YouTuber Markiplier is making a movie based on the cult game Iron Lung.

Markiplier wrote the script himself, takes the director’s chair and will play the leading role, Deadline reports. The film is shot in Austin, Texas and the YouTuber is funding the project himself.

Developer David Szymanski released Iron Lung last year. In this short game, players find themselves in a submarine in the distant future. The universe is nearly extinct and players explore the ‘blood ocean’ of a desolate moon.

Szymanski himself is also involved in the production and is therefore very enthusiastic on social media. He says that there are plans for a cinema release. The soundtrack of the film is also made by Andrew Hulshult, the composer of Doom Eternal and Dusk. The latter game is also from Szymanski.
