I complained about the casting of The Odyssey per se (the blind beggar was best), but in general I do not mind cross-ethnic casting. I am glad Elizabeth Taylor played Cleopatra, Dev Patel played David Copperfield, Denzel Washington played Macbeth, black and Latino actors play white parts in Hamilton, and that Morgan Freeman can play God well (God himself would not be “white,” but God as black is nonetheless a conscious choice), and there was Jessye Norman (among others) singing and playing many traditionally white roles on the opera stage.
Recently in a private conversation I suggested that Nabeel Qureshi be cast as the next James Bond. He has a British accent, was born in (northern!) England, is tall and is good-looking. He does not remind anyone of Roger Moore. He is old enough where you could believe he has some experience as a spy, and at the baccarat table, but young enough where he could do those stunts without it seeming ridiculous.
I recall the talk of a black Bond, a notion which likely would end up dull and cliched. But a Bond of Pakistani ethnic origin? Now that would occasion some debate.
I am not saying it always works. I likely would object to a remake of Zulu with an all-Chinese cast. Or there can be major cultural mistakes which are not cross-ethnic, such as casting a Liverpudlian in the role of a London elite. Everyone in The Sopranos should at least be pretending to fit their roles, and indeed Tony himself grew up in New Jersey. I would have done fine in a cameo role.
