48-year-old Rahman, who is the subject of Discovery Channel's special program "Jai Ho", said there were a lot of offers to make a documentary on him before too.
"There were a lot of offers before too to make a documentary on me but I thought that was unnecessary. But after the Oscar happened, I felt people could get some kind of inspiration through the journey of my life and the way I make music," Rahman told reporters here.
The 90-minute documentary, directed by Umesh Aggarwal, chronicles the life and rise of the "Tamasha" composer.
Rahman said the documentary, which was initially meant for consulates, was like an introspection for him.

"It's a very understated documentary it's not trying to make a big thing. It's got it's humour, music making and it's not even me, its about people talking about me.... So you're rediscovering yourself like, 'Oh wow really?'"
"Umesh contacted me and initially said its only for consulates all over the world so I thought less exposure, which is good... But I didn't know it'll (documentary) turn out charmingly... Because I hate to watch myself, I do."
The documentary features interviews of "Slumdog Millionaire" director Danny Boyle, lyricist Gulzar, actor Aamir Khan, filmmaker Mani Ratnam, Ashutosh Gowariker, composer Andrew Lloyd Webber among others.
"Jai Ho" will premiere on October 26 at 9 PM.
