Actress Taapsee Pannu says living with world's oldest sharp shooters, Chandro and Prakashi Tomar, to prepare for her role in Saand Ki Aankh has left a lasting impression on her. Saand Ki Aankh will narrate the real-life story of Chandro and Prakashi, who hail from Johri village in Uttar Pradesh and reportedly took to sharpshooting in their fifties. They are said to be the world's oldest female sharpshooters, and while Chandro is fondly called Shooter Daadi, Prakashi is known as Revolver Daadi.
