Cinematographer Natty had a great hit of ‘Sathuranga Vettai’ last year and this success had gradually made the producers and distributors to earnestly look up for his forthcoming ventures. One among them was ‘Katham Katham’ that had gained a remarkable prominence with the Sathuranga Vettai success. The film is directed by Babu Thooyavan and Sri Thenandal Films has decided to release it by end of March. The film is based on the concept of Superstar Rajnikanth’s yesteryear release ‘Ranga’, where two men on other sides of good and bad get influenced and have their lives changed. Similarly Natty is a fraud cop who keeps Nanda to come his side, who is an honest police officer, but as the time proceeds the tables change the sides.
