But if they SO BADLY want a "white savoir", then Danny Glover can do a "twist" like MOST historical films do. Like say there were some whites helping the revolution and one of the main characters were white. I mean thats if Glover desperately wants the movie to get green lighted.
Also he can be historically accurate with the "white savoir", because the Polish betrayed the French and helped the rebels(which is why Polish people are granted free citizenship to Haiti till this day), but iirc that is way after Toussaint.
He could probably fit all of that in the movie if it's more about the Haitian Revolution and not just follow Toussaint L'Overture but have POVs of all the key players on the Haitian side.
