Katrina Kaif got injured during the shooting of the movie Bang Bang at Mumbai. She was injured while taking a dance sequence with Hrithik Roshan. The steps were quite tough. The shooting had extended for about 14 hours and as a result none got rest. Though the shooting has been stopped for sometime as Katrina had been suffering from pain in her legs, it resumed soon. The set produced for this song shoot is highly costly. Therefore Katrina’s injury might affect the production cost drastically.
