Iron Lung’s visuals and lighting design are honestly better than most hollywood productions lately. The entire movie has this warm sepia color, and in different scenes, like the hangar, different colors appear just as vibrant. It’s well-lit! It’s not dark as fuck for no reason! It’s only dark in parts you’re not supposed to be able to see because Simon also can’t see.
It’s such a beautiful-looking movie and you can see how much love and care the team put into making it like that. I love it very much.
On that note, the sound design is also incredible when the theatre doesn’t fuck it up. It was always meant to sound extremely clear as well. Like the dark, it only sounded confusing and unclear when you were supposed to be confused - such as a speaker out of range, or the whispers.
