Abhishek was quite content with the clothes he was made to wear for the movie.

"It was a welcome change to not have so many different costumes. And most importantly it was the requirement of the film", said the actor.

To ensure that Abhishek's clothes look sparkling clean, the director had ordered 10 sets of kurta-pyjamas.

"Abhishek plays a young forward-thinking politician who follows in the footsteps of his father (played by Paresh Rawal)," said director R. Balakrishnan, fondly called Balki.

Paa is a sensitive story about the relationship between a father and son, who suffers from Progeria, which causes premature ageing.

The movie also stars Amitabh Bachchan and Vidya Balan in key roles.
