I agree completely; I just couldn't think of a semi-recent film where a historical person was whitewashed. It's especially relevant because as a political leader of a conquering dynasty, Cleopatra's differing heritage from her subjects may have, probably did have, effects on how her people thought of her and how she was able to wield power. The way the Ptolemy dynasty interacted with the people of Egypt is something I know almost nothing about and would have been very interested in seeing depicted onscreen.
