Bengali actor Sayantika Banerjee recently joined Trinamool Congress (ANI) KOLKATA: The BJP's ambition to form its first government in West Bengal and the TMC's bid to seek a third term in power in the state has politically polarised the Bengali film industry and turned it into the parties' new battleground. The TMC's influence over the Tollygunge-based film industry, known by its portmanteau Tollywood, since even before Mamata Banerjee's ascendance to power in 2011, seems to have been waning with several celebrities shifting their allegiance to the saffron party. Ironically, the BJP, which seeks to unseat the TMC from power, has taken a leaf out of Banerjee's strategy of soliciting the tinsel town's support towards causes and fielding actors in elections.
