Sumathi En Sundari

Sumathi En Sundari is a 1971 Indian Tamil-language romantic comedy film, directed by C. V. Rajendran. The film stars Sivaji Ganesan and Jayalalithaa. It is a remake of the 1967 Bengali film Nayika Sangbad. The film was released on 14 April 1971.

Production
The filming was completely held at Kodaikanal and was also held at Thekkady, Kerala for 20 days. Rajendran wanted two horses for an important scene however after he found one of the two horses to be skinny and rides only in reverse he decided not to change the horse as it would become difficult to obtain the call sheets of Ganesan so he shot the scene with Nagesh riding in skinny horse and Ganesan riding a much healthier horse converting into a humorous scene.

Soundtrack
The music was composed by M. S. Viswanathan. "Pottu Vaitha Mugamo" is the first song that S. P. Balasubrahmanyam sang for a Ganesan film; another man was originally to sing the song, but Viswanathan chose Balasubrahmanyam. That song is based on Valaji raga.
