Wall.E begins with an aerial shot of a city, seen through a smoky haze. But as the camera pans down we realise that some of the towers are not buildings, only vast repositories of rubbish. It is an abandoned city, devoid of life. Well, almost. Wall.E (Waste Allocation Load Lifter — Earth class) is the only one left in the city and he (because we now see that Wall.E might be a machine, but it has a soul) is lonely. In his home (festooned with fairy lights, with shelves of neatly sorted junk, and a TV) he endlessly watches a sequence from the classic musical Hello Dolly, in which people sing and dance and the sun pours down from a cloudless sky.
