There was a big scare in Springfield a couple of months ago, when it looked as though Harry Shearer, who voices many of The Simpsons’ secondary denizens, including Mr. Burns, Waylon Smithers, and Ned Flanders, would be departing. But fear not! Fox has announced that Shearer, along with the show’s five other principal voice actors — Dan Castellaneta, Julie Kavner, Nancy Cartwright, Yeardley Smith, and Hank Azaria — will be returning for two more seasons. The two-season pickup extends the show’s phenomenal run to 28 seasons (it’s already the longest-running scripted show on TV). All’s well in Springfield: Homer and Marge aren’t breaking up, and neither are Mr. Burns and Smithers.
