Fan Casting The Simpsons Movie (2009)

One summer on Lake Springfield, Green Day, after finishing a concert, tries to engage the audience in a discussion about the environment, angering the audience into throwing garbage at them, causing the pollution in the lake to erode and sink the band's barge, drowning them. During their memorial at Reverend Lovejoy's church, Grampa Simpson has a spiritual experience and frantically prophesies that a disaster will befall Springfield, but only Marge takes it seriously. Concerned about the terrible state of the environment, Lisa and her new love interest, Colin, hold a seminar where they successfully convince Mayor Quimby to tell the town to clean up the lake. Meanwhile, after a series of dares, including one with Bart skateboarding across Springfield naked and getting in trouble with Chief Wiggum, Homer and Bart go to Krusty Burger, where Homer adopts a pig that Krusty the Clown was about to have killed after filming a commercial there. Marge, identifying the pig as a part of Grampa's prophecy, warns Homer to get rid of it, but Homer refuses. Homer's fawning over the pig makes Bart, now fed up with his father's carelessness, look to their neighbor, Ned Flanders, as a father figure.
