 Menon was keen to make a trilogy of cop films, much like Ram Gopal Varma's trilogy of gangster films, and subsequently planned "Vettaiyaadu Vilaiyaadu" as the second in the series after "Kaakha Kaakha".The film narrated another episode from a police officer's life, that of an Indian cop who moves to America to investigate the case of psychotic serial killers before returning to pursue the chase in India.As per Menon's usual method for picking a title, he asked his associates for suggestions, which included the title of "Thadayaara Thaaka", which was later used for another film.
