Balakrishna is taking all the pain in selection of casting for his dream project, NTR biopic. Few days ago, it was announced officially that Vidya Balan is acting in NTR biopic. But, Vidya Balan has kept the offer pending for a long time without giving reply. Later it is learned from sources that Balakrishna visited her house in Mumbai and explained her about the importance of the character of Basava Rama Tarakam, the wife of NTR and then Vidya Balan agreed. This shows how prestigious the movie is to Balakrishna and his efforts as well.
