I'd love to see a filmmaker also sign off on the engineering plans to a bridge since everyone is so enthralled by, essentially, an art major's opinion on a scientific, geopolitical, and sociological endeavour.
A bridge engineering analogy might be a documentary about how we are incapable of funding infrastructure or how we struggle to design and build new kinds of bridges where they can’t currently exist.
Applied means real world. A script and movie set is not the real world. There is zero push back and change from unexpected real world vectors to test ideas on paper and on stage.
