We come here to speculate and shoot the bull. Many things in history can't be proven and if we could only talk about those things that can be proven we'd have little to talk about.
On one hand, and perhaps superficially, one would think Washington's bio would be a logical subject for Hollywood. After all, most countries do not have a Founding Father, so tangible, so close. He's not the sons of Noah. On the other hand, it is my speculation that this avenue has not been traveled because his status is too iconic.
Reactionaries take offense at this and complain about "PC", as though being politically correct is a bad thing.
I, for one, never complain about political correctness. Because if I am "complaining," it can't be correct. lol
