Sujoy Ghosh approached Twinkle Khanna for the film. She declined as she had quit films. She recommended her sister Rinke Khanna take the film. It was Sujoy Ghosh's directorial debut. The film pays tribute to the legend RD Burman aka Panchamda. The music album, one of the best hits ever, made huge stars out of Vishal and Shekhar. The music was rejected by every major music company. Finally, BMG Crescendo released it.
