Aishwarya Rai goes all out for her father-in-law Amitabh Bachchan. She is more than happy to help out in the times of need, and that is why she has put aside all her present commitments just to be with daddy-dearest and hubby-Abhi during the premiere of Paa and its release.
Aishwarya was committed to shoot for Sanjay Leela Bhansali's Guzaarish but has taken a few days off from the shooting. Bhansali, who is known for strict discipline, punctuality and schedules, relaxed a bit for the Bachchans. In spite of knowing the fact that stopping the shooting of Guzaarish even for a couple of days could disrupt its entire schedule.
Paa, releasing on December 6 marks the return of AB Corps Ltd.

What is Paa all about?
Auro (Amitabh Bachchan) is an intelligent, witty 13-yr-old boy with an extremely rare genetic defect that causes accelerated ageing. He suffers from a progeria-like syndrome. Mentally he is 13, very normal, but physically he looks five times older.
In spite of his condition, Auro is a very happy boy. He lives with his mother Vidya (Vidya Balan), who is a gynecologist. Amol Arte (Abhishek Bachchan) is young, progressive and a full of ideals politician. He is out to prove to the world that 'politics' is not a bad word. He is a man with a mission. Auro is Amol's son. Paa is a 'rare' story about a father-son, son-father relationship.
