Sen’s work is distinctly different in periods and thus draws in a plethora of cinephiles with discrete tastes. Ranging over a period of three decades, the 60’s, the 70’s and the 80’s, Sen’s cinema is constantly engaged in the dialogue between the past and present, thereby being dynamic enough to stay relevant. In Sen’s own words, his films were born out of his ‘passion’ and ‘dislike’ for cinema, which grew together at a certain time. Sen was an auteur, an experimenter whose aesthetics evolved through his journey. The younger Sen looked through the eye of the middle class man, who vehemently tries to move out of poverty, as in Akas Kusum (1965), the officer enclosed within the materialistic desires is shown the exploration of self in little joys by a tribal girl in Bhuvan Shome (1969) and in another case, a struggle to find a suit to wear to an interview, Interview (1971). With each work, Sen’s voice started becoming louder, apparent and after a point, he started shouting, to be heard above the noise of bombs and bullets during the Naxalite era of 70’s. It’s echoed in his Calcutta trilogy, Calcutta 71 (1972), Padatik (1973) and Chorus (1974). The choice of aesthetics became handheld shaky camera movements, jump cuts, breaking the forth-wall by making the character talk to the audience through camera. These aesthetic choices though is fuelled by the shoe-string budgets and the work of master cinematographer in Indian cinema, K. K. Mahajan, whom Sen discovered at the convocation ceremony of FTII, Pune. At another convocation at the film institute, Sen saw a stupendous unrelenting boy with no flair of shame. He is Mithun Chakraborty and Sen cast him for his film, Mrigaya (1976), the cult-classic on the uprising of the tribals against their oppressors. Sen adapted Munsi Premchand’s last story Kafaan, originally set in a U.P. village, setting it in Telengana. Oka Oori Katha (The Marginal Ones, 1977) tells the universal tale of exploitation in a small village thus avoiding the hurdles of shifting the story out of the hindi heartland.
