The Kohinoor is the largest diamond known in the history of mankind. We have exclusively learnt that in the action entertainment film Bang Bang, Hrithik Roshan steals the Kohinoor. How he does it and why he does it, we will need to wait and see on October 2, but what we do know is that the cops of the world will be behind him and there is an Omar Zafar in the film, played by the one and only Danny Denzongpa, who will go to any extreme to destroy Hrithik. Let's see who will win between the two.
