Hollywood has recently embarked on the journey to undo whitewashing in the industry by recasting a number of POC roles that were voiced by white actors.
White actor Harry Shearer is stepping back from voicing the black Dr. Hibbert on "The Simpsons" after more than 30 years.
While some fans are mourning his departure, the latest white actor to think better of playing non-white parts, others are shocked and surprised that Springfield's favourite medical professional was as white as his lab coat.
We look at how Hollywood is realising that black voices matter:
Dr. Hibbert is only one of several characters of colour on "The Simpsons" to have been voiced for decades by white actors including his wife Bernice, Homer's nuclear plant colleague Carlton Carlson and of course, Apu, the Indian-American convenience store owner.
Hank Azaria's heavily-accented caricature of the grocer came under sharp scrutiny after comedian Hari Kondabolu's documentary "The Problem with Apu" fingered the performance as offensive.
Azaria finally quit the role last year, saying that continuing to play him "just didn't feel right."
Dr. Hibbert is now being played by Kevin Michael Richardson, while Carlson has been recast with another black actor Alex Desert.
'Aladdin' to 'Pocahontas'
Disney's "Aladdin" is one of the industry's most notorious examples of whitewashing, with white actors voicing the title role, Princesse Jasmine, and the Genie in the 1992 film.
At the time, the casting passed more or less unnoticed.
But Disney caused much more controversy when its live action film version in 2018 saw extras "browned up" with makeup to appear more Arab.
The studio's 1995 animated feature "Pocahontas" seemed to signal a bigger shift in thinking, however, with indigenous actors in all major roles, though Pocahontas's singing voice was lent by Judy Kuhn.
Disney has since put disclaimers on some of its classic films like "The Jungle Book", "Dumbo", and "Lady and the Tramp", warning that they include "negative depictions and/or mistreatment of people or cultures."
And this week "The Muppet Show" added a similar warning to 18 of its episodes.
'Bojack Horseman' and 'Big Mouth'
When Netflix's adult animated series "Bojack Horseman" ended early last year, actress Alison Brie apologised for voicing the main female character, Vietnamese-American Diane Nguyen.
The star – who also voiced Unikitty in "The Lego Movie" and played Trudy Campbell on "Mad Men" – posted a statement on Instagram in June saying "I now understand that people of color should always voice people of color."
Netflix's "Big Mouth" turned to its own writers' room to recast the voice of the chatty character "Missy". Black screenwriter and actress Ayo Edebiri is replacing Jenny Slate, of "The Secret Life of Pets" fame.
Slate said that she "reasoned with myself that it was permissible for me to play Missy because her mom is Jewish and White – as am I.
"But Missy is also Black, and Black characters on an animated show should be played by Black people."
White Denzel Washingtons
Outside the English-speaking world it is common for white actors to voice black, Asian and Latino characters in Hollywood movies.
In France, for example, the versatile Emmanuel Jacomy is voice of both Denzel Washington, Forest Whitaker and Pierce Brosnan, while the equally white Benoit Allemane has lent his dulcet tones to Morgan Freeman.
But more and more characters are being dubbed by black actors, with Will Smith, Idris Elba, Samuel L. Jackson and Eddie Murphy all now done by black or mixed race actors.
