Thillana Mohanambal is a 1968 Indian Tamil-language romantic musical dance film written, directed and produced by A. P. Nagarajan. The film stars Sivaji Ganesan, Padmini and T. S. Balaiah, with A. V. M. Rajan, Nagesh and Manorama in supporting roles. It tells the story of Shanmugasundaram, a nadaswaram player who falls in love with Mohanambal, a Bharatanatyam dancer who reciprocates his feelings, but unfortunate circumstances and their egoistic nature prevents them from confessing their love for one another. How they overcome their self-created obstacles and those created by the people around them forms the rest of the story.
