The actors want more money, but they should be demanding better scripts instead. The show jumped the shark a long time ago. E! reports: Aye Caramba! The real-life alter-egos of Homer, Marge, Bart, Lisa and the rest of The Simpsons gang want more D'oh. Six of the show's voice actors have failed to turn up for two table reads in the last couple of weeks in a strong-arm bid for better pay, delaying production on the hit 'toon's 16th season, reports Variety. The suddenly silent include Dan Castellaneta (Homer, Krusty, Grandpa Simpson, Mayor Quimby), Nancy Cartwright (Bart, Nelson, Ralph Wiggum), Julie Kavner (Marge, Selma, Patty), Yeardley Smith (Lisa), Hank Azaria (Moe, Apu, Chief Wiggum), and Harry Shearer (Mr. Burns, Ned Flanders, Principal Skinner, et al). The work stoppage comes after reps for the Simpsons cast sought to renegotiate the terms of their current deal with Fox TV executives but met with little success.
