Asked if she has signed the film, Anushka said: "I can't talk about it till its confirmed. The announcement will come at the right time. I am looking forward to working with Anurag Kashyap."
The movie is said to be based on Mumbai Fables, a semi-fictional study of Bombay in the 1960s by Gyan Prakash, who is a historian and professor of history at Princeton University.
Actor Ranbir Kapoor has been finalised to play the male lead in the film.
"I have completed shooting for the film. I was very happy to work with Vishal Bharadwaj. He makes very different and true films," she said.
"All the characters are very well-written. Each character has a well defined beginning and end in the story," added the 24-year-old.
The movie is likely to release next year.
