Keeping beside his busy schedule, Ranbir Kapoor has joined the team of Bombay Talkies. The film celebrates 100 years of Indian cinema. It comprises four different short films each of which has been directed by Karan Johar, Dibakar Banerjee, Anurag Kashyap and Zoya Akhtar. Incidentally, this is the first time that the four prolific directors have come together for a movie. The film will have Ranbir as the <em>sutradhar</em> (narrator); his character will tie the four short films into one film.
