In addition to Dr. Hibbert, Shearer voices several other Springfield residents: Principal Skinner, Reverend Lovejoy, Ned Flanders, and Waylon Smithers.
Harry Shearer, who plays a myriad of characters on The Simpsons including the African American physician Dr. Hibbert, has spoken up about the matter in an interview on Times Radio.
Perhaps most specifically is the decision by several animated television programs to replace white voice actors playing people of color with voice actors of the correct ethnicity.
Shearer made it clear that he was not “opining” on whether or not the producers made a mistake.
