Hrithik Roshan and Katrina Kaif could not create any bang on the box office with their film ‘Bang Bang’. The film was a copy from the Hollywood movie ‘Knight and Day’. The film ‘Knight and Day’ starred Cameron Diaz and Tom Cruise. Bollywood movie ‘Bang Bang’ was amazingly awaited by the masses, but the movie failed to create any spark on the silver screen. Not only was the concept loosely copied but the performances were also miserable.
