A source close to the film tells us, "The second part of Once Upon A Time In Mumbai is going to be on a much bigger canvas and hence Balaji is looking at a top actress to play the female lead. It would be either Kareena or Vidya.
Mandakini's character needs an actress who can emote very strongly. Kareena and Vidya best fit the bill."http://hotmedia2010.blogspot.com/
