Although copious evidence exists to confirm the homosexuality of Puyi, final ruler of the Qing, the creative heterosexual love scenes in the acclaimed film The Last Emperor have created a lasting impression in both Asia and the West that Puyi zestfully took advantage of his female concubines.
What? Hollywood rewrote history to conform to popular tastes?
You know, I bet so many “real” figures have been straight-washed for their filmic treatments that if every biopic for the next ten years included a prominent gay affair (at the very least) the result would be more true to life than the last hundred years of gay-free moving pictures. (I should note that Hollywood will make the occasional exception from its landscape of hets for the villain whose sexuality is merely more proof of his depravity.)
