Documentary filmmaker and activist Michael Moore will be the next to make a special guest voice appearance on The Simpsons. An Oscar winner for “Bowling For Columbine,” Moore will appear on the episode, “The President Wore Pearls”, which airs at 8pm on Sunday. Moore had this to say about his appearance: “Ever since Bart’s class went to the box factory in Flint a number of years ago, I have hoped to make it on ‘The Simpsons’ one day. However they draw me is bound to be an improvement on the original thing.” Moore will star as himself, helping Lisa in a revolt at Springfield Elementary. We’ll tell you more about this episode in our reminder on the weekend.
