The film is set in the 70s Om Shanti Om, is about a struggling actor, who falls in love with a successful actress.But the struggling actor dies in an accident. He has another chance of finding his loved one in his next life this time as a big star. For those thinking gleefully that the song is another example of the Shah Rukh-Amitabh famed rivalry, it may be a bit of disappointment to know that both the Bachchans are very much in the film. Bachchan's presence in Om Shanti Om, a Shah Rukh Khan home production, puts an end to speculation about the animosity between the two stars. The stories of their supposed rivalry intensified after Shah Rukh became the host of STAR TV's quiz show Kaun Banega Crorepati, which was till then known as Amitabh's show, and ran it in his own style successfully. Soon after that, he acted in a cheeky remake of Amitabh's 70s hit Don, adding grist to rumour mills of the bad vibes between the two superstars. Then followed Ram Gopal Verma dropping his Time Machine with Shah Rukh in order to complete his two projects with Amitabh - Nishabd and Ram Gopal Varma Ki Aag. Despite being in London at the time of the International Indian Film Academy (IIFA) awards function in Yorkshire, Shah Rukh gave the event a miss. In fact, he missed the 2006 IIFA function too. The reason was said to be Bachchan being the brand ambassador of IIFA. At the time Amitabh was unwell last year, Shah Rukh bagged many of his ad assignments - with ICICI Bank, Navratan Oil and the government Pulse Polio ads.Although Amitabh has often denied any rivalry, he didn't invite Shah Rukh for his son Abhishek's wedding with Aishwarya Rai. Perhaps Om Shanti Om marks a new friendly beginning for both
