Reason Why Tarak didn't act in NTR Biopic?

When NTR Biopic was announced, majority of Nandamuri fans expected Jr.NTR to be part of the prestigious film, at least for a small role. But Tarak was not opted for any role, instead Kalyan Ram has bagged a crucial role. Now Kalyan Ram explains the Reason Why Tarak didn't act in NTR Biopic.
Several rumors made rounds on the differences between NTR and Balakrishna and how the former stayed away from campaigning for TDP in the Telangana elections. However the audio launch event of NTR Biopic has put an end to many such rumors, where Jr NTR shared stage with Bala Krishna and is all praises for him.
Kalyan Ram speaking to a news daily clarified on many interesting things including why Tarak didn't act in NTR Biopic. Kalyan Ram says that there is no role for a star actor like NTR in the film, and it won't be fair to ask Tarak to play a small role with which fans might be disappointed.
"NTR is a star actor and he deserves respect for his stardom" says Kalyan Ram. He further reminds us how Balakrishna gave importance to NTR and invited him for the audio release event of NTR Kathanayakudu and asked him to unveil the songs.
