I don't deny that a lot of the examples given are either of people behind relatable everyday products and brands, or world-shaping historical events that every laymen has some inkling of. Or that in Congressman Wilson's case, a colorful and flamboyant personality beyond the potential 9/11 connection.
Certainly when it comes to WWII era technocratic bureaucrat-administrator types I'd be more interested in, say, a film about the National Recovery Administration's first Director Hugh S. Johnson, who was a bit of a crank and flame-out and perhaps had extremist views of modern day political salience. (I don't think he had anything to do with the alleged Business Plot, but a movie can easily evoke it and hey, Smedley Butler appearance as a character.)
But yeah, a movie about an administrator who was simply competent and important in an abstract systems-based way without personal drama or controversy does seem somewhat difficult to turn into a full-fledged biopic. Maybe a PBS mini-series?
