Sridhar used to spend his evenings with Gopu, driving along Marina Beach, Madras (now Chennai). Gopu asked Sridhar whether he would like to work on a comedy film. Sridhar, who was known primarily for dramatic films, thought the audience would not accept a comedy from him. He agreed reluctantly upon Gopu's insistence, and decided to produce a full-length comedy and originated the title, Kadhalikka Neramillai, which translates as "No time for love". The entire story and screenplay were conceived on Marina Beach; according to Gopu, "Sitting in Sridhar's open Herald, we discussed the script for days on end." The screenplay was co-written by Sridhar and Gopu. A. Vincent was hired as the film's cinematography and P. N. Sundaram for photography, while N. M. Shankar was chosen as the editor and Ganga as the art director. Thangappan and Mugur Sundar were the choreographers. Editor B. Lenin, son of director A. Bhimsingh worked as one of the assistant directors.
