We have seen films on mentally retarded people. But Balki's PAA, starring Amitabh Bachchan, Abhishek Bachchan and Vidya Balan, goes one step ahead. For the first time we'll come across a patient, who is suffering from a rare kind of disorder called progeria, a debilitating disease where the child ages rapidly beyond his age. And this complicated character is played by none other than our very own Amitabh Bachchan. Big B plays a 13-year old child Auro in Balki's PAA.

Recently when the first look of the film was launched, everyone was taken aback watching Big B. Those who saw the rushes of the film are already going gaga over Amitabh Bachchan's role in the film and touting it as Big B's most happening film ever. Further what makes it all the more special is son Abhishek playing the reel PAA of real life paa Amitabh Bachchan.

When we asked Abhishek how it feels playing PAA to his own father on-screen and the first-feeling when he heard the word 'paa' from his father. Overwhelmed Abhishek replies, "It feels really great. Fantastic. Yes, initially it was a bit weird to hear dad calling me 'paa', but at the same time it was a wonderful experience. Experience of a lifetime. (Laughs) I got to bully him after 33 years." Further on asking how was Big B as a child, to which Abhi jokingly concludes, "Amitabh was a very troublesome child all through the film."

Hmm...so get ready to play with 13-year old Amitabh Bachcha(n) oops Auro this December 4th!
