 Initially the director revealed that the film titled "Adhu Oru Kana Kaalam" would be an extension to his 1979 film "Azhiyadha Kolangal" stating that Dhanush would play a teenager infatuated by a woman who is fifteen years older than him to be played by Ramya Krishnan.However he opted against doing that story and decided to build his film around two of his Malayalam films from the 1980s – "Nireekshana" and "Yathra", and the title of the film was subsequently changed to "Unakkae Uyiranaen".It was later changed back to the original title before release.
