Based on the story by Paul Gallico, Lili stars Leslie Caron as the title character, a 16-year-old waif who runs off to join a carnival. Embittered, crippled puppeteer Mel Ferrer treats Lili with contempt; only by speaking through his puppets is Ferrer able to express his genuine love for the girl.
Before this happens, however, Caron must overcome her crush on magician Jean-Pierre Aumont, who is married to the contentious Zsa Zsa Gabor.
Though not a musical (as was Carnival, the 1961 Broadway version of Lili), the film affords Leslie Caron the opportunity for a dream ballet, and also accommodates the lilting Bronislaw Kaper/Adolph Deutsch hit song Hi Lili, Hi Lo.
Legend has it that professional curmudgeon H.L. Mencken, who considered movies a waste of time and never bothered to see them, was persuaded to attend a showing of Lili--and loved every minute of it!
