Nagarjuna is not on talking terms with Balayya and this has been proved in many times previously. Even he did not say much about the biopic of NTR when the film released a week back in Telugu.
Now, the matter is that Nag is verbally upset with the manner in which the biopic and his dad has been showcased in the film playings second fiddle to NTR in all the scenes.
There is also a talk that Nag is upset over Sumanth doing ANR’s role and has given him first-hand treatment saying how did he approve of many digs which were taken at his dad in the film. That is the reason he has not seen the film or has at least tweeted about it.
