D'oh! Reuters reports that The Simpsons cast -- the actors, not the cartoon characters -- have stopped work in an attempt to force settlement of lengthy contract-renewal talks. According to insiders, Dan Castellaneta, Hank Azaria, Harry Shearer, Yeardley Smith, Julie Kavner and Nancy Cartwright each is holding out for about $360,000 per episode, or about $8 million per season.
