Bollywood superstar Amitabh Bachchan has got the perfect bahu in Aishwarya Bachchan. She is more than happy to help out her father-in-law in times of need. As if taking up the responsibility of marketing Paa is not enough, she has decided to take a break from the shooting of Guzaarish to help with the premiere of the film .With Jaya Bachchan currently attending parliament, Abhishek Bachchan busy shooting for Ashutosh Gowariker's film and Aishwarya shooting for Sanjay Leela Bhansali's Guzaarish, Amitabh Bachchan is running around to put the premiere of Paa in place, which is taking place on December 3. Seeing this, Aishwarya has decided to help him before the premiere.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, he has given a few days off to Aishwarya so that she could help her father-in-law in arranging the premiere of Paa. Bhansali said that it's not a big deal to readjust the shooting of his film for someone, who has been a dear friend for many years. He added that it was not done for Aishwarya but for Paa and Amitabh, as it's a special moment for the Bachchan family.Paa, which is releasing on December 6 marks the return of AB Corps Ltd into filmmaking after a long hiatus. It features Amitabh, Abhishek Bachchan and Vidya Balan in the lead roles.
