[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.]
From 2011 Kevin.
