Some American Black Pilots flew for Ethiopia when Mussolini invaded. They were the first to fight fascists, flying old ships, some from WW I, against the best the Italians had. I always thought that story would make a great movie.
The part about Italy invading to end slavery in Ethiopia and ending it being one of the very first acts of the Italian occupation freeing 100s of thousands of black slaves, and that Nazi Germany was aiding and supporting Ethiopia against Italy, complicates the movie.
I would not look pretty on screen without a heck of a lot of reworking of history.
