Mumbai, Nov 5 (ANI): The fist-look of movie 'Paa' was released here on Wenseday.

The movie proved the role reversal of Bollywood's most renowned father-son, Amitabh and Abhishek Bachchan in the reel life.

The 67-year-old actor Bachchan would be playing the role of a 13-year old boy, diagnosed with Progeria.

His real life son Abhishek is playing his father's character in the movie.

"In childhood he used to make me sit on his shoulders. I always have a lot of fond memories of looking down upon everybody because I used to be sitting on my dad's shoulder as kid, and it was wonderful to repay the favour," Abhishek told reporters.

Amitabh Bachchan's fans would also have doubts in recognising him after seeing his bald look wearing school uniform in the poster and promo of the movie that was unveiled.

"Balki (Director) when he set the look of the film, felt very strongly that whatever performance Paa comes out with, it should be something we have never seen Amitabh Bachchan do before. And like he said that before, that he has worked very hard to remove Amitabh Bachchan from Amitabh Bachchan.

So he thought it was very apt to say 'introducing Amitabh Bachchan' because here's a whole new Amitabh Bachchan, nor does he look differently, he will behave differently and act differently and speak differently," said Abhishek

R. Balki, Director of the movie said the difference in the real and reel life characters would make the movie dissimilar and appealing.

Bachchan plays a boy named 'Auro' who actually looks 25 odd years older than him due to the genetic disease. The film has already gained palpable excitement among the audience due to real life role reversal.

'Paa' is set for release on November 13. (ANI)
