It was a tough role reversal for Abhishek Bachchan who plays father to Amitabh Bachchan in Paa but the young actor chooses to train the spotlight on Big B, saying that the veteran has delivered his best performance till date in the film.
"Paa will be his best performance till date but at the same time with every character Paa plays, he improves and gives his best. I would say that he always comes out with his best till date with every new role," Abhishek told PTI in an interview.
The 34-year-old had earlier created a world record for covering the most number of cities in a promotional tour for Delhi 6 and now he becomes the first actor to play reel life father to his real life father, megastar Amitabh Bachchan, in their home production.
But the actor chooses not to bask in that glory and says that it will be his father's best performance till date.
In the movie, director R Balakrishnan, has presented the 67-year-old megastar as a child suffering from the rare disease of progeria, which makes him age fast.
Abhishek said that he instantly agreed when Balki narrated him the story as it was a lifetime opportunity for him.
"When Balki first told me, 'I want you to play father and son' my first reaction was 'What's new in that?', he then added 'I want you to play the father and Amitabh Bachchan the son'. This was an opportunity of a lifetime," he said.
