After
Ilaiyaraaja finished composing the songs of
Kaakki Sattai (1985) in half-a-day, well before the three-day schedule, he started to compose other songs since he was free at that time; he ended up composing six songs, hoping to use them in a potential film. Producer-lyricist
Panchu Arunachalam, who used to listen to Ilaiyaraaja's unused songs and pick any of them he liked for future projects, wanted one of the six tunes for the film that would become
Vaidehi Kathirunthal. But Ilaiyaraaja insisted that he listen to all six tunes; the producer did so, and the storyline of
Vaidehi Kathirunthal was developed based on them. The title was derived from a line from the song "Vasanthathil Orr Naal" from
Moondru Deivangal (1971). The film was written and directed by
R. Sundarrajan, and produced by Thooyavan under Appu Movies, while Arunachalam was credited as presenter. Cinematography was handled by Raja Rajan, and editing by M. Shrinivasan and B. Krishnakumar.
Anitha Kuppusamy was initially offered to be the lead actress, but she declined, citing a lack of interest in an acting career; the role went to
Revathi. This was the Tamil debut of
Kannada actress
Pramila Joshai (credited as Parimalam), and the feature film debut of
T. S. Raghavendra (credited as Raghavendar) and Sivankumar. == Soundtrack ==
