Govindan, who previously worked as publicity designer, expressed interest in producing a film with S. P. Muthuraman as director which eventually became Anbu Thangai.^[5] The film began production in early February 1973 and it was launched at AVM Studios on 3 February 1973.^[6] Guhanathan, who co-produced the film, wanted Muthuraman to direct the film; however Muthuraman felt if Jayalalithaa was not comfortable working with him she can choose another director. When Jayalalithaa learned that the film is being directed by Muthuraman who previously worked in Enga Mama as assistant director she agreed to the choice.^[4][7] Kamal Haasan, who was a dance assistant to K. Thangappan, made a cameo appearance as the Buddha in a song.^[4]

The music was composed by K. V. Mahadevan,^[8] marking his first collaboration with S. P. Muthuraman.^[9]

Anbu Thangai was released on 30 August 1974.^[10] A critic from Kalki praised the performances of the cast, Guhanathan's story and Muthuraman's direction and included it among the list of films on the bond between a brother and sister after Pasamalar.^[3] According to S. P. Muthuraman, despite the film's average response at the box office, the producer Govindan turned a profit.^[11]
