

“I’m not accepting anything less than theatrical,” he said during an October 18 live stream. “That movie needs to be in theaters. There have been opportunities besides that, but I have not taken them…That’s what I want. That’s what I aim for, and that’s what I think it deserves.”
