Tollywood actor Naga Chaitanya was not exactly overwhelmed to play the role of the colossus of Telugu film, his grandfather, Akkineni Nageswar Rao, in Mahanati. When asked he wanted to somehow excuse himself out of it. But today Chaitu is proud to have played that role of his lifetime. He relates how he tried to get into the feet of his grandfather. Director Nag Ashwin too convinced him about the role that has hardly two minutes screen time. Naga Chaitanya said that he is happy to be in such a content-oriented film, which the audience have cheered lustily.
