Just as "Modern Times," despite its mordant view of modern industry, became Chaplin's cheeriest film because of the Tramp's romance with a "gamine" (Paulette Goddard), "WALL-E" became one of Pixar's most piquant and satisfying films because of WALL-E's courtship of EVE, the svelte Extra-terrestrial Vegetation Evaluator sent from the Buy N Large mother ship to see if plants have started growing again on Earth. EVE helped Stanton locate the core of the movie and also simply added to the pantomimed fun: "I already had one 'person" who spoke a different language than I did, and now he'd fall in love with someone of a different nationality who spoke another language."If "Modern Times" inspires new Chaplin fans in your circle -- or makes you a Chaplin fan all over again -- check out Richard Attenborough's sprawling (also gimmicky and damnably respectable) biopic, "Chaplin," if only to see the astonishingly talented Robert Downey, Jr., in the title role. Downey embodies the distinctive Chaplin blend of spunk, poetry, and enigmatic sensuality. In the film's most diverting patches, Downey reaches the same combination of balletic grace and robust iconoclastic farce that Chaplin did in a half-dozen classic features and scores of inspired silent shorts.
