The 1990 film fetched Amitabh his first National Award.
"I wish him good luck. I think it's a very brave thing to do. If you think of top 10 characters of Hindi cinema, Vijay Dinanath Chauhan is up there. It's difficult but I have immense respect for Duggu (Hrithik) as an actor, " Abhishek told.
"He knows his job very well. So, obviously, he will sort it out. He's not going to take on anything on whim or fancy. I am pretty sure they have a different interpretation of the entire story altogether, " he added.
Yash Johar produced the original "Agneepath" and the remake would be produced and directed by his son Karan Johar.
Abhishek feels that Big B's film shouldn't be remade frame by frame, as it would put huge pressure on the new actor.
"I think with 'Paa', you should not remake his film directly scene by scene because he is too iconic an actor. I feel that for most iconic actors. I feel it becomes a huge burden for the new actor to do. If you have a different perspective on it, like I think when Shah Rukh Khan did 'Don', they had a completely different perspective of the original one, " Abhishek said.
Abhishek rubbished all speculations that he was approached with the role before Hrithik. "I was never asked, " he clarified.
