Yesteryear action hero Arjun is all set to entertain with a thriller. Arun Vaidyanathan of ‘Achchamundu Achchamundu’ fame will be directing the film. Sharing the film’s secret, he says, "It is a stylish cop story with Arjun playing a cop who is very calm and composed. Usually the cops that we see in Tamil films are aggressive, but Arjun’s role will be different. The shooting will commence from August and we are planning to shoot in Chennai and Bangalore."
