Special screening of Amitabh Bachchan's new film "Paa" was staged for hearing and speech-impaired children here on Monday.
In this unusual film, Bachchan plays Auro, a teenager afflicted with progeria, a rare genetic condition that causes a person to age faster than normal.
The film, however, focuses on the relationship between father and son, and doesn't talk about the tragic life of a progeria victim.
"I think it was wonderful thing ...screening for our hearing-impaired children and whatever we can do, we would love to do, and it has been an absolute pleasure and to be able to share these moments with the kids. It gives us lot of happiness," said Abhishek Bachchan.
On being asked whether playing "Auro" was a challenge, Amitabh Bachchan said that an artist likes such challenges.
"I believe that every character is a challenge for us; it is good luck if challenges come before an artist.
I believe that an artist should never be satisfied. If he (artist) is ever satisfied, then our inner artist would die. So I believe that challenges should come before us everyday, and I think somebody should think of more and bigger ones for me in the future," he said.
He said he was intrigued by the fact that he would play his own son's son, however Abhishek said he deliberately distanced himself from that real-life relationship.
