Frigging Pieface got racebent. He has to be called Pie or Pieface for decades, but make a movie... cast a brown guy, doesn't matter what kind. And, not one single argument from any of these folks that raaaage over a black guy cast in a traditionally white role. Black guy in Asgard, they all lose their cool, but all-white Egyptian gods? Well, of course. All-anglo Hebrew fairytales? Of course, of course. Black Tulip O'Hare? "I don't see why she has to be..." Johnny Storm "has to be white." The Ancient One "has to be white to protect from racism." Iron Fist "has to be white" because nobody else can ever be an outsider or have racial tension with another race. White supremacy groups actually called for protests over the Bullet to the Head adaptation because they fired a problematic white actor and hired an Asian they already wanted to work with as his replacement. But, white people, white people can play anything.
If they cast three black actors in the major roles, from three different countries, does anyone think we'd still be hearing "It's to Americanize it. It's how it has to be"? Twenty-First Century, and "Americanize" still means using white European nationals, white Americans, white anybody, and never Asian Americans. Asian Americans are just too dang Asian to be in a movie about Asians.
