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.

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.
