Ko is a 2011 Tamil-language political thriller directed by K. V. Anand and produced by V. Ravichandran under Aascar Films. The film stars Jiiva as Ashwin, a photojournalist; Karthika Nair as Renuka/ACS (a chief ministerial candidate); and Ajmal Ameer as Naveen Kumar, a politician, with supporting roles including Prakash Raj as the ambitious incumbent politician. Ko blends investigative journalism, political conspiracy, and romance, wrapped in a glossy commercial package — music by Harris Jayaraj, cinematography by R. D. Rajasekhar, and tight editing that keeps the pace brisk.
