After the success of Thangappathakkam (1974), Mahendran was approached by S. S. Karuppasamy who gave a letter written by writer S. S. Thennarasu in which he attached a short story and said Karuppasamy expressed interest to produce a film.[4] Karuppasamy chose Krishnan–Panju to handle the direction of the film.[5] Mahendran felt the short story did not fit the film format instead narrated a different plot which impressed them; however Mahendran posed a condition that Thennarasu's name will be credited for story while his name will credited for screenplay and dialogues.[2]
