"Get ready to be enamoured by her wit, charm & of course, genius! Watch the video to know when #ShakuntalaDevi is coming to theatres near you!@sanyamalhotra_ @senguptajisshu @theamitsadh @directormenon @sonypicsprodns @abundantiaent @ivikramix @sonypicturesin," she wrote.
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.
