Bollywood star Vidya Balan had confirmed and joined the sets of NTR's biopic. And the actress will be playing the role of NTR's wife Basavatarakam. Not just her but the audience are also excited and eagerly waiting for it. \u201cPeople knew of her but they didn\u2019t know her and that is interesting for me as an actor,\u201d Vidya Balan told in an interview.\r\n\r\nThe Vice President of India, Venkiah Naidu officially launched the biopic which is being directed by J Krish. Since there are no details about NTR's wife the actress is doing a thorough research.\r\n\r\nSources say that KV Vijayendra Prasad had given suggestions to change few scenes which have already been shot but the moviemakers are still in the discussion because there are chances of the budget to go up. The cast also includes Keerthy Suresh, Mohan Babu, and Sumanth playing Savitri, SV Ranga Rao, and A Nageswara Rao. Also, Rana Daggubati might be playing the role of NTR\u2019s son-in-law.\r\n\r\nThe biopic is being produced by Balayya, Vishnu Induri, and Sai Korraputi. Reports also say that the film might hit the screens for the next year's Sankaranthi.
