Hrithik Roshan and Katrina Kaif at Bang Bang title song launchHrithik Roshan and Katrina Kaif launched the title track of their film 'Bang Bang' today. The foot-tapping number has Hrithik performing an ode to none other than the late Michael Jackson. Hrithik spoke about this saying, "I did this song for the love I have for MJ. When you do something for love, it's always great!" He added, "We all go through challenges & I'm the kind of person who enjoys it." Since the Shahid Kapoor movie 'Haider' is also releasing on the same day along with 'Bang Bang', Hrithik said, "2nd October will be the day when two films will do exceptionally great." Hrithik was all praises for his director when he said, "We have worked very hard for this film but this movie belongs to only one man, Siddharth Anand. Bang Bang is going to be one of my best movies." Katrina Kaif spoke about the title track saying, "Hrithik's part in the Bang Bang title track is sensuous." She added, "I've done a different kind of action in Bang Bang.
