How did Paa happen?

The director Balki one day came to us with the script, which I have not read so far, and told us, ‘I want you to play father and son.’ And I was like, ‘What’s new in this?’ Then he added, ‘I want you to play the father and Amitji to play your son.’ It was an opportunity of a lifetime. All I had to do was be his best friend, which we are in real life. And I enjoyed playing Paa’s Paa.

What was your first reaction when you saw Amitabh Bachchan on the sets with his make-up on?

I didn’t recognise him! My dad and Vidya Balan were shooting near our home and Balki asked me to drop by. I was mingling with the people there and then I asked Balki, ‘Where’s dad?’ And dad called out, ‘Next to you.’ I was stunned at the way he looked and behaved. He had transformed into a 13-year-old.

You sport just one costume in the film.

I was happy since I did not have to change. Coming from a film like Dostana, where all I had to do was change costumes, this was cakewalk. But then Balki took his revenge in a song where he made me wear 17 different costumes.

You play a politician in the film. Did you derive inspiration from someone?

Yes, from two of my good friends, Milind Deora and Sachin Pilot, but only the physicality.

What was the wackiest thing that Amitabh Bachchan did as a kid in the movie?
