However, the legacy of Sivakumar films is not confined to the past; it acts as a foundation for the future of Tamil cinema. After retiring from acting to focus on painting and public service, Sivakumar’s cinematic DNA found a new vessel in his sons, actors Suriya and Karthi. The "Sivakumar brand" of cinema—characterized by strong family values, emotional sincerity, and a connection to the soil—has been successfully carried forward by his sons through their production house, 2D Entertainment. When one watches Suriya in films like Vaaranam Aayiram or Karthi in Kadaisi Vivasayi , one sees the echoes of their father’s emotive capacity and commitment to meaningful content.
In the 1970s, Sivakumar explored more complex narratives. He collaborated with directors such as K. Balachander and Bharathiraja. In Balachander's " Sindhu Bhairavi " (1985), he played a carnatic singer. The role earned him a Filmfare Award and solidified his status as a performer. Other notable films from this time include " Rosaappo Ravikkai Kaari " and " Annakkili ," which introduced realistic storytelling in Tamil cinema. sivakumar films
