Well, yes, it is a good point, isn’t it?
The only reason I mention it is that, in this day and age, I somehow find it hard to imagine a white actor being hired to play a black historical figure. While Mr Gatwa gets to play Marlowe, the writer of Tamburlaine and Doctor Faustus, I somehow doubt that, say, Keira Knightley would be cast to play the Nobel Prize-winning African-American novelist Toni Morrison, or that Hugh Grant would get the nod to portray the great Nigerian author Chinua Achebe. I tend to suspect that such casting would be considered not just inauthentic, but disrespectful. If not downright racist.
Nowadays, in fact, casting white actors to play black characters is unacceptable even in cartoons. This may seem curious, given that a cartoon’s audience is unable to see what race the actors are. None the less, we know it’s true, because in the wake of the Black Lives Matter protests of 2020, the Fox TV network announced: “The Simpsons will no longer have white actors voice non-white characters.” As a result, Harry Shearer, who is white, no longer voices the character of Dr Hibbert, who is black.
The same happened on another popular US cartoon, Family Guy. For 20 years, the character of Cleveland Brown, who is black, had been voiced by Mike Henry, who is white. But after the Black Lives Matter protests, Mr Henry announced that he was quitting the role, saying: “Persons of colour should play characters of colour.”
In summary, then, here are the new rules. A black actor may play a real-life historical figure who was white. But a white actor may not even provide the voice for a completely fictional character who is black. Please update your records accordingly.
We might even describe it as racist double standards.
