This is Day 9 of FXX’s mega-marathon of The Simpsons – and it’s the day that includes, in the proper order in the series’ overall narrative sequence, the 2007 big-screen The Simpsons Movie. It’s televised at 6 p.m. ET, and it’s especially entertaining to watch in retrospect, since it involves the town of Springfield being cut off from the rest of the world by a mysteriously appearing giant see-through dome. Sound familiar, Under the Dome fans?
