Mira Nair, the director of Salaam Bombay! and Mississippi Masala, brings us this cheery glimpse of the genesis, philosophy, and infectious popularity of the Bombay-based Laughing Clubs, founded by Dr. Maidan Kataria. Early each morning, mostly middle-class folks meet for their regular exercise regimen, a series of laughs, guffaws, and chortles. This technique, premised on the idea that laughter is the best medicine, has caught on throughout India, as a sort of taibo with giggles. If this captivating film doesn't raise a smile on your face, you should see a doctor. Produced by Adam Bartos. (30 mins, In Marathi with English subtitles, Color, 16mm, From Mirabai Films)
