Darsaka Ratna Dasari Narayana Rao gave life to many people in Tollywood but could not establish his son Arun Kumar as an actor. Arun didn't get recognition though he acted in few movies earlier. Arun Kumar is given a chance to act as villain in Allu Sirish's movie which is going to be released on December 23. Now he got another chance to act in a prestigious project, the 151 movie of Chiranjeevi,'Sai Raa'. His acting career will come on to tracks if he gets success in these movies.
