The most outstanding dialogue from 'Shakuntala Devi''s trailer that stays with you is, 'When I can be amazing, why should I be normal?' Nobody else other than Vidya Balan can utter these priceless words with confidence and nonchalance together in a breath.The fantastic trailer of Balan's upcoming film dropped earlier on Wednesday afternoon, and one can't help but succumb to the charming world of mathematics weaved by the legend of world renowned mathematician Shakuntala Devi, an untrained young girl who grows up to become famous and be hailed as a 'human computer' and eventually, a Guiness World Record holder.At the core of the film lies a story of achievement. But one that comes with a price. The story showcases how Devi attained professional success but at the cost of personal loss. An everywoman story, Balan is joined by Sanya Malhotra, who plays her daughter Anupama, Bengali actor Jisshu Sengupta, who plays her husband Paritosh Banerji and Amit Sadh, who plays Anupama's husband, Ajay.Directed by Anu Menon, 'Shakuntala Devi' premieres on Amazon Prime Video on July 31st, 2020.Watch the trailer below.
