The rickety wooden door, fraying at the edges, is painted a pale yellow, the very colour of faded memory. Above it hangs an unassuming, unpolished wooden nameplate, almost like a forgotten souvenir, barely visible in the dim light of the narrow corridor of a crumbling Calcutta mansion. Peer closely and you make out the legend inscribed on it: Calcutta Film Society. The very same CFS, indeed, the famed film fraternity, which Satyajit Ray and his close friend and renowned film critic Chidananda Dasgupta founded with others on October 5, 1947.
