M. G. Ramachandran and
Sridhar earlier were supposed to work in a film called
Andru Sindhiya Ratham which got shelved. According to Sridhar, the reason for Ramachandran backing out may have been that, since Sridhar launched both
Kadhalikka Neramillai (1964) and
Andru Sindhiya Ratham at the same time, he promoted
Kadhalikka Neramillai as the first contemporary colour film in Tamil but did not do the same for
Andru Sindhiya Ratham, which may have made Ramachandran upset, causing him to leave. Sridhar, who was reeling under financial problems due to failure of his previous film
Alaigal and also his other film
Vaira Nenjam was getting delayed due to call sheet issues of
Sivaji Ganesan, as per the advice of his friend, the Hindi actor
Rajendra Kumar, decided to collaborate with Ramachandran who agreed to act under his direction. Sridhar revealed that
Urimai Kural was inspired from the
Telugu film
Dasara Bullodu (1971); he took only the basic plot from that film and made changes for Tamil version. When Gopu saw the film he suggested Sridhar to do this film with Ganesan however Gopu was shocked when Sridhar said he would make this film with Ramachandran. Gopu who received opportunities as director after the success of his debut directorial
Kasethan Kadavulada (1972) wanted to concentrate on directing films, which led both of them to part ways professionally but still remained friends. The cinematography for the film was handled by N. Balakrishnan; however the climax portions were shot by Thambu as Balakrishnan had to shoot the climax for another film. The film was predominantly shot at a village Mugalivakkam near the garden belonging to Ramachandran while the climax portions were shot at land belonging to actor-producer
K. Balaji and the songs were shot at Mysore. == Soundtrack ==
