Harry Shearer has confirmed active work on the first Simpsons feature movie. Shearer broke the news during an appearance on the Mancow radio show, and a listener sent in a report to the AICN website: “Harry Shearer … mentioned the two year contract extension [for the TV series] and then was asked … if this [would] delay the movie project by two years. His response was that it would not delay it, because they were recording dialogue for it right now.” Shearer stated that the language of the movie is going a little more edgy than what is run on TV, but not enough to receive a “restricted” rating.
Shearer’s comments show just how quickly progress is being made on the Simpsons movie. When IGN reported on it last September, not even a script had been completed yet.
