Pawan Kalyan is coming up with Bheemla Nayak in a week. After that he has Hari Hara Veera Mallu with Krish and eventually Harish Shankar's "Bhavadeeyudu Bhagat Singh" is also in line.
Sources say that Pawan Kalyan gave a strict caution to Haish Shankar to maintain poise on social media and not get into arguments with any one.
He advised him not to get into tweet wars with anyone with a desire to have the last word and win the argument.
It is known that recently Harish had a tweet tiff with writer and director BVS Ravi in the matter of sharing some political ideologies on a subject.
Pawan Kalyan may be concerned that any differences with any group in the film industry may affect his film and may attract trolls down the line.
