Not all of them. Brian Grazer and Tate Taylor are American.
But they are furious nonetheless.
I wonder what the black posters here think about white people telling this black story? Or any black story? That blog site "Shadow and Act" gets upset whenever white people start to tell black stories. They would be enraged if Martin Scorsese did a film about Marvin Gaye or Jimi Hendrix or Steven Spielberg did a film about Jesse Owens or Jack Johnson.
As an Asian American, if white people started to tell our stories, I would be fine with it as long as they respect the Asian culture. I have no problems with Martin Scorsese directing Silence, because well...it's Martin Scorsese and the main protagonists are white anyways, even though the film is set in Japan. I didn't care much for 47 Ronin, because it didn't look good to begin with. I was fine with the Last Samurai being directed by a white director, because it was a really good movie.
