Vidya Balan is presently busy shooting for Cheen Kum fame R. Balki's Paa. And from the looks of it she seems to be having a ball shooting the film.

States Vidya, "See it has been a dream come true for me to work along side Amitji (Amitabh Bachchan) and once again with Abhishek after Guru.

Both are pretty chilled out on the film's sets and never make me feel that we all are working together for the first time. Both are very easy to work with and very cooperative. Abhishek is extremely hilarious.

Working with the both of them was a nice experience. I am amazed by Amitji's patience on the sets. He definately deserves to be called the father of our industry."

Revealing futher the pretty actress adds, "The most interesting thing about the film is that Abhishek Bachchan plays the role of the father while Amitabh Bachchan plays the son.

My character comes as the surprise package of the film. We still have a schedule pending as there are a few songs and scenes left to be shot. I am confident that film be loved by all when it releases, hopefully by the year end."
