Just before 'Paisa Vasool' movie announced, it was reported that Nandamuri Balakrishna got ready to team up with Krishna Vamsi for 'Rythu'. Balayya liked the script but he agreed to do the film with Krishna Vamsi on one condition that Amitabh should essay the role of The President in the film. They have met Big B on the sets of 'Sarkar-3' and narrated the story and the importance of his character in the film. But Amitabh politely rejected the offer.
No one really knows why did he reject 'Rythu' offer but there is a new version doing rounds for rejecting the offer that Amitabh liked the story and his character in 'Rythu' but he didn't take up the role because PM Narendra Modi actually wanted to nominate Sr.Bachchan for the President or Vice-President post at that time. Somehow Amitabh couldn't occupy the prestigious posts in real life.
Some say that Amitabh might give a green signal to Balayya film now as the Presidential election is over. We have to wait and see whether Balayya-Krishna Vamsi will approach Big B again or not.
