Well, doing action scenes on screen is not just about looking tough. But also about being a toughie - physically, and mentally. Ace action choreographer Sham Kaushal admits that he was amazed with Priyanka Chopra's perfect execution of the most daring fight sequences in Prakash Jha's Jai GangaaJal, in which she plays a righteous top cop. The action-director, who has worked with Priyanka in her earlier films as well, says that her strength to pull off the most dangerous stunts convincingly comes from a rare combination of physical fitness and mental strength. “In this film, I made Priyanka do the same action that I would make any hero do. She is physically very fit, but it's her mental strength that sees her through. To be able to pull off this high level of action, you need to be physically strong, but it is more important to be mentally stronger, and Priyanka is just that. She insisted on doing all the action on her own and that is commendable. She is so confident that she can pull off any action scene very convincingly,“ he explains.
