Siddharth Anand is gearing up for the release of his upcoming Hrithik Roshan-Katrina Kaif starrer Bang Bang and the director says that his film is a 'celebration of every emotion'. At the launch of the film's title track, Anand said, ''Bang Bang is a celebration of every emotion. It touches a high of romance, action, drama, humour, scale, visual appeal, stardom and also music. I don't think we could have any other title other than Bang Bang for it.'' Produced by Fox Star Studios, Bang Bang is slated to release on Gandhi Jayanti.
