During the discussion at Mahabalipuram, Selvaraj narrated the story of Maruthavachi to Panchu Arunachalam who liked the plot and decided to produce the film. Selvaraj and Arunachalam wanted S. P. Muthuraman to direct the film as he was busy with other commitments, Selvaraj chosen duo Devaraj Mohan to direct the film. The film was entirely shot at Thengumarada near Sathyamangalam and was produced under the budget of 400000 with Devaraj Mohan being paid 7500 together and Ilayaraja and Selvaraj both receiving 2500 as remuneration. According to producer G. Dhananjayan in his book Pride of Tamil Cinema, the scene of Annam offering her lover to Sumathi was inspired from 1962 film Senthamarai and the climax scene of the theatre getting burnt was similar to the climax of Kannagi (1942).

The film's soundtrack was composed by Ilaiyaraaja who made his debut as composer with this film and lyrics were written by Panchu Arunachalam. Selvaraj insisted to have Pavalar Brothers to compose the music but Panchu selected Rasaiyya to compose as he felt it was not appropriate to have three brothers to compose music. Panchu Arunachalam added "Ilaiya" (Ilaiya means younger in Tamil language) as prefix in his name Raaja and he named as "Ilaiyaraaja" because in the 1970s there was one more music director A. M. Rajah who was a popular one. For the soundtrack, Ilaiyaraaja applied the techniques of modern popular film music orchestration to Tamil folk poetry and folk song melodies, which created a fusion of Western and Tamil idioms. The song "Machanai Paartheengala" was originally composed and sung at a marriage by Ilaiyaraaja and his orchestra even before the film's release. Raja wanted Lata Mangeshkar to sing the title song however due to her non-availability he chose Janaki to sing the song. Although before choosing Janaki, the famous folk artist at that time L. R.Eswari was preferred. Eswari apparently rejected as the music direction is by a newcomer. Ilaiyaraaja after that never used L.R.Eswari for ever. The violin portions of the song were used by music director K for the song "Bar Anthem" in Mugamoodi (2012). The song "Sonthamillai Banthamillai" is based on Nadanamakriya raga. All the songs were well received with Dhananjayan noting that the songs "helped tremendously in film's success".
