After the sad debacle of Kites, Anurag Basu is working on an even more difficult subject. Basu's next is titled 'Burfee' and will star Ranbir Kapoor, Priyanka Chopra and Telugu actress Illeana D'cruz. Anurag agrees that working on the film will not be easy because all the three characters he has sketched for the film are quite challenging. Priyanka plays a deaf and dumb girl in the film that was about to get rolling on March 10. But the lady has asked for ten days more before she starts shooting to prepare herself for the role. Ranbir Kapoor too would be playing a mute and fat guy in the film and will put on extra kilos for the role. Even Illeana will be put through rigorous practice of hindi diction before the movie starts rolling. Well, seems like this time Basu does not wants to take any chances from the beginning.
