Vidya Balan is gearing up for the shoot of 'Shakuntala Devi', the biopic on the great mathematical genius. It will be shot in London. The makers today unveiled the film's short teaser introducing the actress' get-up. She will be seen sporting short hair, wearing a saree, in this exciting film.

The film will be directed by Anu Menon and will hit the screens next Summer (in 2020). "An extraordinary true story of the human computer," is the caption.

"Vidya's titular character has been etched to bring out Devi's sharp, arrogant, eccentric, ruthless, witty, outspoken nature," the makers say.

It will be interesting to see how much the film will collect at the box-office, especially after witnessing the success of 'Mission Mangal' and 'Super 30' this year.
