In 2018, the film director RDM, also known as Ranjith Manikandan, has zeroed in on the popular slogan,
Kavalthurai Ungal Nanban, for the title of his next film. Video jockey
Suresh Ravi was cast in the lead role. The film director and the actor had previously collaborated for a comedy caper titled
Adhi Maedhavigal in 2014, which was shelved before release. Talking about the film, Suresh Ravi said, "
KUN will be the first heavy-weight drama in my career. The film will play on the relationship dynamics between a police officer and a food delivery executive, who come together by chance. While I play the delivery boy, Mime Gopi will be seen as the cop. Our film will celebrate the real police spirit, which is, unfortunately, being shown in poor light in many films". In January 2020, the film producer
G. Dhananjayan had acquired all the rights of the film. == Reception ==
