So much has been in the news over the past few month about Om Shanti Om, and especially the last couple of months. However, here are a few tidbits you may not know about the film:

The first story draft of Om Shanti Om was written on Andrew Lloyd Webber's letterhead.

Farah had gone to London in 2002 for the Bombay Dreams, the Bollywood-themed musical, and while there she stayed at Andrew's house. It was here that she penned down her thoughts on the film using his letterhead. However, she made Main Hoon Na first.

Except for some portions, the complete screenplay for OSO was written by Farah in a mere two weeks.

Farahwas keen to have Dev Anand in the Deewangi song, however, the actor declined the offer as he never does special appearances. Dev Anand explained that to date, he has always played lead roles and he did not wish to break his tradition. Therefore he politely declined the offer, giving his regards to Shah Rukh Khan and gave his best wishes to SRK and Farah for their film.

Sridevi is another actress who refused to be a part of the song because she wanted to appear in the song with husband Boney Kapoor. Unfortunately, Farah was only having actors and actresses appearing in the song so she could not be accommodated.

Farah also approached Aamir Khan to make a special appearance in the Deewangi song but he plead inability to shoot as he was busy shooting Taare Zameen Par. His participation in the OSO song would have delayed his own film and, then in turn his new film, the Ghajini remake.

Anil Kapoor also did not agree to become a part of the song. Anil feared that he would be made fun of, on the sets. Also, Anil didn't feel like being one among so many actors.

In addition to the amazing feat of having the huge cast in the song, Farah also convinced veteran music director Pyarelal to come off his self-imposed exile from the film music scene to compose a song for Om Shanti Om.

The song was created in nine shifts spread over three days. In LP style, the song's recording took place in rare style in today's age of digitally-arranged music. It was recorded with a 150-plus orchestra; 40+ different drums ranging from tabla and dhol to duff, 40+ violins and 22 woodwinds amongst other instruments were used for the song.

Good luck to all those involved with the film and too bad for Aamir, Anil and all the other starts who turned Farah down, for it is certain this is one song - perhaps even film - that will go down in cinematic history.
