Abhishek's experience as his father's father in Paa

Abhishek Bachchan, who in a unique turn plays father to dad Amitabh Bachchan in Paa, states that shooting for the movie was an exciting journey everyday.

“It was a wonderful experience more so because I have been calling him Paa for the last 30 years and here I am his father. I took advantage of admonishing him on the sets. I was asking him to eat his food on time and go to bed on time. Only when his make up was off he was my Paa again. The relationships we are exploring here is different. Paa is a trip," he says.

Abhishek adds, “All the paternal instincts in the roles have been references of his own childhood. My Paa often carried me on his back. Now I am carrying him on my back in the movie. I have tried to as good as him. Paa was very naughty on the sets. He had a whale of a time playing a kid in the movie."

“What I was surprised was at the energy with which he attempted the role. He was fantastic. He has also sung a song in the voice of a 13 year old. I don"t think anybody will be able to match up-to him," he concludes.
