"Paa" is an upcoming Bollywood movie starring superstar Amitabh Bachchan, Abhishek Bachchan, Vidya Balan, and Paresh Rawal. The details of the film have been kept underwrap, but believe it or not - Abhishek plays the role of father and Amitabh plays his son! The production company flew in a special make-up team from London just for Amitabh's new look. It took the make-up team 4 hours to apply the make up and close to 3 hours to remove it.

Paa is to be released worldwide on December 4th, 2009.
