Production Development Parasakthi was a popular 1950s Tamil play written by Pavalar Balasundaram, a Tamil scholar. Around the same time, En Thangai (My Sister), written by T. S. Natarajan, became popular. Sivaji Ganesan, at that time a struggling stage actor, acted in En Thangai as "a brother sacrificing his love for the sake of his sightless kid sister." The pre-production crew at Central Studios, Coimbatore, initially planned to merge these two plays to make a film. However, Natarajan disagreed with the idea, and sold the rights of the play to another producer. En Thangai was made into a film with the same name. Later, film distributor P. A. Perumal of National Pictures, with the patronage of A. V. Meiyappan of AVM Productions, bought the film rights of Parasakthi. The duo Krishnan–Panju were signed on to direct at Meiyappan's suggestion, and M. Karunanidhi, who would later become the Chief Minister of Tamil Nadu, was signed to write the script. The cinematography was handled by S. Maruti Rao, while the songs were choreographed by Heeralal. Panju edited the film under the alias "Panjabi". Casting and filming Ganesan, the stage actor of En Thangai was chosen to play the male lead, making his cinematic acting debut. Perumal cast Ganesan after being impressed with his performance as Nur Jahan in the Sakthi
