Magicians show you things you don’t know you’re seeing. Prosecutors tell you things you don’t realize you’re hearing.
Movies use a similar ploy: they make you feel smart and perceptive about details they want you to regard as facts.
In other words, they hide clues in plain sight. (Like the Purloined Letter)
This can make moviegoers feel superhuman; like they can see into the future and under the surface of things.
A great movie will exploit this feeling to hide a greater truth under an obvious fiction.
The moment in Black Panther (2018), when the ship flies into the dusty ground of an impoverished nation and emerges under blue skies, above a hidden kingdom of peace and wealth: that was some deep, deep shit.
