Ganesan was one of the "three biggest names of Tamil cinema", the other two being M. G. Ramachandran and Sivaji Ganesan. While Sivaji Ganesan excelled in dramatic films and M. G. Ramachandran was popular as an action hero, Gemini Ganesan was known for his romantic films. A recipient of the Padma Shri in 1971, he had also won several other awards including the Kalaimamani, the MGR Gold Medal, and the Screen Lifetime Achievement Award.
