The film marks a major cinematic reunion for Kamal Haasan and Rajinikanth, who last appeared together in a full-length role in Ninaithale Inikkum (1979). They later shared screen space briefly in Thillu Mullu (1981), where Kamal Haasan made a cameo appearance. Their journey together began much earlier with Apoorva Raagangal (1975), directed by K. Balachander, which also featured Srividya, Sundarrajan, Nagesh, and Jayasudha.
