Actress Rani Mukerji is returning to the big screen with "Hichki", which she says is built on a positive response.

Filmmaker Vidhu Vinod Chopra says that he, along with writer Abhijaat Joshi, is working on the script of "Marco" -- which will be actor Sanjay Dutt's comeback movie -- and that the project will go on the floors in the first half of next year.
