Moviegoers are saying
Markiplier's ambitious indie horror debut 'Iron Lung' divides audiences with its claustrophobic submarine thriller that transforms a one-hour video game into a two-hour psychological endurance test. While some praise the YouTuber-turned-filmmaker's impressive cinematography and genuine scares, others find the pacing glacial and the ending frustratingly unclear - though most agree it's remarkably well-crafted for an independent production.

skrunklyJan 29, 2026I had no idea what the video game this is based on was about so it was fun trying to piece it together and it went on, which is kinda the point, but it became mostly incoherent by the end. Nonsensical but not in a good way, wasn't reaching for huge ideas, stuff just…

0.1 - My first draft of this review got deleted while I was typing & now I’m even more mad. This is unequivocally the worst theater movie I’ve ever seen, & one of my least favorite movie experiences of all time. And that’s saying a lot coming just 24 hours after I saw Mercy. The quick hits are:…
ellie lovedIron LungSimon better than me I would have ended it all the MINUTE the submarine submerged
ChungiBoi is "meh" onIron LungMarkiplier should really be commended for how much he’s able to do with limited resources and material to work with, however, the movie is incredibly dialogue based, and I didn’t think that it was engaging enough to keep me hooked for how long the film was
- Obihulk lovedIron Lung
When many think of the horror genre. They would think of the immense creativity that can come from the use of Practical effects,CGI or wonderous camera angle that many would deem impossible to achieve without impeccably unnatural bodily movements. Now I have been a markiplier fan for nearly a…
Taylor Winters likedIron LungI like Markiplier and thought he was great in this, especially in the end. The beginning starts slow and suffers a bit. The one location really constrains this movie as it’s mainly just Markiplier talking to voices on a radio. But when the second half hits there’s body horror, creepy voices, and…
Minou A lovedIron LungI loved it!🤩 Seeing everything get more and more bloody and Simon get more and more sick from radiation, it kept me on the edge of my seat. Ive seen complaints about it being slow, I think it was great and honestly kind of refreshing (movies now throw as much as possible at you😐)
- Nat likedIron Lung
I liked it a lot, this world is so interesting. It could’ve been a bit shorter & I’m definitely gonna need a rewatch with subtitles (overlapping voices or voices with scratchy sfx is a very cool stylistic choice - unfortunately makes it almost impossible to hear) but if anything-
Ultimo_Joe likedIron LungI think this is good. I find it confusing in parts but I think that’s the point. Like the game, we are counting on the character with little knowledge to learn more, and although not all questions are answered, we certainly learn a lot as it progresses. Well shot, well acted 7/10
vi saunders lovedIron Lungif you have a dopamine addiction you are not going to like this movie. he does not change setting once in the movie. I thought it was great. it really followed the game and I just like him as an actor as well. I love the angles so if you like cameramen and directors.

I appreciate a good, slow burn from time to time. Very unsettling but enjoyable to a surprising degree. I don't think I've been this entertained by a movie taking place in a single room since Nefarious a few years ago. Would recommend!
NJNikki JeskeIt was a waste of 2 hours. It was hard to hear the characters and understand them. The plot was unclear. It was an awful movie.

As someone who is not a gamer at all, doesn't follow YouTube guys, and didn't even know who Mark was - this is a solid movie! I'm a huge cinephile and love to support independent films. This was a wild ride! Very impressive for someone who doesn't come from a filming…
JIJoanne IkerdI am in shock. None of my questions were answered and I’m okay with it because that was awesome
RMRobert MunizagaGreat movie, uses suspense very well

independent film is the future
RYRowan YoungHis body really went "further beyond" xD Mark really made something special here. One of few films I'd want to own on DVD to rewatch
MMMary MorganMark has outdone himself in every way! Him and his awesome team that put this whole film together. Every scene, every line, was deeply thought out. Every bit of hard work over the past three years has come to this, and it was worth every second. So proud of Mark and how far…

Despite Fischbach’s arguably admirable intent and exertion, this low-budget sci-fi horror makes Event Horizon look like 2001: A Space Odyssey.

Many of us have long sensed culture is making a decisive break with the analogue in favour of the (perhaps terminally) online and Fischbach’s film makes that paradigm shift not just visible but visceral; it feels not unlike spending 12 hours on Twitch with all the curtains closed.

Iron Lung is audacious and at times astonishingly boring. Still, it feels more enthusiastic and celebratory than many blockbuster adaptations built on safer math.
