"Apoorva Raagangal" was released on 15 August 1975. Despite exploring the concept of relationships between people with wide age gaps, which challenged Indian social mores, it received critical acclaim and became a commercial success, and a breakthrough for Srividya and Haasan. The film won three National Film Awards, including Best Feature Film in Tamil, and three Filmfare Awards South in the Tamil branch: Best Feature Film, Best Director for Balachander and Best Actor for Haasan, and a Special Award for Srividya. It was remade in Telugu as "Thoorpu Padamara" (1976) where Srividya reprised her role, and in Hindi by Balachander as "Ek Nai Paheli" (1984) where Haasan reprised his role.
