Director K Raghavendra Rao is credited to being the pioneer of commercial cinema in Tollywood. The ace director has earned the nickname “Darsakendrudu” (best among the directors) for his pioneering contributions to Telugu cinema ever since his debut in 1975. The veteran director has turned seventy today. Born into an agricultural family in 1942, he made his debut with Babu, back in the mid seventies. Since, he has grown to become one of the most prolific filmmakers ever directing over 100 Telugu films. Only Dasari Narayana Rao has directed more films than he has. The director has been focusing more on mythological films off late. He is currently working on Shirdi Sai Baba starring Nagarjuna in the lead. The film is expected to release in a month.
