"I didn't prepare for the film at all... This movie needed sincerity and innocence which I had lost. Both, 'Bajrangi Bhaijaan' and 'Prem Ratan Dhan Payo' will bring back my sincerity and innocence," Salman told reporters here.
The 49-year-old actor's recent box office hits have largely relied on his brawn be it "Dabangg", "Ek Tha Tiger" or "Kick".
Salman, 49, plays a Hanuman devotee in the upcoming Kabir Khan film, which also stars Kareena Kapoor Khan, Nawazuddin Siddique and child actor Harshaali Malthotra.
"The experience of shooting in Kashmir was incredible. Beautiful place beautiful people. We have such amazing places in our country and we don't want to shoot there. How silly of us? Quite a few films have been shooting there now. No matter how much you shoot in Kashmir, it's going to look fresh and beautiful," he said.
