The Simpsons cast has sealed a four-year deal that hands it more “D’oh” and solidifies the animated hit’s 20th season, says Variety. Production on the show has been delayed for several months as voice actors and 20th Century Fox TV hammered out a deal. New pact bumps the stars’ salaries up to about $400,000 an episode; the thesps previously made somewhere in the mid-$300,000 range. Although the voice actors are now locked through the next four years, it doesn’t necessarily mean The Simpsons will be back beyond season 20. Gracie Films’ deal with 20th expires at the end of this season, and Fox hasn’t renewed the show beyond this upcoming year. Because of the late start, 20th will produce just 20 episodes of The Simpsons this season instead of the usual 22.
