Amitabh and Abhishek Bachchan in Balki's 'Pa'

Abhishek Bachchan’s term of endearment for Big B will now be the name of a film, starring the father-son duo.

Apart from Ram Gopal Varma’s Sarkar 2, superstar Amitabh and son Abhishek Bachchan are all set to star together in yet another movie.

Balki, the maker of Cheeni Kum, starring Amitabh Bachchan and Tabu, has already signed the father-son duo for his next film called what else, but ‘Pa’!

Abhishek calls his dad 'pa' in real life too. Apparently, Big B was very impressed with Balki during the making of Cheeni Kum, which is the story of a younger woman falling for a much older man.

The buzz is that RGV was inspired by Balki’s story; he made Nishabd on the same topic and released it even before Balki could complete his film. However, Balki’s new film Pa will be a light comedy .The female lead has not been decided as yet.

When contacted, Balki confirmed that he is indeed doing a film with the Bachchans. He said, “Pa is a comedy and both Amitabh and Abhishek loved the script when I narrated it to them. We have not worked out the dates as yet since the shoot will only begin after the release of Cheeni Kum which is scheduled to release on May 25th.”
