Nana Patekar became a well known face in Indian Cinema with eccentric roles and proved his versatility with comic roles too. He is doing character roles in Hindi but never anyone could bring him to Telugu.
In fact, Kaala is his first South Indian film and he did it to act with Rajnikanth and then there were no talks about him doing another film in Telugu or Tamil. But Trivikram Srinivas has a inkling to bring these big actors to Telugu and he is trying for Nana, in his next it seems.
Allu Arjun who also likes a challenge, did give the director a free hand to choose actors and the sources claim that there are many characters and we might see bigger ensemble than S/O Satyamurthy in this film.
Nana Patekar could be the big villain of the subject and the director is more than likely to meet the actor and give a narration of the story, it seems. Once, they meet and Nana listens to the story, rest depends on the negotiations as Nana is willing to work with Trivikram Srinivas it seems.
