- Quick Answer: Markiplier's sci-fi horror sensation Iron Lung can now be watched via YouTube (or Google TV), where it is available to rent for $4.99 (£3.49) or purchase to own for $9.99 (£7.99).
Markiplier’s Iron Lung has become a surprise box office hit, grossing over $50 million worldwide from an estimated $4–5 million budget.
The film follows a convict navigating a blood-filled ocean on a distant moon in a submarine called the “Iron Lung,” searching for relics in a post-apocalyptic future.
Keith Stuart of The Guardian notes that the film “feels like watching Fischbach play Iron Lung the game,” with long sequences of puzzle-solving, close-ups of the protagonist thinking through challenges, and narrative elements that mimic the experience of a YouTube playthrough. This meta, game-like storytelling is part of why the film has resonated with fans, despite its unconventional style.
Want to check out the film? Here’s the latest on where to watch Iron Lung online, and how VPN services like ExpressVPN and VeePN can help if the film isn’t available in your region.
Where to Watch Iron Lung Online
Because Iron Lung was an entirely self-funded, independently distributed project, its road to home viewing has looked a little different than a traditional Hollywood blockbuster.
Rather than going to standard platforms like Netflix or Prime Video right away, Markiplier has stuck to his roots and released the film on YouTube (also available on Google TV), with Iron Lung costing $4.99 (£3.49) to rent, or $9.99 (£7.99) to buy.
- Note: Rentals typically give you a 30-day window to start watching, with 48 hours to finish the movie once you hit play.
How to Watch Iron Lung from Anywhere
Since YouTube relies heavily on regional licensing, availability might vary depending on where you reside. So, if Iron Lung isn't showing up in your local digital marketplace, a Virtual Private Network (VPN) can help bridge the gap.
By encrypting your internet traffic and routing it through a server located in a different country, a VPN makes it appear as though you are browsing from that territory, allowing you to safely bypass regional access blocks.

Is an Iron Lung Sequel on the Horizon?
So far, there are no official plans yet to do a sequel to Iron Lung, but its box office success might lead to the possibility of doing a follow-up.
In his YouTube live stream, Markiplier celebrated the surprise success of his film and how it showed that an independent project can still achieve this feat. He said:
- "I’m tearing up at the beginning of this. It’s been a bit of an emotional day in the best way possible. So I’ll first say, ‘Thank you guys so much."
- "I personally don’t care about the numbers, other than, ‘Woohoo, success.’ I’m going to be able to give the crew a big bonus. That’s awesome. I’m not a big studio. So the split with the theaters is basically 50-50. It’s really cool because everybody wins."
Markiplier added:
- "It’s kind of a hero moment to showcase indie filmmaking is possible."
