Practically the whole Pickford clan showed up in Fanchon the Cricket. Mary Pickford plays the granddaughter of a woman suspected of being a witch. The poor girl is rescued from the torments of her peers by the hero. She reciprocates by nursing him through an illness, and also by rescuing his feeble-minded brother from an unhappy fate. Pickford's siblings Jack and Lottie played supporting roles, but the main attraction was the film debut of teenaged dance team Fred and Adele Astaire--before they hit it big on Broadway. Frances Marion adapted Fanchon the Cricket from a novel by George Sand; curiously, considering the historical significance of the film, Marion had no memory of working on it when asked in the 1960s.
