The 2014 actioner, directed by Siddharth Anand, is the story of bank receptionist, Harleen Sahani’s (Katrina Kaif) chance encounter with a mysterious charmer, Rajveer Nanda (Hrithik Roshan) leading to an adrenaline-fueled, transcontinental adventure. “Bang Bang is the first film in which instead of getting into the character, I discovered that I was the character. It was self-discovery,” Hrithik had said in an interview earlier and anyone who has watched this remake of the 2010 Hollywood film ‘Knight and Day’, knows he is not exaggerating when he says that.
