Srihari said that he narrated the storyline of BAN to Pawan but he did not agree to play the role of Chief Minister of Andhra Pradesh. He liked the subject but said that it would send wrong signals to people that he is floating party for the sake of power. So he rejected the offer.
Koratala Siva who wrote stories by himself for all 3 movies earlier, now bought the story from Srihari Nanu for his 4th movie BAN in which Mahesh is essaying the role of CM and Bollywood beauty Kiara Advani is essaying Mahesh PA.
Earlier during an interview, Puri Jagannadh also revealed that Idiot, Amma Naanna O Tamil Ammayi and Pokiri were all written for Pawan but he rejected.
