Young tiger NTR is back in his comfort zone.We are talking about his upcoming film 'Dammu', under the direction of hat-trick director Boyapati Seenu. NTR is known for his high votage action entertainers. Over the past few years, NTR tried to re-invent himself by choosing diverse roles which would cater for a wide range of audience. But for Dammu, the young actor has decided to stick to the basics. This film will remind us of NTR during the days of 'Aadi' and 'Simhadri'.
