That it took The Simpsons a little extra time to catch on and impose a change is no surprise.
Apu, an Indian character in "The Simpsons", has been the source of controversy for years over its racial stereotyping. The documentary explored how people of South Asian descent felt about growing up with Apu as one of their only representatives on American television.

The debate over white actor Hank Azaria being the voice of Simpsons' character Apu, who is Indian, lasted for two years following Hari Kondabolu's documentary The Problem With Apu before Azaria announced in January that he would, after 30 years, no longer be playing the role.

Soon after, a joint statement from Josh Gad and Kristen Bell, the co-creator and star of Apple TV+ animated comedy Central Park revealed that white actor Bell would no longer be voicing the biracial character of Molly on the show.
There are big changes to the production of popular animated series The Simpsons, and they might have predicted this happening too.
