For the theme song in Viacom 18’s Bombay Talkies which features stars, old and new, living and deceased, and footage from vintage classic films, choreographer Vaibhavi Merchant had to seek and obtain as many as 80 NOCs (No Objection certificates) from producers whose clippings have been used for the number. Apparently Vaibhavi had to convince each producer to part with the footage required for the song.

Following Katrina Kaif who did a lavani number in the Hrithik Roshan-starrer Agneepath and Vidya Balan who danced to a lavani number in Vidhu Vinod Chopra’s recently released <em>Ferrari Ki Sawaari</em>, Rani Mukerji has picked up the cudgel and has finished shooting for a <em>lavani</em> number in director Sachin Kundalkar’s <em>Aiyya</em>. The song has been choreographed by Vaibhavi Merchant.
