First image: the Earth as a garbage dump, a future reduced to ruins. For the past 700 years, what's left of humanity has been cruising the skies in a spaceship. Only a tiny robot,
WALL-E (for Waste Allocation Load Lifter: Earth class), scoots around on urban terra firma compacting trash into piles that grow into skyscrapers.
First sound: a voice lifted in song: "Out there/there's a world outside of Yonkers." The tune is "Put On Your Sunday Clothes," a merry ditty from the forgotten 1969 movie
