A remake of the Hindi film Chand Aur Suraj (1965), it stars Gemini Ganesan, Savitri, Balaji and Vijaya.

In the film, after a man's faked death, the lives of his family members change drastically when they receive money from an insurance company he cheated.

Ramanathan wants to help his younger brother Ravi to pursue MBBS, and to fund his education, he takes an insurance policy for ₹100,000 (equivalent to ₹6.0 million or US$70,000 in 2023).

Annavin Aasai was a remake of the Dulal Guha-directed Hindi film Chand Aur Suraj (1965),[2] and was the first production of K. Balaji's company Sujatha Cine Arts.

[11] The following week, on 12 March, The Indian Express said, "Dynamic performance by all the artistes – [Savitri] particularly – and a couple of good tunes by K. V. Mahadevan attempt to revive our sagging hopes.

"[12] T. M. Ramachandran of Sport and Pastime said the "treatment by director Dada Mirasi is so pedestrian that the film fails to sustain interest completely."

[13] According to historian Randor Guy, it was not a major success but "good enough to boost the morale of [Balaji] to stick to the new role" of a producer.
