The Simpsons' Dr Hibbert: Harry Shearer replaced by black actor Kevin Michael Richardson

After more than 30 years in the role, Shearer's replacement reflects show's commitment to no longer have white actors voicing black characters

After more than 30 years playing Dr Julius Hibbert on The Simpsons, Harry Shearer will be replaced by voice actor Kevin Michael Richardson - seven months after the show's producers committed to no longer have white actors voicing black characters.

On Monday, Fox confirmed the episode that aired last night in the United States, Dairy Queen, would be Shearer's last as Hibbert. From Sunday, the doctor will be played by Richardson instead. Shearer will continue voicing his other characters, which include Mr Burns, Smithers, Principal Skinner, Ned Flanders and Reverend Lovejoy.
