S. S. Rajendran (known popularly as SSR) was initially a theater artist like Shivaji who starred in many plays for Dravidar Kazhagam. Like Sivaji, he debuted in Parasakthi. Being one of the most popular stars of Tamil cinema in the 1950s and 60s, he raised funds for DMK and acted in movies glorifying Dravidian ideologies. Personal problems led to a fall in his film career and in politics. Having spent most of his earnings for the party he found himself in a deep financial crisis. His movie career brought another star of DMK, M. G. Ramachandran, to cross swords with him, and his political ambitions brought Karunanidhi against him.

Sensing trouble in all quarters SSR made a highly political movie, Thangarathinam, to coincide with the 1967 election campaign to prove his loyalty to the party. The party won a landslide victory in the 1967 general elections, but soon after the elections the animosity between SSR and Karunanidhi deepened. SSR complained of threats to his life and eventually left DMK to join Congress along with his old friend Sivaji. His aspirations as a political stalwart and as a film superstar were overshadowed by M. G. Ramachandran.
