It is known fact that Tollywood actor and MLA, Balakrishna is bringing out a biopic on his father and former chief minister, N.T.Rama Rao. For this he has practised the signature of the founder or Telugu Desam Party (TDP). This fact came to light recently, when Balakrishna visited Telugu Desam Legislative Party (TDLP) office. He met minister Adinarayana and some other party MLAs. When they urged him to sign some papers, Balaiah first tried his signature on a piece of paper. On asking why, he said that for the biopic he had learnt to sign like his father and did not to make mistakes now.
