Another 'Simpsons' movie not in the works

LOS ANGELES, March 10 (UPI) -- "Simpsons" creator Matt Groening says a followup to the TV show's 2007 blockbuster film won't be happening for a long time.

Groening's comments came Saturday night during the University of California Los Angeles' annual entertainment symposium, The Hollywood Reporter said.

"It took us four years [to make] and it killed us," Groening said of "The Simpsons Movie."

The movie "stole animators from the show," Groening said, adding that despite bringing in $500 million, it drained other resources.

Another "Simpsons" movie will come in "Maybe another 10, 15 years," added longtime "Simpsons" producer-director David Silverman.
