/> Even as Balki puts finishing touches to the script for his third film featuring the Big B in the lead, the twosome who gave us the two extremely unconventional hits Cheeni Kam and Paa will now be getting together for a 15-minute film celebrating 100 years of Indian cinema.

While details for the project are yet to be finalized it is understood that PVR Cinemas has commissioned 8 leading filmmakers to make 15-minute films which would all be released as one feature film in 2013 when Indian cinema celebrates a 100 years of existence.

The first director to start his film would be Balki.

Says the director, "Doing a short film with Amitji would be a special challenge for me because I've never done a film in that format before, and neither has he. We've done numerous ads and two feature films together. Now let's see what I can do with Amitji in the 15 minutes that we'll be provided."

Balki says another film with the Big B, no matter what its duration was imperative. "I was beginning to get withdrawal symptoms. That man is addictive. Once you work with him there's no way you can resist working with him over and over again."

While the challenge of creating a 15-minute full and comprehensive film replete with a plot and a background score will be taken up by Balki in the pre-winter months, at the end of the year he'll start his third feature film with Mr Bachchan. Apparently it would be the Big B's most intensely romantic film since Yash Chopra's Kabhi Kabhie in 1975.

And no, this time there would be no Abhishek Bachchan.
