Unfortunately there isn't a Macedonian version which shows a different picture of his sexuality. You don't have to camp with your enemy to learn about them. This is portrayed by the Greeks as common knowledge.
It is well-known that Alexander, like many in that culture, was bi-sexual. That said, I'll bet he also went to the bathroom as much as any man, both at home at between battles. Does that mean a movie should show him squatting in a field, searching for leaves in order to be "historically accurate"? Don't think so. Would that help ticket sales? Don't think so. Is Alexander's sex life an integral part of his story? Don't think so.
