Hrithik Roshan and Katrina Kaif are on a roll with the shooting of her much hyped film 'Bang Bang'. The movie is a remake of Hollywood film 'Knight And Day'. And now it seems that the budget of this starry film has gone much overboard. According to reports, the financials of 'Bang Bang' have crossed 100 crore. And it may get difficult for the producers to make the movie a profitable venture. 'Bang Bang' has been shot in exotic locations like Kashmir with currently shooting in Abu Dhabi. The film was also delayed a bit because of the major injury suffered by Hrithik while performing action sequences.
