Kozhi Koovuthu is the directorial debut of Gangai Amaran. The title was suggested by his brother Ilaiyaraaja, who suggested Amaran to take up direction as a career.[5] It is also the acting debut of Viji.[6] Editing was jointly handled by B. Lenin and V. T. Vijayan, although the song "Edho Moham Edho Dhagam" was edited exclusively by Vijayan using already shot montages as Lenin was unavailable.[7]
