Ranbir Kapoor says he has been offered the movie based on Chetan Bhagat's bestseller "Two States", but the papers have not been signed yet.

"I have been offered 'Two States' but officially no papers have been signed.

We will work it out, but things need to be put down on paper," said Ranbir, who is gearing up for the release of his much talked about movie "Rockstar".

"Chetan is a very talented author that India has and it would be a new challenge for me to delve into a character that has already been popular among the masses in the form of book," he added.
