• Kulamagal Radhai directed by A. P. Nagarajan, who also wrote the screenplay, and produced by Spider Films.^[2][3]
• It is based on the novel Vaazhvu Engey, by Akilan.^[4][5] Cinematography was handled by W. R. Subba Rao, and the editing by K. Durairaj.^[3]
• In the final scene of this movie will take place Sivaji Ganesan was supposed to kick Sarojadevi on the shoulder in a fit of anger; however, he slipped, and his foot struck her in the stomach instead, causing her to fall heavily to the ground.
• Realizing what had happened and concerned about the impact of the kick, Sivaji Ganesan immediately asked director A. P. Nagarajan to summon a doctor. But Saroja devi laughed as she got up and told Sivaji, "I don't need a doctor, Ganesh; your foot has just done the job the doctor was supposed to do for me." When Sivaji and Nagarajan looked at her in confusion, wondering what she meant, she explained that she had been suffering from severe gas pain in her stomach for a couple of days—pain that hadn't subsided despite taking various medicines.
• She added that the kick Ganesh had delivered to her stomach had effectively cured her gas trouble. Hearing this, everyone on the set—Sivaji Ganesan, A. P. Nagarajan, and Devika—burst into laughter.
• After Sarojadevi declined the need for a doctor, the scene was filmed again, this time correctly, with Sivaji Ganesan kicking her on the shoulder and causing her to fall.
• Later, Sivaji Ganesan asked Saroja Devi about the sensation of the accidental kick. She jokingly remarked, "You know the saying about an elephant trampling Bharati's stomach? It felt exactly like that." Director A. P. Nagarajan, who was nearby, playfully elaborated on the literary analogy: "Yes, in this context, 'Bharati' represents " Abhinaya Saraswathi " (Sarojadevi), and the 'Elephant'—or " Aanaimugan "—represents Sivaji Ganesan."

The music was composed by K. V. Mahadevan.^[6][7]
