Shah Rukh Khan wanted his Main Hoon Na co-star Amrita Rao to be a part of the special song too. But director Farah Khan, we learn, had bigger plans. She wanted to have a complete Main Hoon Na segment in Deewangi song. That is to say she had hoped to have Main Hoon Na’s leading cast Sushmita Sen, Amrita Rao and Zayed Khan along with SRK to be featured together in a separate part of the song. Amrita says, “I couldn’t shoot for the song as I was busy shooting for Athidhi in Austria. Farah would call me up every time and badly wanted Sushmita, Zayed, Shah Rukh and myself to do a Main Hoon Na sequence but I just could not get out of my schedule.” And Farah went ahead with only Zayed and Shah Rukh where they do their trademark ‘head rubs’ from Main Hoon Na.

Apart from A’s - Amitabh, Abhishek, Aamir and Amrita, there were others too who missed out. Among them were Dilip Kumar and Saira Banu who were the only senior actors who could not make it for the song though Shah Rukh and Farah wished for it desperately.

Shah Rukh who was initially tagged of having a strong Dilip Kumar hangover has always looked up to the senior Devdas as his idol.

From the yesteryear celebrities, King Khan also wanted his personal favourite Zeenat Aman to add grace to the song. Not to forget Zeenat’s popular costar - the style icon Feroz Khan. Plus his son Fardeen Khan! But both father and son were out of town. So Shah Rukh says that what you saw in Om Shanti Om was not big - at least not as ‘magnanimous’ as he and Farah had visualized it to be, though for the audiences this was as grand as it could get. The king feels that if he could manage to get all the ones they had planned for that could have been huge. So SRK says, “Now I feel I will have to make a sequel to Om Shanti Om and request all the celebrities who missed out from the original song to shoot a song with me in the sequel”.
We would eagerly wait for ‘OSO 2’, Shah Rukh!
