Helmed by Anu Menon, the story revolves around Shakuntala's ability to make incredibly swift calculations on her fingertips. Popularly known as 'mental calculator', her unique talent was first discovered at the age of 5 when she solved a math problem for 18-year-old students.

The biographical film will also see other stars as Sanya Malhotra and Jisshu Sengupta in supporting roles.

Vidya had paid tributes to the genius on her 90th birth anniversary on November 4.
