A feature film on the life and times of ‘Rosogolla’ inventor in Bengal, Nobin Chandra Das, in 19th century Kolkata as the backdrop, is set to hit the screens by this year-end. The Bengali film ‘Rosogolla’ seeks to capture the journey of Das, from a humble background to a business tycoon. Das had invented Rosogolla by dipping cotton cheese ball in sugary syrup (in 1868) after trying various combinations. The film is being directed by Pavel and produced by Shiboprosad Mukhopadhyay and Nandita Roy, directors of a string of blockbusters. “Being a feature film, it is not a biopic. It is partly based on real-life events and there are some fictional accounts,” the director told a news agency.
